Diablo 1 / Hellfire / DevilutionX

Building a powerful character in Diablo 1 is about much more than gaining levels. Character development also means finding strong equipment, improving that equipment where possible, developing useful spells, raising attributes, and taking advantage of permanent upgrades such as shrines.

The fastest approach is to work toward several of those goals at the same time rather than treating leveling, item hunting, shopping, and character development as unrelated grinds.

The general strategy is:

  1. Push into deeper dungeon areas as soon as you can clear them efficiently.
  2. Move into higher difficulties when the additional experience becomes worthwhile.
  3. Farm Hell for equipment while it still provides useful experience.
  4. Use Church and Catacombs runs for shrine hunting and spell development.
  5. Improve worthwhile equipment as you acquire it, particularly in Hellfire.
  6. Continue moving toward whatever areas give your particular character the best experience and useful rewards per minute.

The level ranges below are guidelines rather than strict requirements. Class, equipment, spell levels, player skill, and whether you're playing Diablo, Hellfire, or DevilutionX can all change the ideal transition points.

Quick Leveling Route

Recommended leveling activities by character level
Character Level Recommended Activity
1–7 Normal Church
8–12 Normal Catacombs
12–20 Normal Caves
21–22 Nightmare Church, especially for shrines
22–26 Nightmare Catacombs, especially for shrines
27–32 Normal Hell for leveling and item finding
33–34 Hell Church, especially for shrines
34–40 Hell Catacombs for leveling and shrine hunting
40–44 Hell Catacombs or Nightmare Hell
44–47 Nightmare Lazarus and dungeon level 16
48–50 Hell Caves

These transitions are deliberately flexible.

A new character may have difficulty entering Normal Caves at level 12 and may need to remain in the Catacombs until closer to level 16 or 17. Likewise, higher-level characters should prioritize clear speed rather than following the table blindly.

If Nightmare Hell gives you better experience per minute than Hell Catacombs, run Nightmare Hell. If Hell Catacombs still gives good experience while also providing useful shrines, stay there.

Efficiency matters more than matching an exact level range.

Develop Everything Together

A well-developed character needs several things:

  • Character levels
  • Strong equipment
  • High attributes
  • Useful spells at high levels
  • Permanent equipment improvements where available

Whenever possible, choose activities that improve more than one of these at once.

Normal Hell is especially useful during the middle levels because it combines experience with access to excellent equipment drops. Later, Nightmare and Hell Church or Catacombs runs can provide experience while also giving repeated access to useful shrines.

Character development, fast or slow, works best as an overlapping process rather than a series of completely separate grinds.

Fast Clearing With Teleport and Chain Lightning

Once your character has sufficient equipment, mana, and spell levels, Teleport combined with Chain Lightning can clear Church and Catacombs extremely quickly.

Teleport aggressively between populated areas and use Chain Lightning to eliminate large groups. High Armor Class and fast hit recovery become especially useful when teleporting directly into groups of enemies.

In original Diablo, very high Chain Lightning spell levels can run into problems because of the game's limited missile sprite system. Experienced vanilla players may therefore deliberately limit Chain Lightning rather than raising it indefinitely.

DevilutionX fixes this limitation. When playing DevilutionX, higher Chain Lightning spell levels are beneficial and there is no need to restrict the spell because of the original bug.

Gear Progression

Equipment is an essential part of character development. Leveling quickly does little good if your gear falls far enough behind that your clear speed collapses.

There are two primary ways to obtain better equipment:

  • Find it in the dungeon.
  • Buy it from Griswold, Wirt, or Adria.

Hellfire adds another major element:

  • Improve equipment you already own using Oils.

A complete examination of item generation, dungeon farming, affix levels, and shop mechanics deserves a separate Item Finding and Shopping Guide. The goal here is instead to cover the major equipment targets and strategies that matter while developing a character.

Farming Hell for Equipment

The Hell dungeon, levels 13–16, remains one of the best places in the game to hunt equipment.

Normal Hell is particularly useful while developing a character because monsters die much faster than their Nightmare or Hell counterparts while still providing access to excellent magical items.

Lazarus Runs

Archbishop Lazarus remains one of the most useful farming targets in both vanilla multiplayer and DevilutionX.

A Lazarus run provides several high-level unique monsters in rapid succession. After killing Lazarus and his companions, you can continue directly into dungeon level 16 and clear additional high-level monsters.

This makes Lazarus runs useful for both equipment farming and character development.

Warlord of Blood Runs

The Warlord of Blood quest on dungeon level 13 adds another excellent farming opportunity.

The Warlord provides a guaranteed drop, while his room contains:

  • 2 Armor Racks
  • 6 Weapon Racks

The encounter and racks can be cleared very quickly, making the room useful both for equipment and for generating gold by selling unwanted items.

This strategy is primarily useful in DevilutionX multiplayer or vanilla single player.

Vanilla multiplayer does not include the Warlord quest. Vanilla single player can include it, but quest randomization means you cannot count on it appearing in every game.

DevilutionX can enable the single-player quests in multiplayer and disable quest randomization, allowing quest-dependent farming routes to be repeated consistently.

Useful Quest Equipment While Developing

Several quest rewards are worth collecting on a fresh character even though most are stepping stones rather than final endgame equipment.

Examples include:

  • Ring of Truth, from the Poisoned Water quest on dungeon level 2
  • Undead Crown, from King Leoric on dungeon level 3
  • Arkaine's Valor, from the Valor quest on dungeon level 5
  • Veil of Steel, from Lachdanan on dungeon level 14

Ring of Truth and Arkaine's Valor are particularly useful during an initial playthrough when you do not already have strong equipment available to hand down from another character. They will generally be replaced later, but they can smooth out the early progression considerably.

The Veil of Steel has considerably more staying power. Its +50% Resist All alone provides two-thirds of the normal 75% resistance cap, along with +15 Strength, +15 Vitality, and +60% Armor. The main tradeoff is -30 Mana. Jarulf's Guide assigns the Veil a value of 63,800 gold, making it an exceptionally high-value helm.

That high value has another useful application in Hellfire targeted shopping. Using the Veil as your high-value helm can eliminate many cheaper helm results from shop generation, helping narrow the pool when you are deliberately shopping for expensive magical helms.


Adria

Adria is primarily useful for:

  • Spellbooks
  • Magical staves
  • Mana supplies
  • Elixirs once they become available

Her inventory refreshes every time you return from the dungeon, so it is worth checking her whenever you come back to town while developing a character. Even if you do not need anything immediately, repeated checks provide additional opportunities for useful spellbooks and elixirs.

In multiplayer, Adria begins selling elixirs at character level 26. In single player, Adria and Pepin begin selling them after you have reached dungeon level 13, the Hive, or the Crypt. Elixirs of Vitality cannot be purchased and must be found.

Adria does not generally build your high-Magic "reading glasses" equipment set directly, since the only equippable items she sells are staves. Her value for spell development comes mainly from repeatedly providing the books that the reading set allows you to use.


General Armor Targets

Awesome Full Plate Mail of Harmony

For most characters capable of wearing it, one of the strongest general-purpose armor targets is the Awesome Full Plate Mail of Harmony.

A plain Awesome Full Plate Mail can be excellent while developing a character, but Harmony becomes increasingly important at higher difficulty.

Other useful suffixes include:

  • of Stars, for additional attributes
  • of Sorcery, for additional Magic
  • of the Lion, for additional Life
  • of Deflection, for reduced damage from enemies

Harmony is generally preferred because high-level characters benefit enormously from reaching the fastest hit-recovery speed. Jarulf lists Harmony as the highest hit-recovery tier.

Putting Harmony on the armor also leaves jewelry suffixes available for effects that may be more valuable there.

High base Armor Class matters as well. An ideal Awesome Full Plate Mail of Harmony should therefore combine a strong Awesome roll with high base armor.

For this reason, an Obsidian Full Plate Mail is generally less attractive than armor with a strong AC prefix such as Saintly, Awesome, Holy, or Godly. Resistances are extremely important, but they can usually be obtained more efficiently from jewelry, shields, or helms rather than sacrificing the large Armor Class contribution available from the armor prefix.

Naj's Light Plate

Naj's Light Plate can be useful for low-Strength spellcasters or characters being equipped before they can comfortably wear Full Plate Mail.

It generally loses out to stronger endgame armor eventually, but its low requirements can make it an excellent transitional piece.

Armor of Gloom

In DevilutionX Hellfire versions where its original drop-generation problems have been corrected, Armor of Gloom is another important option, particularly for the Monk.

Its unusual defensive properties can make it extremely powerful, but using it also means obtaining Harmony somewhere other than the armor slot.


Jewelry

Jewelry is one of the most flexible parts of Diablo gearing because rings and amulets can provide resistances, attributes, Mana, chance to hit, Life, or hit recovery without occupying your major weapon and armor slots.

It is usually more useful to evaluate jewelry as a prefix + suffix combination than to judge either affix in isolation.

High-End Jewelry Prefixes

  • Obsidian: +31–40% Resist All
  • Dragon's: +51–60 Mana
  • Drake's: +41–50 Mana
  • Gold: +21–30% To Hit

Obsidian is the highest Resist All prefix that can occur on jewelry; Emerald provides +41–50% Resist All but cannot spawn on jewelry.

High-End Jewelry Suffixes

  • of the Zodiac: +16–20 All Attributes
  • of Wizardry: +21–30 Magic
  • of the Heavens: +12–15 All Attributes
  • of Perfection: +21–30 Dexterity

Jarulf's affix tables confirm those ranges.

Particularly desirable combinations include:

  • Obsidian Jewelry of the Zodiac
  • Dragon's Jewelry of the Zodiac
  • Dragon's Jewelry of Wizardry
  • Gold Jewelry of the Heavens
  • Gold Jewelry of Perfection

Dragon's of the Zodiac is especially versatile because it combines a large Mana increase with a substantial boost to every attribute.

Gold cannot combine with Zodiac because of the affix-level relationship between the two, making Heavens and Perfection particularly attractive suffixes on Gold jewelry.

Mid-Tier Mana and Resistance Prefixes

Perfect jewelry is not necessary to build a strong character. Many lower-tier affixes remain extremely useful.

For Mana:

  • Snake's: +21–30 Mana
  • Serpent's: +30–40 Mana
  • Drake's: +41–50 Mana

For Resist All:

  • Amber: +16–20% Resist All
  • Jade: +21–30% Resist All

Jarulf lists these exact ranges in the affix tables.

Strong single-resistance prefixes are also valuable:

High-value single-resistance jewelry prefixes
Resistance 41–50% 51–60%
Magic Crystal Diamond
Fire Garnet Ruby
Lightning Cobalt Sapphire

Fire and Magic resistance tend to be particularly useful, but the ideal resistance setup depends on the monsters actually present on the dungeon level.

Mid-Tier Jewelry Suffixes

Useful attribute suffixes include:

  • of the Moon: +4–7 All Attributes
  • of the Stars: +8–11 All Attributes
  • of Sorcery: +16–20 Magic

Useful Life suffixes include:

  • of the Fox: +10–15 Life
  • of the Jaguar: +16–20 Life
  • of the Eagle: +21–30 Life
  • of the Wolf: +30–40 Life
  • of the Tiger: +41–50 Life
  • of the Lion: +51–60 Life

of Harmony can also be extremely useful when your armor or helmet does not already provide fastest hit recovery.

Swap Jewelry for the Dungeon You're Running

You do not necessarily need all three resistances maxed on every dungeon level.

If the monsters currently present do not deal a particular damage type, resistance to that element is doing nothing for you.

A useful strategy is therefore to keep several specialized resistance jewels available and rotate them as necessary. For example:

  • Garnet/Ruby Jewelry of the Heavens for Fire
  • Cobalt/Sapphire Jewelry of the Heavens for Lightning
  • Crystal/Diamond Jewelry of the Heavens for Magic

This lets you concentrate your equipment bonuses on the resistances actually relevant to the enemies you're fighting rather than forcing the same resistance configuration everywhere.

Ring of Engagement — Hellfire

The Ring of Engagement is a useful niche option for melee characters because of its Puncturing effect.

In Hellfire, Puncturing reduces the target monster's Armor Class by 50%, substantially improving effective hit chance against heavily armored enemies. Barbarians receive an additional 12.5 percentage-point benefit from this mechanic.

This can be especially helpful for low-Dexterity physical characters such as Warriors and Barbarians.

Jewelry of the Dark

Jewelry of the Dark is a niche but extremely useful option for low-light "ninja" builds.

Each item of the Dark provides -40% Light Radius, and -80% is the exact lower limit at which additional reduced light radius stops having an effect. Light radius also affects the distance at which monsters become activated.

At -80% Light Radius, most monsters must be extremely close before they notice you. Combined with Infravision, this allows a character to move quietly through a level and engage enemies individually instead of waking entire groups.

Steel Jewelry of the Dark is particularly coveted because the additional To Hit complements the build well. Other useful prefixes that can occur alongside the relatively low-level Dark suffix include:

  • Pearl
  • Crimson
  • Azure
  • Topaz
  • Amber
  • Raven's
  • Snake's

Good prefixed versions can be difficult to find, so plain Jewelry of the Dark is still worth keeping.

This is also one of the few equipment finds particularly worth watching for while running the Catacombs. If you're already clearing Catacombs repeatedly for Enchanted and Hidden Shrines, you may as well keep an eye out for useful Dark jewelry at the same time.

The full equipment and playstyle requirements of a ninja build deserve a separate guide.


Weapon Targets

Spellcasting: Dreamflange

For characters relying heavily on spells, Dreamflange is one of the strongest weapons in the game.

It provides:

  • +30 Magic
  • +50 Mana
  • +50% Resist Magic
  • +1 Spell Level
  • +20% Light Radius

That combination of Magic, Mana, resistance, and spell level makes it extremely difficult for ordinary magical spellcasting weapons to compete with.

Monk

The Monk has one of the clearest weapon choices in Hellfire:

King's War Staff of Haste/Speed

Staves are the Monk's natural melee weapon. He attacks considerably faster with a staff than other classes, can block while wielding one, and gains his adjacent quarter-damage ability while using a staff, allowing a swing at the primary target to also damage enemies beside it.

With Speed or Haste, Jarulf lists the Monk's staff swing at 0.30 seconds, faster than his other conventional weapon categories.

Because staves do not provide the same Blood/Vampires life- and mana-stealing suffix options available on conventional melee weapons, the King's + Haste/Speed combination is a particularly straightforward offensive target.

For the rest of his equipment, the Monk benefits heavily from avoiding damage rather than trying to absorb it. High Armor Class, high Dexterity for blocking, strong resistances, and Mana Shield all help compensate for his relative fragility.

Armor of Gloom is an excellent armor target where available, while Awesome Full Plate Mail of Harmony remains a strong alternative. Royal Circlet is generally an excellent helmet because its defensive and Mana-related bonuses work well with Mana Shield, although Undead Crown remains useful when life stealing is specifically desired.

Bard

The Bard's dual-wielding ability makes her equipment unusually flexible.

For physical combat, she generally wants at least one sword because her character-damage formula receives a major benefit when at least one equipped weapon is a sword. Properties such as King's damage bonuses from both weapons are combined before being applied to the weapons' combined damage.

A common primary weapon is:

King's Sword of Haste/Speed/Vampires

The second weapon can then fill whatever the rest of the equipment set lacks, with possibilities such as King's, Obsidian, Emerald, or Strange weapons carrying Haste, Speed, Vampires, or attribute bonuses.

Spellcasting Bard

The Bard also has a spellcasting equipment combination unavailable to any other class:

dual Dreamflanges.

Equipping two Dreamflanges allows her to stack the exceptional spellcasting properties of both weapons, making it an extremely powerful pure-caster setup.

However, maximum spellcasting bonuses are not always the best defensive choice. On dangerous high-difficulty levels, Dreamflange + Stormshield can be preferable because the shield provides blocking and substantial defensive value while Dreamflange retains its major caster bonuses.

The Bard can therefore move between a highly aggressive dual-Dreamflange caster configuration and a more defensive Dreamflange-and-shield configuration depending on the area and monster composition.


Developing Spells

Spell development matters even for characters that are not primarily spellcasters.

One useful strategy is to maintain a separate set of "reading glasses": equipment chosen primarily for its Magic bonuses.

Equip the high-Magic gear, read the spellbook, and then switch back to your normal combat equipment.

GainTrain's original practical spell milestones included:

Practical spell-development milestones
Spell Development Target
Fireball 9+
Chain Lightning 8+
Stone Curse 2+
Teleport 4+
Flash 11+
Other useful spells At least 1

These should be treated as useful milestones, not stopping points.

If you have sufficient Magic and another useful spellbook, there is generally little reason not to read it.

Higher Fireball levels remain useful. Additional Stone Curse levels increase its duration. Teleport becomes progressively cheaper until its mana cost reaches its minimum of 15 Mana. Jarulf lists its initial cost as 35 Mana with a reduction of 3 per spell level until the spell reaches its minimum.

Chain Lightning is unusual only in original Diablo because of the vanilla missile limitation.

When playing DevilutionX, higher Chain Lightning levels are beneficial, so there is no reason to deliberately restrict the spell because of that original limitation.


Putting It All Together

Character development, fast or slow, is not simply:

Level 1 → Level 50

It is an overlapping cycle:

Level → find gear → shop for upgrades → improve equipment → develop spells → use shrines → raise difficulty → repeat

Early on, concentrate on gaining levels and acquiring whatever equipment allows you to push deeper.

During the middle levels, begin combining experience with Normal Hell equipment farming and Nightmare shrine hunting.

As your character becomes stronger, Hell Church and Hell Catacombs can develop several parts of the character simultaneously. They can provide useful experience, Enchanted and attribute shrines for character development, and Hidden Shrines for permanently improving the durability of important equipment. Catacombs runs also give you an opportunity to watch for specialized low-level affixes such as Jewelry of the Dark while you're already shrine hunting.

In Hellfire, use Oils to continue developing worthwhile equipment instead of automatically replacing an excellent item simply because its starting durability, accuracy, or weapon damage was imperfect.

At higher levels, prioritize whatever dungeon and difficulty gives the best combination of experience, useful drops, shrines, and permanent equipment development for what your character still needs.

A fully developed character is the result of leveling, equipment, attributes, spells, shrines, and permanent item improvements all progressing together.
