DevilutionX-focused Diablo I & Hellfire knowledge
UV's Compendium
This site is a growing collection of tools, references, and strategy guides for players who want clearer access to the underlying mechanics of Diablo I & Hellfire in modern DevilutionX play.
Calculators
Tools for the numbers
Use calculators for shopping, item pricing, affix ranges, qlvls, and other mechanics where Hellfire's hidden math is easier to work with when the formulas are handled for you.
Guides
Practical play references
Read and watch focused guides for classes, shopping, quests, bosses, Hellfire additions, and DevilutionX-specific behavior, with an emphasis on useful details and practical implementation.
Project mission
Preserve the knowledge. Improve the tooling.
Diablo I has decades of community knowledge behind it, but much of that information is spread across older guides, forum posts, and calculators built for a different era of the web. Other information has been completely lost to time as sites have gone down as people left the community. This site is intended to gather and preserve that knowledge into a clean, maintainable home that can grow naturally as new tools and guides are added.
The primary focus is DevilutionX play which is the definitive way to play Diablo 1 and Hellfire in the modern era. I host references that make Diablo and Hellfire mechanics easier to understand, calculators that handle the tedious math, and guides that explain how to optimize your play and min-max your characters.
