Welcome to Hell, Nephalem.
Whether you are battling Lilith in Diablo 4 or farming Baal in Diablo 2 Resurrected, the Diablo series is defined by efficiency. You are fighting a war against RNG (Random Number Generation). To win, you need to understand the hidden math behind your build.
We created these Diablo Utilities to demystify the complex mechanics of Sanctuary. Calculate your Glyph XP grinding time, solve the "Lucky Hit" equation, and plan your classic skill trees without wasting a respec token.

Lucky Hit Calculator
The most confusing stat in D4 explained. Calculate your True Proc Rate by combining Skill Base Chance, Lucky Hit Bonus, and Effect Chance.

Stop guessing how many Nightmare Dungeons you need to run. Calculate the exact number of runs to get your Paragon Glyph from Level 1 to 15 (or 21).
Calc XP →Deep Dive: How "Lucky Hit" Actually Works
In Diablo 4, seeing "+10% Lucky Hit Chance" on your gloves does not mean you have a 10% chance to trigger an effect. It is a "bucket" system that multiplies three different numbers:
- 1. Base Skill Coefficient: Every skill has a hidden base chance (e.g., Ice Shards might have 16%).
- 2. Your Bonus Stats: This is the gear affix (+Lucky Hit Chance). It acts as a multiplier, not a flat addition.
- 3. The Effect Chance: The aspect itself (e.g., "Lucky Hit: 5% chance to heal").
Our Lucky Hit Calculator does the math for you: (Base × (1 + Bonus)) × Effect. This prevents you from building around a proc that will almost never happen.

The Art of D2R Synergies
Diablo 2 is ruthless. If you misplace your skill points, you only get 3 free respecs (one per difficulty) before you have to farm "Tokens of Absolution" from Hell bosses.
The key to high damage in D2R is Synergies. Putting points into "Fire Bolt" increases the damage of "Fire Ball." Our calculator visualizes these connections, helping you decide if you should max out your main skill first or spread points into synergies for mana efficiency.
