How Diablo 4's Damage System Works

Diablo IV uses a multiplicative damage bucket system, which is fundamentally different from most ARPGs. Instead of all damage bonuses adding together into a single pool, your stats are divided into distinct categories that multiply against each other. This means the diversity of your stat investment matters far more than stacking a single type of bonus.

The six primary damage buckets in Diablo IV are:

  1. Base Damage — Weapon damage multiplied by the skill's damage percentage
  2. Main Stat — Strength, Dexterity, Intelligence, or Willpower providing a passive multiplier
  3. Additive Damage Pool — All [+%] bonuses combined
  4. Vulnerable Damage — Separate multiplier against Vulnerable-debuffed targets
  5. Critical Strike — The critical hit multiplier scaled by your Crit Chance
  6. Global [x] Multipliers — Independent multipliers from Legendary Aspects and Key Passives
