Dealing Physical Damage

A weapon hit is one number built in a fixed order, and the order is why "+% Enhanced Damage" on the weapon is worth several times the same number on a ring. The DPS Simulator runs exactly this chain; this page is the chain written out, with Crushing Blow and Open Wounds, which are not part of it, beside it.

The order

The Amazon Basin's attacker list, as the game applies it:

1. The weapon's base damage roll.
2. The ethereal bonus: +50% on an ethereal weapon.
3. Enhanced Damage on the weapon (its own properties, its socketed runes and jewels, the runeword's): a percentage of the base, floored.
4. + Minimum and Maximum Damage on the weapon and "Adds X–Y damage" anywhere: flat, added next.
5. + Damage (the flat "+X to Damage" affixes).
6. % Damage from everything that is not the weapon — your Strength and Dexterity bonus (weapons.txt StrBonus / DexBonus: a sword takes 100% of Strength, a bow 100% of Dexterity, a Matriarchal Javelin 80 / 50), off-weapon Enhanced Damage from gear, charms and skills, and Damage to Demons / Undead when the target is one — all added together into one multiplier.
7. Deadly Strike, Critical Strike or a mastery's critical: one roll, double the physical damage; they never stack.
8. The unit's own critical chance.
9. Elemental damage from the weapon and gear, which is its own number (Dealing Elemental Damage).
10. % Skill Damage: the skill's multiplier (Zeal, Smite, Fury …).
11. Conversion of physical damage to another element (Berserk, Fire Arrow …).
12. The source penalty (a mercenary's, a pet's, the player-versus-player cut).

hit = ⌊base × (1 + weapon ED) + flat⌋ × (1 + stat bonus + off-weapon ED + vs-type) × (2 if critical) × skill %

Critical hits

Deadly Strike, Critical Strike and the weapon masteries' critical all double the physical part; the game checks them one after the other and the first success ends it, so the chance of a double hit with two sources is 1 − (1 − DS)(1 − CS). The Basin lists what Deadly Strike does not double: elemental damage, Crushing Blow, and the damage of Impale, Dragon Talon, Dragon Tail, Dragon Flight, Sacrifice and Smite. See Deadly Strike.

Beside the chain: Crushing Blow and Open Wounds

Crushing Blow is not a damage bonus: it removes a fraction of the target's current life before the hit's own damage is applied — 1/4 from a melee hit, 1/8 from a ranged one, half that against bosses and champions, 1/10 and 1/20 against players and mercenaries — divided by the players setting in the game and reduced by the target's physical resistance. Open Wounds is a bleed: for 8 seconds after the hit the target loses life every frame on your level's bracket (the Basin's table), no resistance applies, monster regeneration stops, and a second hit only restarts the clock. Both need the attack to hit (Chance to Hit), both ignore Deadly Strike, and neither is absorbed by Energy Shield.

After the hit

The target's physical resistance (Physical Damage Reduction on a player, the monster's ResDm) takes its percentage, Amplify Damage and Decrepify lower it, and a physical immune takes nothing until the immunity is broken. Against a player the whole chain's result is multiplied by 17% first (Player versus Player).
