How it works

Attack turn

Each fight starts with your ward full and your armour unbroken. Each turn waits Attack interval, then attacks.
The turn's attack is drawn when it starts: each special attack of your equipped items at its chance, the normal attack for the chance left over. When the chances add up to 1 or more they are scaled to sum to 1, and the normal attack is never drawn. A selected spell with its own attack replaces them all.
An attack needs its ammo and, for a spell, its runes; without them the turn ends with no attack and the next turn waits again.
Every hit of the attack follows the attack sequence below; an attack with several hits waits each hit's own interval between them. Then the next turn starts.
Eating by hand or changing the spell restarts the turn: the wait starts over and a new attack is drawn. Auto eat does not.

Attack

Pre-hit effects apply first, each at its chance.
The attack misses a target with Immunity from. An avoidable attack also needs Hit chance; an unavoidable one always hits.
Damage is the sum of the hit's damage formulas. Normal damage rolls uniformly between percent × Min hit and percent × Max hit; max hit, max hitpoints, current hitpoints and damage dealt formulas deal their percent of that value; fixed and fixed range formulas deal their own numbers. Each is truncated.
A critical hit, with Critical hit chance, multiplies the damage by Critical hit multiplier, truncated. The target's Attack damage negation chance reduces it to 0.
Above 0, damage becomes trunc(max(1, d × (1 + Percent damage dealt) × (1 + the target's Percent damage taken + Percent damage taken from + Percent damage taken from attacks) × (1 − Resistance) × (1 − ward ÷ max ward) − the target's Armour)). The ward factor applies to a target with ward, and armour until it breaks.
The target loses that health and reflects Percent attack reflect of it. A target with ward also loses 1 ward, 2 with Double ward damage chance. A hit of at least the target's Armour breaks its armour when its Base armour is above 0.
On-hit effects then apply, each at its chance.

Combat level

A character's combat level is max(1, floor(Σ level × ratio)) over its combat style's combat level ratios; a level it lacks counts as 1.
An enemy's combat level is the highest over its combat styles.

Game messages

Reduces all damage taken by a flat amount equal to the Armour value. This is the final damage calculation step.: The tooltip of your Armour. It subtracts after every multiplier, and stops counting for the rest of a fight once a hit of at least its value breaks it.
Reduces all damage taken by the percent (%) difference of Current Ward / Maximum Ward. Ward is reduced by 1 per Hit (Weapon only).: The tooltip of your ward. Each hit takes 1 ward, or 2 with Double ward damage chance.
Armour Broken!: A hit of at least the target's Armour breaks it, when its Base armour is above 0. From then armour no longer reduces that target's damage taken in the fight.
This is your style Combat Level. Your Combat Level changes based on your active Combat Style.: The tooltip of your combat level, named after your current combat style. Each style weighs your skill levels by its own ratios, so changing style changes the level.
