Total Damage
From Gloria Victis
The Total Damage statistic has three factors:
1. The weapon's base damage.
2. The character's damage multiplier which is based on equipped armor.
3. The character's strength and/or dexterity - depending on the weapon.
Some weapon damage modifiers are based on strength, like axes. Some are based on a combination of strength and dexterity, like swords. Other weapons, like bows and daggers, are based almost entirely on dexterity.
See Weapons for how weapon damage is calculated.
See Armor for more information about how armor affects weapon damage.
Here is some information about how your Attributes affect your damage output.
