Illusion damage question
Clones do no damage unless they apply conditions with their attacks, in which case it is based off of your personal condition damage and duration.
Phantasms do damage based off of the exact stats as normal damage from you. Phantasms inherit all basic stats from you with the exception of vitality. This means they inherit your power (so might on you affects them, but might on them does not), your precision (but not your critical chance, so fury on you does not affect them), and your ferocity.
And also worth mentioning, they only inherit the power, not the damage modifiers from runes or traits. For example, the potentially 9% increased damage from “compounding power” only increases your own damage, not the phantasm damage.
