So when changing into a separate identity other than the player, the power glove from artifacts does not stack onto the damage you deal as say an allay or vex.

"Artifacts uses an attribute modifier to increase the player's attack damage, but it seems like Identity ignores the attack damage attribute under some conditions. The same issue can be reproduced without Artifacts by using the /attribute command, so it's is something that would have to be fixed on Identity's side."
