Feat: Deadly Simplicity

When you are wielding your deity's favored weapon, increase the damage die size of that weapon by one step.

If your deity's favored weapon is an unarmed attack (such as a fist, if you worship @UUID[Compendium.pf2e.deities.Item.Irori]) and its damage die is smaller than d6, instead increase its damage die size to d6.
