You’ve learned to finely control your Power. Your Power ability score increases by 1, to a maximum of 20.

You can give a number of creatures equal to 1 + your Power level immunity against your Powers and features; they take no damage and trigger no effects, nor can they be valid targets for your Powers. For instance, you can’t choose to sculpt your Power around a creature and then stick a grenade Power to them. You may change which creatures receive this benefit on your turn.
