Cantrips (at will): fire bolt, minor illusion, prestidigitation, shocking grasp

Reactions

Illusory Self (Recharges on a Short or Long Rest). When a creature Rath can see makes an attack roll against him, he can interpose an illusory duplicate between the attacker and him. The attack automatically misses Rath, then the illusion dissipates.
