Bard, Sorcerer, Warlock, Wizard - Cantrip Level Spell
Casting Time: 1 Action
Components: Verbal and Somatic
Duration: 1 Round
Reference: PHB 218
You extend your hand and trace a sigil of warding in the air. Until the end of your next turn, you have resistance against bludgeoning, piercing, and slashing damage dealt by weapon attacks.
My Comments: Sure, it’s a cantrip so you can’t expect much, but still, I can’t say I’m impressed. Basically, you give up an action in one turn to reduce the damage you’re going to take for ONE round.
Personally, I think you’re probably better off using your action to do some damage.
