Arcane Dodge

You hiss the ancient Draconic word for avoidance.  Until the start of your next turn, any attack roll made against you has disadvantage if you can see the attacker, and you make Dexterity saving throws with advantage.  You lose this benefit if you are incapacitated or if your speed drops to 0.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the duration extends for one additional round for every two slot levels above 2nd.
