Cloak of Ursula

An energizing magical force surrounds you, manifesting as a spectral storm that covers you and your gear. For the duration, you have a +5 bonus to initiative. If a creature hits you with a melee attack, the creature takes 5 lightning damage.

When you have dealt a total of 15 lightning damage, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, both the lightning damage dealt on hit and the total damage threshold increase by 5 for each slot.
