Caustic Blood

This is a conversion of the Caustic Blood spell from Pathfinder 1e

You imbue your blood with corrosive acid. Any time you take piercing or slashing damage, a spray of acidic blood spurts from your body in a 10 ft. line towards the creature who inflicted the wound. Creatures in the area take 1d6 acid damage, which can be reduce by half with a successful Dexterity saving throw. At the start of each of the affected creature's turns, they take an additional 1d6 acid damage unless they succeed on a Dexterity saving throw, ending the effect on success.
