Arianne's Ward

The spell creates a protective ward around a creature, absorbing some of the magical energy and storing it as a glowing mote for up to 1 minute. The ward absorbs damage equal to 2d6 + your spellcasting ability modifier. Before the spell ends, the warded creature may expend the mote to empower an attack with force damage equal to the total amount absorbed, or as additional healing when they heal a creature. The spell then ends.

The mote emits bright light in a 5ft radius. A creature may only have one mote at a time. If a creature is warded again before the mote has been expended, the spell has no effect.

An unused mote dissipates after 1 minute.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, roll an additional 2d6 for each slot level above 2nd.
