Angel Arm

Trigger: This Limit Break becomes available once per long rest. Can only be triggered when the player has less than 10% of their health.

Effect: For the duration of this turn, the Aasimar Fighter gains the following benefits:

• Divine Channeling: Your body becomes a conduit for celestial energy. You gain a flying speed equal to your walking speed, and you hover. You are immune to the blinded and deafened conditions.
• Angel Arm Blast: You can make one single, powerful ranged spell attack (using Dexterity as your spellcasting ability) against a creature you can see within 120 feet. On a hit, the target takes 10d10 radiant damage. This attack ignores resistance to radiant damage and treats immunity as resistance.
• Celestial Implosion: If the target of your Angel Arm Blast is reduced to 0 hit points by this attack, it explodes in a burst of divine energy. Each creature within 15 feet of the target must make a Dexterity saving throw (DC = 8 + your Proficiency Bonus + your Dexterity modifier), taking 4d6 radiant damage on a failed save, or half as much on a successful one.
