Blaze of Glory

You choose to go down in a blaze of glory. Until the end of your next turn, you do not fall unconscious from being at 0 hit points, you are immune to the charmed, frightened, grappled, paralyzed, restrained, and stunned conditions, and you have advantage on all attack rolls. When you take damage during this round, you instead gain 1 failed death saving throw for every 20 points of damage taken. Once you’ve used this spell, you cannot cast it again until you complete a short or long rest.
