Choose as many creatures as you want within range to set their hit points to maximum, for all the hit points of all the creatures were missing in total you make a constitution saving throw and, on a fail, take all this damage rounded up onto yourself, on a success you take half rounded down. If your hit points would be set to 0 with any damage left, your hit points are in the negatives instead, say if you have 5 hit points and take 6 from this spell you are now at -1, you don't need to make a death save for 24 hours but If you aren't healed back to at least 1 hit point by the time 24 hours have passed you die, and when you die from this spell your body turns to dust dropping all your items on the ground below you. This spell can be cast with a reaction to someone within range dropping to 0 hit points, requires only the verbal component with no spell slot needed and no limit to range if you would die from this spell, if this happens it has no limit to the number of creatures this spell can heal. This spell only works on creatures that aren't constructs and if its undead it has to still have blood or flesh.
