You cast a large, white flame with destructive capabilities. If the spell hits the target's current health cuts in half. If the number is .5 round it up. If the save fails the spell goes through as normal. If the save succeeds the target takes 1d8 of damage. No matter if the spell succeeds or not the user's health drops to half of the current health. The spell can't be cast by a Dragon or a Dragonborn. If the target is a Dragon or a Dragonborn the target's health drops to 0, but the user's health drops to 1. The spell needs a long rest to recharge.
