Awkward Kamikaze

A kamikaze spell that you know is powerful, but you don't know how well it works, since you can't exactly practice blowing yourself up.

Upon use, you will drop to zero HP and you become unconscious. All enemies within 35ft of you will take 8d20 damage regardless of AC.

Additionally, roll 1d4 to determine this spell's damage type: 1 for fire damage, 2 for pierce damage, 3 for necrotic damage, and 4 for force damage

If allies are caught in this blast, roll 1d4. Even numbers allow allies to heal 1d4 HP, odds damage allies for 1d6 force damage.
