Detonate

Touch any object, or make a weapon attack with a melee weapon, that object then becomes a bomb you can detonate at will. The bomb deals 1d12 damage to any creature within 10 ft. of it. Any creature affected by the bomb has an additional 1/6th of their maximum health dealt to them if they fail a dc 13 fortitude save. You can use a spell slot to cast this spell on a creature of cr equal to your level, if you do, they take an additional 1/3 of their max health in damage totalling at least half of their health, if they fail a dc 17 fortitude save. You can only have one creature or object become a bomb, at higher levels, for every level you have, one additional creature or object can be turned into a bomb. If an object or creature affected by this spell dies or, in the case of the object, explodes due to the spells effect that object or creature is completely destroyed, the only thing that can bring it back is a sufficiently powerful God capable of restoring matter, or a wish spell. This means that you cannot revive a creature killed by this spell or restore an item destroyed by this spell.
