Conjure Bomb

When you cast this spell you summon a Bomb (found in the adventuring gear section), lit or unlit, at a point you choose within range. Each creature within 5 feet of that point must succeed on a DC 12 Dexterity saving throw or take 3d6 fire damage. If lit the bomb explodes immediately. The bombs are also able to damage and destroy structures. If the bombs do not explode before the duration ends or the spell is cast again the unused bombs instantly explode.
