Mad Bomber

While many “mad bombers” aren’t actually mad, it takes a special kind of crazy to devote one’s life to studying explosives. Most alchemists who specialize in this field are incorrigible pyromaniacs who take great pleasure in burning, blasting, and blowing things up. Mad bombers are always working to improve their bombs’ effectiveness.

Level 2: Blasting Specialty

Your bombs deal double damage to objects and structures.

Level 2: Formula - Shrapnel Bomb

You can augment your bomb’s explosive contents with metal bearings, changing it into a shrapnel bomb. A shrapnel bomb deals piercing damage instead of fire damage, its damage dice are d8s, and it explodes in a 10-foot radius.

Level 6: Timed Demolition

When you prime and throw a bomb, you can set a duration for its detonation, which can be any number of rounds (any increment of 6 seconds) up to 1 minute. The bomb detonates at the end of your turn after this duration. If a creature is in the area of more than one bomb’s blast radius simultaneously, the creature is only affected by one of the bombs of your choice.

Level 10: Blast Shield

You have developed an elemental plating to protect you from hazardous energies. You gain resistance to your choice of acid, cold, fire, lightning, or thunder damage and can change your selection whenever you finish a long rest.

Level 18: Formula - Black Powder Bomb

You can replace your bomb’s explosive contents with a charge of black powder, changing it into a dreaded black powder bomb. A black powder bomb’s damage dice are d12s.
