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. ### Blasting Specialty (Level 2) Starting when you choose this field of study at 2nd level, your bombs deal double damage to objects and structures. ### Formula: Shrapnel Bomb (Level 2) At 2nd level, you can create shrapnel bombs. By augmenting your bomb's explosive reagent with metal bearings, you can change it into a shrapnel bomb. A shrapnel bomb deals piercing damage instead of fire damage, has `d8` damage dice, and explodes in a 10-foot radius. ### Timed Demolition (Level 6) At 6th level, you've learned how to set bombs to explode on a delay. When you take the Use an Object action to prime a bomb and throw it, you can set a duration for its detonation, which can be any number of rounds (any increment of 6 seconds) up to one minute. Following this duration, the bomb detonates at the end of your turn. ### Blast Shield (Level 10) Starting at 10th level, you have developed an elemental plating to protect you from hazardous energies. You gain resistance to your choice of acid, cold, fire, or lightning damage and can change your selection whenever you finish a long rest. ### Formula: Black Powder Bomb (Level 18) Beginning at 18th level, you can craft the dreaded black powder bombs. By replacing your bomb's explosive reagent with a charge of black powder, you can change it into a black powder bomb. A black powder bomb has `d12` damage dice.
