Bomb Properties

Bombs are thrown weapons and take 1 turn to explode. You can extend the time it takes for a bomb to explode by adding a longer fuze. You can also bundle the bomb to create a bigger bomb. When you bundle you add 1 damage dice per bomb. It takes a bouns action per bomb.

Duds. Whenever you make an attack roll with a bomb, and the original dice roll is equal to or lower than the bomb’s Dud score, the bomb doesn’t explode. You can later collect the thrown bomb and fix it. Repairs take 1 hour. To repair your bomb you must make a successful Tinker’s Tools check (DC equal to 8 + Dud score) and an investigation check. If your tinker’s check fails, the bomb is faulty and must be mended at a quarter of the cost of the bomb. If your investigation check fails the bomb explodes in your face. Creatures who use a bomb without being proficient increase the weapon’s Dud score by 1.
