You've learned how to make explosives from miscellaneous mechanical parts. You can spend one hour of your time while resting to create a batch of one of two types of bombs. You can only create one batch per long rest.

Small Bomb

Thrown (60) -- 5ft radius explosion -- Each creature within the radius must succeed a DC 13 Dexterity saving throw, taking 3d6 bludgeoning damage on a failed save or half as much on a successful save. 

The number of small bombs produced in a single batch equals your Intelligence modifier (minimum of 1).

Large Bomb

Must be placed; cannot be thrown -- Siege equipment (double damage to structures) -- 20ft radius explosion -- Each creature within the radius must succeed a DC 16 Dexterity saving throw, taking 3d10 bludgeoning damage on a failed save or half as much damage on a successful save. 

The number of large bombs produced in a single batch equals half your Intelligence modifier rounded down (minimum of 1).
