The Forever War Chronicles
This small satchel charge is designed to bring down buildings, fortifications or destroy vehicles entirely. Setting the device takes a (Demolitions DC 20) check and can be set to explode up to fifteen minutes later by way of a small timer set within its surface which must be wound up. Once detonated, the satchel charge inflicts 20D6 Damage on the target. Note: This device ignores the hardness of doors, walls and virtually any other kind of material. Typical Cost: 22,000 Courtly.
