C4/Semtex

So-called “plastic” explosives resemble slabs of wax. Hard and translucent when cold, these explosives warm up when kneaded, and then can be coaxed to take various shapes. The information on the table represents a 1-pound block. Additional blocks can be wired together, increasing the damage and burst radius; each additional block increases the damage by +2d6 and the burst radius by 2 feet, and requires a Demolitions check (DC 15) to link them.

Although the damage statistics on the table represent a 1-pound block, C4 is sold in 4-block packages. The purchase DC given represents a package of 4 blocks.

C4/Semtex requires a detonator to set off. It is considered to be a moderate explosive for the purpose of using a Craft (chemical) check to manufacture it.
