Blast disks were employed by many of the nations, especially Aundair. In fact, many battlefields still contain unexploded blast disks — a fact that makes the exploration of the past a very dangerous thing.

This jet-black, 8-inch-diameter plate bears a bas relief humanoid skull surrounded by runes and sigils. Its other side is perfectly smooth and flat.
A blast disk can be set to explode through proximity or on a timer. In either case, when the disk activates it explodes, destroying the blast disk and dealing 5d6 points of fire damage to all creatures and objects within 10 feet (Reflex DC 14 half).
If set to explode through proximity, a blast disk must be set down in a square on the battlefield. The next creature of Small or larger size to enter that square (either on the ground or airborne within 5 feet) sets off the blast disk. That creature receives a –2 penalty on the save against the blast.
A blast disk can also be set to automatically explode up to 10 rounds after placement.
A character who has trapfinding can find (Search DC 28) and disable (Disable Device DC 28) a blast disk.
