Keystone Trap

Hazard 7 (unique) — mechanical, trap

Pre-Remaster content. May include legacy alignment.

A 5-foot-square metal vault covered with knobs lies concealed within a stone block. A lever on the stone block slides the vault into view. When the vault is exposed-whether it's slid out or whether the stone is smashed open-the trap activates.

Abilities

Exposed Vault
Electrify — The metal vault crackles with electricity. In air, this would damage only creatures touching it; in water, the trap deals 2d8 electricity damage to all creatures in a 10-foot emanation (DC 25 Fortitude).
Launch Darts — The vault fires a stream of poisoned darts. The trap attacks all creatures in a 30-foot line with its poison dart spray Strike; roll to determine the line's direction. These Strikes don't have a multiple attack penalty.
Spin — The vault spins quickly for 1 round. While it Spins, checks to disable the trap have a -2 circumstance penalty, and it Launches Darts at all creatures within 30 feet of it, rather than in a line.
