Trigger The vault is exposed --- Effect The vault makes a poison dart spray Strike at a random creature within 30 feet. The trap then rolls initiative.
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).
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 1d8 to determine the line's direction. These Strikes don't have a multiple attack penalty.
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.
Description
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.
