Shadow Double Runes (1-2)

HAZARD -1

Stealth +7

Description A cloud of invisible magical sensors in a 10-foot radius surrounds a shadowy 3-foot-diameter rune on the floor.

Disable DC 12 Thievery (trained) to carefully erase the rune without triggering the sensors, Dispel Magic or a spell with the Light trait (1st level; counteract DC 13) to counteract the rune

Create Shadow Double (illusion, occult, shadow, visual)

Trigger A creature without the Shadow trait ends its turn in the cloud of magical sensors, and a member of the Onyx Alliance is within 60 feet

Effect This trap casts a minor version of Mirror Image: it creates a single illusory image that swirls about the nearest member of the Onyx Alliance within 60 feet, functioning in all ways as a mirror image cast by that creature. The image remains for 1 minute, or until it is destroyed or the trap is disabled. A creature can have up to three shadow doubles at one time; any additional doubles are instantly destroyed.

Reset The trap resets each night at dusk.
