Mask Summoning Rune

COMPLEX HAZARD 16
Stealth +32 (master)
Description A cloud of invisible sensors in a 10-foot-radius surrounds an invisible floor rune.

Disable DC 40 Acrobatics to approach a rune without triggering it followed by DC 42 Thievery (master) to erase the rune, or Dispel Magic (8th rank, counteract DC 34) to counteract the rune.


Summon Mask (divine)
Trigger A creature enters the cloud of magical sensors

Effect The rune causes a chain reaction throughout the room, causing all remaining active summoning runes in area D2 to summon a Mask of Gray Master. The masks roll initiative and remain for 12 rounds, after which the effect ends and any remaining Masks disappear. A Mask also disappears if someone disables its linked trap before the duration expires. The Mask can use 3 actions each round and can use reactions, unlike most summoned creatures.
Reset The trap resets each day at dawn.
