Sand Whirlwind

COMPLEX HAZARD 14

Stealth +23 (trained)

Description Buffeting winds swirl sharp grains of sand about the room.

Disable Religion (expert) to state an Iroran koan about being complete only upon recognizing one's incompleteness, or DC 41 Occultism (master) to create a ward against future hauntings

AC 10

Sand Vacuum

Trigger A creature attempts to leave the chamber

Effect A powerful wind pulls the creature back into the room. The triggering creature must attempt a DC 39 Fortitude save. The haunt can use this reaction any number of times per round, but only once per creature that tries to leave the room. The haunt then rolls initiative, if it hasn't already.

Critical Success The creature is unaffected.

Success The creature is pulled back 10 feet into the room.

Failure The creature is pulled back 15 feet into the room and is Blinded for 1 round.

Critical Failure The creature is pulled back 15 feet into the room and is blinded for 1 minute.

Routine (1 action) The haunt's violent winds savagely buffet everyone in the room, dealing 6d10+30 bludgeoning damage to living creatures (DC 34 basic Reflex). On a critically failed save, a creature is also Blinded for 1 minute.

Reset The haunt deactivates after 1 minute and re-forms after 1 hour. The haunt is disabled and doesn't re-form if at least two creatures spend 1 minute to create an image with the sand. Creating the image requires a successful DC 30 Crafting or DC 30 Thievery check.
