Sand Blast Trap (CR 3)
The sand shifts along these wind swept dunes.
Type: magical; Perception DC 27; Disable Device 27
Trigger location; Reset None
A strong blast of wind stirs up the sand, strong enough to score flesh. Sand Blast (1d6 damage and be knocked prone and blinded for 1 round, sliding 5' to 20' down sand dune, DC 19 Reflex Save negates); multiple targets (all targets in 20' cone)
In addition, such sand blasts add +10 to the DC of any tracking checks, and +2 to the DC of any navigation style checks, due to the changing landscape.
