Level 1 HazardXP 100
Detect Nature or Dungeoneering DC 19Initiative +3
Attack: Close burst 3 (creatures in burst); +4 vs. Reflex
Hit: 2d6 + 6 damage.
Miss: Half damage.
Effect: The area of the burst becomes difficult terrain.
Special: As soon as the attack fails to recharge, the rockslide is over and does not attack again.
Avoid: A creature that takes damage from the rockslide can use an immediate interrupt to take advantage of natural openings in the slide to avoid damage by making a DC 25 Nature or Dungeoneering check. With a successful check, a creature takes half damage (or no damage if missed).
