Grazing Deer

COMPLEX HAZARD 3
Stealth +10 (expert)
Description A herd of deer exits the woods to investigate the delicious-looking leshys.

Disable Diplomacy (with Wild Empathy) to befriend the deer and convince them that leshys aren't for nibbling, or Intimidation to scare away the deer.

AC 19; Fort +12, Ref +14, Will +6
HP 44 (BT 22) (if the grazing deer take this much damage, they aren't killed, but they do flee into the woods and don't return)

Approach and Taste
Trigger The PCs emerge from the forest's edge

Effect A deer approaches the party and attempts a nibble Strike against a randomly determined PC. The grazing deer rolls initiative.
Melee Nibble +12, Damage 2d4+5 bludgeoning
Routine (2 actions) The grazing deer takes one action to move about, and then one action to eagerly nibble at a randomly chosen PC. A character who spends three actions on their turn to Stride can avoid being nibbled by the grazing deer during the hazard's next turn. If all of the PCs do so, attempt a DC 5 flat check-on a success, the party escapes the deer and can proceed onward to Petalbrook, but they become delayed as a result of having to flee the pack of ravenous deer.
