Welcome again to Masters and Minions, where I strive to give you interesting NPCs and encounters that can be placed easily into your game. This week is Ice Week, and this week’s encounter is with the yeti sorcerer, Frostfiend.
After being exiled from his tribe, Frostfiend has been preying upon several of the villages at the foot of the mountain. Frostfiend uses his sorcerous powers to avoid detection until he is close enough to attack his prey in melee. He uses floating disk to carry large or heavy prey back to his cave, which he wards daily with alarm.
SPECIAL ABILITIES
Cold (Su)
  A yeti's body  generates intense cold, dealing 1d6 points of cold damage to any creature that  contacts it with a natural attack or unarmed strike, or whenever it hits a foe  with its claws or rend attack. 
Frightful Gaze (Su)
  Creatures within 30 feet that meet a yeti's gaze must  succeed on a DC 21 Will save or stand paralyzed in fear for 1 round. This is a  mind-affecting fear paralysis effect. A creature that successfully saves cannot  be affected again by the frightful gaze of that yeti for 1 day. The save DC is  Charisma-based.
