Guardian Daemon - CR 11 (Large Fiend)

Nestled away in the 1st Edition AD&D Fiend Folio is a potent monster conjured by some to watch over their treasures or lairs. It is a monster I later farmed for XP in Eye of the Beholder 2: Legend of Darkmoon, suffering more than a few close calls as my characters labored to bring the brutes down. Now it can haunt the vaults and halls of your own games. Enjoy!

Variable Resistance: 3/day, when the Daemon would take acid, cold, fire, lightning, poison or thunder damage, it gains resistance to that energy type for 1 hour. This applies to the triggering damage as well as all subsequent damage of that type.

Muliattack: The Daemon makes two claw attacks and a bite attack.

Bite: Melee weapon attack, Reach 5', +8 to hit, one target, Hit: 17 (2d12+4) piercing damage.

Claws: Melee weapon attack, Reach 5', +8 to hit, one target, Hit: 11 (2d6+4) slashing damage, and moves target to a square it can see within 1d4 x 5' of its current position (D.C. 16 Strength or Dexterity check negates this move). Hit Natural 15+: Target must make a D.C. 16 Strength or Dexterity check or also be knocked prone.

Daemonfire (Recharge 5-6; Automatically when Daemon first reaches half total hit points): The Daemon breathes a 30' cone of green, blue and black flame, which inflicts  24 (7d6)  fire, 24 (7d6)  cold and 24 (7d6) force damage (D.C. 18 Dexterity save for half). Failed Save 4+: Target is also stunned until they make a D.C. 18 Constitution save (they may do this at the end of their turns).

No omelette for you!!!
