Gargoyles (Lesser Daemon)

While reading a post about imps, it reminded me how cool it was to fight through Gargoyles in UO. They had that demoniac look with big wings and yelled some cool otherworldly words.
It would be awesome if we had a dungeon crawl in Diablo fashion, starting with some lower level skeletons and zombies, and then descending to find higher level imps and gargoyles, and a greater daemon in the end.

My ideas for detailed design:
Technical work: I think the human model and animations would fit just fine, just slap in a good texture and upscale a little bit beyond max player human height. Add some horns, tooth and spikes here and there, create some cool attack / idle / pain voices, equip them with cool polearms and make some of them bare hands magic users which wrestle with sharp claws when at close range (this would require a new animation because regular wrestling animation is a bit pathetic for a daemon).

Fight wise: make two classes, one using some stun in the polearm tree, hitting multiple targets just like players, and another like stated above, unequipped magic user. Both of them may use a fly skill with very long cooldown, with which they move fast but receive a large resistance debuff. Make them be cower and try to flee when close to death, using the fly skill if cooldown allows.

Loot: gargoyle wings, claws, head and skin, which could be used for top end crafting as a premium resource. Maybe create their Halberd type artifact.

Lore: tie them with Ebon Cultist rituals that went wrong. Place some Cultists in the scene only to be slaughtered by the Gargoyles. Make Gargoyles feast on their bodies, giving players a good vantage hit in the beggining of the fight. Add a quest with a sentient Gargoyle that don't want to belong in this dimension so player can either help or kill them.
