Felid (Enemies)
Felid Hunter: (natural) Invisible until you come within 3 spaces of where it is hiding (usually a plant, fungus or statue); Jump Attacks you, then self-berserks. When the berserk ends they blink away, and re-camouflage when they leave LoS.
Felid Debilitator: (natural) Focuses on Hexes. Single spell unique to them. {Confuse, Jinx, Slow, (Random 'Bolt' or 'Throw' spell; depends on placement), esc: Blink Away}. Jinx: Makes you 'unlucky'. [25% chance of failing at anything, similar to trips in shallow, water, but checked on moves, and magic as well as attacks.] doesn't check MR; instead affect you 50% of the time regardless of everything else.
Felid Summoner: (natural) Specific summons would depend on placement. Has blink away as both a normal slot and an escape slot. Unlike other summoners, constantly runs away; summoning to keep you from following it. Theoretical examples:
Stronger: {S. Natural, S. Demon, Blink Away, Blink Away, Haste, esc. Blink Away} (S. Natural being a summon similar to an enemy version of Box of Beasts)
Weaker: {S.Mammals, Blink Away, Call Imp, Cantrip, Cantrip, esc. Blink Away}
Mummified Felid: (undead) {Jinx, B.Draining, S.Torment, Heal Undead, Summon Undead, esc. Banishment} Heal Undead: heals all undead in LoS, including self; strength varies with HD. Uses a Kiku wrath tick as a death curse.
Conjurer and Necromancer variants also recommended and possible, but all I can think of in those isn't as -unique- as the aforementioned; probably being similar to an existing Orc, Spriggan, or Deep Elf depending on the placement and level.
