This is an idea for the Death level 98 spell. I don't have damage, but I do have animation and basic spell-collecting quest lines. Quest-Line:
Dworgyn will call you into Nightside, where he tells you you are ready to learn your newest spell, the Werewolf. He sends you to Grizzleheim, to meet with the King of Bears. You talk to the king, where he tells you that the Werewolf is the grandfather of all the wolves in Grizzleheim. You're sent back to Dworgyn to tell him what you know. Dworgyn sends you to talk to Mortis, to prepare the ingredients to cast the spell. First, Mortis sends you to fight Polytemius(?) the Moon boss in the Trial of the Spheres, to collect a Moonstone. Next, you're sent to Wintertusk, to collect a claw from a wolf in Austrilund (I forget the name). Finally, Mortis sends you to fight Morgund Blackcloak, a Fire-School raven (with Death Mastery-only uses Death-School Spells) who hoards a vial of poison from a Werewolf's fang. To conjure the spell, you have to go to a cliff in Mirkholm Keep (inside the Wolf Palace, near the Yardbird). The Werewolf appears and says, "Necromancer. You have done well in your knowledge of this Dark Magic. You may call me when you wish, to aid you in eradicating the Shadow."
Spell Animation: Open to the moon (with the face from Orthrus), and hear an Orthrus howl in the distance as we pan out to a cliff with Dead Briar Trees (see Bazaar-Plant Life). A furry black claw appears on the edge of the cliff as the Werewolf (looking like a black wolf) pulls itself up. He howls an answer to the Orthrus, then growls at your opponent(s). The Werewolf leaps at the enemies one by one, and slashes at them with his claws, like Forest Lord.
I like the idea of a Werewolf spell for 's new attack spell. I think the animation sounds good but it should deviate a little from the orthrus and forest lord spells. I think an AOE drain that heals teammates a little would kinda cool. Maybe overpowered. I wouldn't mind seeing get an AOE spell although most may say they don't need it. A high hitting single attack then would be good. No infection side effect, add a plague of some type. One of the two would be good. I like your Werewolf spell name and idea. Well done : )
