I've done this quest twice in the last 48 or so hours, mostly solo with a 70 Necro =)
Basically, just kill any of the level 60-65 mobs near the zone into Devastation from East Freeport.
You're looking for no drop items. Wurine paws from werewolves, Kobold paws from Kobold model NPC's, Bloody Orc Heads from Orc/Goblin NPC's.
Once you get 4 of one kind of no drop item, head to Sverag. Hail the NPC behind the destructable wall right after zone in, and hope he's not an Orc if you have 4 Orc Heads, hope he's not a Kobold if you have 4 Kobold paws, etc.
As long as you have 4 items from a mob that isn't the placeholder NPC at that time, you can finish the quest.
Hail mob, select corresponding task that goes along with the 4 no drop items you have, follow prompts, get spell.
Easy stuff, I'm about to pass out right now cuz I'm so tired, so leave questions if I left anything out.
