On the tamer:
My mage tamer (120 taming/lore/vet/magery/med/EI) can solo baracoon and mephitis spawns with relative ease. I have trouble killing drakes fast enough to advance reptile spawns and my dragon gets into too much trouble with burning gargoyles to make imps very profitable.
I do undead spawns on my archer (archery/tactics/bushido/chivalry/meditation/healing/anatomy). With mischief maker and a conjurer's trinket, nothing gets close enough to me to hurt me (unless I do it in Deceit) until Neira herself. Then I usually have time to cut most of the bones, only running away if a lich lord or rotten corpse shows up. Note: I only cut the bones if I'm soloing. Even if only one other person is with me, I tend to let the bones go.
I had a necro-tamer, but decided to go pure necromancer instead. But the necro-tamer (taming/lore/necro/SS/magery/then a choice between two of the three, EI/med/vet) is a very powerful spawning template. I rarely see one of those run into trouble, and necromancers kill things very quickly. My version had less taming and lore and I used a beetle/bake or two bakes and could solo anything but the undead (lich lords) or demon (burning gargs or succubi... area effect stinks when there's a ton of enemies on the screen).
