Well, look, you see, it turns out you also think that a ninja only needs a couple of levels of Death magic – he mainly remains a runner. That is, you won't get a full-fledged Death mage out of him.
Yes, it doesn't matter what they give him there. The main thing is that there will be a combat branch, which is necessary for an assassin. All the usefulness of such an endeavor boils down to getting +3 to speed for a mage-necromancer. His job is to cast spells, not to fight. That is, specifically, I consider the assassin to be a useful class for Death, at least one of the useful ones.
Не стремясь приобщиться к основам пришёл.
В прошлый раз утащил я молитвенный коврик,
Он истерся до дыр, - я за новым пришёл.
