Multiclassing/Dipping Shame

[Tanarii]

And still i have no problem whatsoever of talking about necromancers in classless systems and people having a good grasp what that means. I mean, i literally did that. And people know that the character will have an assortment of whatever the system has in terms of undead mastery, ghost summoning and death magic and that a big chunk of his points have gone there.

You left out "psychic who talks to the dead, but otherwise has no other special powers".

Because "Necromancer" is a word that will be both world and system specific. It's not a word that that has very specific meaning, other than some kind of supernatural power related to the dead.

Something doesn't need a class to be understood. If i use D&D and say my character is a horse-archer, people understand that as well without needing some horse-archer class.

Someone who is useless as soon as the adventure goes into urban, underground, or non-plains natural terrain?
