[Autotune]

Necro.

Necro heal + bard songs.

Bard song + lich.

It's just too good of a combo.

For some reason, the only downside of this compared to an enchanter is, I think and could be wrong, but you can't twitch a bard (or maybe clarity doesn't work on a bard... idk, for some reason I'm thinking one of these is right). If necros can, then there is no downside to choosing a necro over an enchanter as a duo partner really.
