The Spirit Realm

It does rock. I just started playing again and made a new pally on test.

Did ToFS (lots of undead there too), lguk, hole, seb and got to 50 in a week of casualish play.

Pre-Slay there really isn't much of an advantage to exp'ing on undead for Paladins. Quite a different story for clerics, and possibly necros however.

I dunno about that. I can kill undead a hell of a lot faster than I can any other mob, simply by chain nuking.. and it doesn't really affect the mana pool much as long as I've got KEI which is mad regen for 46-50ish. Also Instrument of Nife comes in handy. It doesn't proc all that often, but between the times it does proc and the nukes, undead die 4-5 times faster than live mobs.
