Undead are totally awesome for leveling.
Pole-maces are TERRIBLE because they just miss all the time.  Get a normal old steel staff enchanted, it'll save you so much time.  Yeah, I said staff.  Go in the front row, nothing does any damage before level 15-20 anyway and besides, you have a healing spell.  There's also an excellent place for lower levels with NPCs that take extra damage from blunt, so.... yeah.  Anyone who isn't a lightie should be leveling there, and lighties should be murdering undead with cure light and getting so much XP it's obscene.  Cure light a NPC to death, sleep until the tick passes, lather rinse repeat.  That will give you almost twice as much experience for time spent than casting spells until you go out of mana and then sleeping until you get to 100% mana again.  Besides, it's good practice for enchanting later.  After you get flamestrike, ask around for where to find grouped NPCs near your level (or explore around via the areas command), and after you get spear of faith, just laugh your way to GM.

That's a priest with distant charisma that I pushed past Master 4 including induction RP in less than 50 hours, and the rest of the time I've spent playing him was because he's A) a fun alt and B) to powerlevel an elf warlock to GM in 13 hours, taking the record for leveling to GM by a landslide, and C) enchanting an entire suit of armor/jewelry to reasonably high quality armor.
It's not so bad to level priests, it's just different!  You can do it!
