And if you are playing AD&D, what races can become an 18th level magic user/cleric?Monster Manual wrote:Liches were formerly ultra powerful magic-users or magic-user/clerics of not less than 18th level of magic-use.
Unless we are counting a dual-classed human who might be cleric 10/magic user 18 the answer is "none that we know of". (I had a quick check of H4 and it uses the same single / for both the multi-class pregen and the dual class pregen characters.)
I had thought that the Dungeoneer's Survival Guide introduced liches of a forgotten race who could also be just clerics, but checking I see that I am wrong ("The skeletons include those of drow, duergar, svirfneblin, and derro. In fact, other subterranean creatures who left no skeletons-pech, cloakers, and illithids-also fought and died for control of these caverns." and "Each treasure house is guarded by a veritable army of undead, commanded by a lich of 18-27th level (17+ld10). Twenty percent of the liches are magic user/clerics and the other 80% are only magic-users") but with the possible exception of drow, I don't think any of these races could be a 27 mu/cleric either and humans are not listed, so perhaps some unknwon race is the answer.
So, what race(s) gave rise to the magic-user/cleric liches found in AD&D? Any thoughts?
