Well, one of the reasons I called the sorcerer/monk an ultimate self-reliant character is due to the monk's character class. ( i personally consider the monk to be among one of the best classes. But the monk never need to repair armor or weapons, eventually gains immunity to disease, poisons, gains spell resistance, doesn't age physical wise, can speak with any chracater, can heal him or herself, move at an incredible rate among with many other unique physical abilities.
the sorcerer was added in because the not great neccessity of a spellbook (though scrolls are handy sometimes, i admit). I sort of was thinking that the monk made up for the clerical side, not to any impressive extent of course.
Also, switch out some things like quivering palm and stunning fist with some other feats that boost the save. Buy a ring of Sustenance to balance out the need to ever eat and the sorcerer
s familiar can take turn at watches with you since you only have an 4 hour need for sleep andyou have the ultimate character. Goes anywhere, travels anyplace, does not need upkeep of food, water, weapons, etc etc. Also, his attacks add in some unique punches due to spells mixed in with his attacks.
there, taht should clarify the character a bit further.
But i suppose the cleric isn't too shabby either.
