[Gimli]

He suffers from Cha because it ate up 8 starting ability points that IMHO should have been divvied up amongst Str & Dex (and if any was leftover, Con). It makes him weaker as a combatant, period.

"The only benefit I've ever found for being a human is the bonus feat. Of course, having a bonus to wis and cha outweighs this for a monk/paladin."

Humans also have no ECL penalty; they get a bonus skill point at every level, and get 4 bonus points at character creation; and they have no favored class. And I think the multi in question (monk/pali) is a mistake in the first place. Not that I don't like Aasimars - they and the Drow are the only races with a net +4 in ability points. I just think the way you're using their points is unwise and wasteful. This is just my opinion of course.

Dex has nothing to do with unarmed attacks here, so Str is very important. Not only to increase your chances to hit but to up damage. Monks can't take weapon finesse for their unarmed attacks, also they can't focus and/or specialize with unarmed. So the *only* way to bump it with stats is via Str.

No one's saves are great at level 1, but that's no reason to max Cha and take a Paladin level. One of the Monk's strongest points is their great saving throws, so I just don't see why you want to add to them at the expense of his other stats. I would suggest that a pure Human Monk, with a better blend of stats (not only would I not put 8 points into Cha, I would rob from the stat down to a 4 or so) would mop the floor with your Aasimar in a fight. You'd be 2 levels behind him, and your AC, BAB and damage would all be less. Also you have to be lawful good with your build, and evil Monks aren't effected by alot of the alignment-based spells that will be cast his way (such as unholy blight, etc).
