Multiclass characters can only use multiclass kits. But in Demihumans of the Realms (and probably in mid-90s 2e in general) a multiclassed character may have one kit, which can be applied to one of the character's classes.
Thieves have Thieving Skill Base Scores.
All other characters have Detect Noise 20% (+race modifiers) and use 40% for limited Climb Walls (+race modifiers and simplified armor penalties). They also use Surprise rules to resolve stealth. I'm ok with that.
