I'm having a hard time seeing the problem here. The monk spends two turns in combat (unless they have prep time for short duration buffs) casting shield and reduce person, has taken 3 levels in a class solely to be able to do this, and dealsdamage (1d6 + str bonus, which is at -2 because of reduce person) in order to be unhittable. Is that not totally OK?
In my pathfinder game i have a sorceror who does the same, he spends most of the combat becoming untouchable. Once in a while i send a big baddie after him, to indulge him and make him feel like he is contributing, but overall he'd be a lot more effective if he would just cast... well offensive spells.
Yup, I don't see the problem either.
She's a teflon monk as has been referred to upthread. She's not much else, though. Imagine a party made up of a bunch of her--would they fight at level? I rather think not.
