large shield, boots of avoidance, magical full plate, helm & cloak of balduran, high DEX, you can easily get -15 missile AC. That pretty much means you only get hit by criticals. Normal damage since your wearing a helmet. 1 in 20 hits from 20 kobold commandos = 10 hits in the time it takes to dice-them hand to hand. Anyone with more than 60HP or some healing potions should be fine.

Mages can cast "protection from normal missiles", wonder on over and cast fireball at their lesiure, except most archers worth worrying about use magical missiles. Protection from magical weapons would help here, but thats BG2 only.
