Yep - you are correct; it's Item Revisions.

Gloves of Missile Snaring
Equipped Abilities:
Off-Hand THAC0: -20 penalty
Deflect Arrows: deflects ranged weapons
Requires: 15 Dexterity
Usable by:
Bard
Thief
Monk
Notes: I've drastically improved them while keeping the original concept (which was +2 AC vs. missile weapons). I've made them usable only by bards, monks and thieves (single class only) for balance, technical and concept reasons.
Even SixOfSpades agrees:
" Wait--so the intent is to be a permanent Protection from Missiles, available only to Monks and those using Single Weapon? The effect would be too strong, even if you could perfect the implementation--which might not be feasible. "
Thanks for the help.
Just out of curiosity - Would you have moved the "improved" version to BG1?
