Thank you for making this, makes the game more enjoyable :)

This addon greys out disrupting gear for antimagic characters that have taken, say, Mystical Cunning.

A suggestion: tweak the conditionals so that the "has arcane knowledge" case isn't checked for antimagic characters. That's a simple fix that covers at least some cases that aren't currently handled correctly.

(Ideally, specific arcane abilities would be exempted, but that would be an awful lot more work.)
