So I've been in AD and randomly hunting, it turns out my hitter when clicking "guard" can actually hit the invisible creatures (and the thrower didn't drink see invisible potion or casted see invisible). Technically, this should be fixed. The reason I mention this is because the hitter on the other hand can't see the creature so can't "attack", to be balanced, the thrower shouldn't be able to have a workaround and attack via clicking "guard"
Anyhow, not complaining, on the contrary, loving the fact that my thrower is awesome :) but just wanted to point it out.
Hope it helps.
All mobs actually can hit from "guard" mode if they're within attack range of the invis character. This is true for NPC mobs as well, and why you're wizzies will sometimes get hit if a mob ends a round near them (I think some of the default AI on melee mobs is to "guard".)
If you have a melee character you had them guard in range of an invis mob, they'd hit it as well. The thing with the thrower is that they're always in range of everything, so they can always attack. I don't think it's a "bug" really, and I'm actually find with the way it works. I certainly wouldn't mind if the found a way to "fix" this so that mobs couldn't attack my wiz unless they also casted see invis.
