Right-clicking on an item in my inventory equips it instead of using this skill on it. No other way to use this skill AFAIK.
That's because the item you're trying it on isn't an Artifact and thus, cannot be sent to the museum. Although why it equips the item instead (right-clicking on gear doesn't NORMALLY equip it, although maybe it should) is a bit of a mystery. If the item isn't *random name* the *random noun*, then you can't use IBiaM. The exception to this are certain bugged items (Armored Vizier's Robe, Green Armor) that count as artifacts if they have the extra stats but never receive the "special" name.
Right clicking on gear DOES equip it. The only time it doesn't is: - If you're using two weapons and right click a weapon. - If you're using two shields and right click a shield. - You right click a crossbow.
Hrm, I'll have to experiment. I swear there's been a bunch of times where I right-clicked and nothing happened, but it was probably because of one of the reasons you listed.
Yeah. I can understand the first two reasons, but the third is a total oversight. Works on all armor, though. OH, forgot one. - If you have two rings equipped and right click a ring. Same issue.
