As imbued powers fade and are re-imbued, it can easily become absolutely uncertain where is which power, and more importantly, where is no power at all, as when power fades, it is not reflected on item\'s name as when you imbue it. Of course it is possible to identify equipped items one by one but it takes quite a long time and also consumes considerable amount of mana. So conjurers developed a spell to get quick overview which power is where, and also feel whether these powers are going to disappear soon.
