Duration of some powers can get quite long, and sometimes it may be desirable to get rid of an imbued power so that you can imbue another one in its place, as creating completely new item is not a choice at the moment (for example when you have multi-power item with several powers you want to preserve, and/or don\'t want to spend all the mana needed to recast everything). For such a situation, there is lesser purge spell. Just select an item and power you want to clear, and here you go.
