If your wand has one charge sell it and buy (or steal
) again - wand will be recharged. I think that from the Irenicus dungeon you can bring about 6 different wands. Wand of Heaven is somewhere in city - I have one. Before chapter 4 I had a few wands of magic missiles, two of cloudkill, 2 or three od ice and fire - it is enough. It is more than I can use
