I have a 19th level rogue (3.5e) with a +2 rapier (keen, wounding) that has a wand chamber built into it (Dungeonscape). I use a Wraithstrike wand in the chamber. Questions from the other players and DM have arisen about the use and effectiveness of this wand/weapon combination. Touch attack each attack round? Touch attack every other round? Poor choice of wand for a rogue--use another wand? Do any of you have experience or opinions?
