I'm running a fey Hexblade in a 4e game and have been thinking of taking the Wand or Rod expertise feat. Since Rods tend to rely on cursing powers I don't have, and wands seem to rely on wizards spells as far as I've seen, I'm not sure which benefits me more. Which would be the best choice?
Alternatively, what are some good wands or rods that might work well with fire, lightening, or, particularly, cold, powers? If there's a "killer app" wand or rod, that might make the choice easy.
