1 = 10 - 15k (just for the base stormbow) ... for someone who wants the skin and that damage modifier, and doesnt care about the req
2 = expert salvage and hope for steel ingots ... or merchant it as Omeriko suggests ... that's a 3-profession item, and fairly useless as such, since the one of the mods will always be wasted. If the requirement was water, and the recharge and casting time mods were also water (even with those non-max values), that wand would be worth around 500k, but it aint ... we can always dream eh?
3 = domination staff with 8% casting time and 20% recharge on inspiration? no prefix, useless suffix ... i'm not sure 20k is low enough, i'ld say 5 - 10k
