I have it on my bludge rend one and on my CB bludge wand, the CB wand works amazing on both Vaeshok for the society quests as well as the undead bosses for summoning T'huunn as well as a few other undead bosses, if I get 2 crits on Vaeshok, he is pretty much dead (I have gotten 2 crits in a row, it was awesome).
I also suggest adding this after you have 10 tinked your weapon/bow/Wand, as it is a no fail addition, and there is nothing worse than blowing up a slayer wand after it has been added on due to a failed tink.
