Wand of Enervation rolls 2d4 when used by Sorcerer or Wizard (doesn't register their Arcane skill; didn't test with Bard).

(should roll 1d4+4 instead)

This has been happening to me as well, sorcerer

It's a "known issue" much (redundantly) reported and the Devs "are on it". Try searching for "wand of enervation" and see how many hits you get. When it'll make it into a patch is anybody's guess. But it seems that bugs that affect a single item (especially a rare/reward item) are very far down the prioritisation.
