I've got a max insightful staff head for sale (+5 energy), and max vamp bow string (5/-1). I need to clear some storage space, so if you buy my staffhead I'll give you the added bonus of halloween items! (9 witches brew, 9 absinthe, 9 squash serum, and 9-teen ghost in a box!)

Insightful sold, still got the vamp string.
