not sure if this is already known since bane is not a new property, but decided to mess around with one of the bow drops. I imbued ssi and hci on it, noting that the "Bane property" added no weight to bow( 0 value) which was nice.However it could not be enhanced(got the already has special property message), not good. Also it could not be powdered and these have low durability to start(mine had 37), nearly dropped to zero, when i was doing about 2-3 generals and a few other spawn in yew. As far as property i only noticed it going off about 1-3 times per general. Though not 100% sure since i was doing in low hundreds and ,when i noticed it going off, it was doing 150-200. This was when general was almost dead so it may have been going off earlier with lower damage.
