Hune carried a unique intelligent Staff of Withering. A few times each day it can inflict Necrotic damage after a successful melee attack.
Sakura no kaze attempted to investigate the staff after it was recovered and these are his findings. There is an ancient glyph ward edged into the base of the staff that is fairly artistically designed. However Sakura is able to decipher that is says Agrach Dyrr in Undercommon. It is assumed to be the mark of the maker of this item.
With regards to the sentience of the staff, it does not communicate with Sakura and Sakura believes that it might require bonding the staff to properly communicate with the staff. However, Sakura isn't able to bond the staff even if he wanted to because he senses that the staff and the bonding of the item requires a different type of magic.
