Covetous Serpent Ring
The covetous serpent ring +1can be obtained by exhausing the dialogue of the merchant hag Melentia after she relocates from the forest of fallen giants to Majula. This ring causes you to obtain more souls from fallen foes. (Unconfirmed) but there appears to be a second covetous serpents ring in a chest in the lost bastille, unsure if their effects differ or stack.
