Gjallahorn because for people who are lvl 33 like me and don't have it (witch is sad) should be able to get the gjallerhorn so that they can get better and help more in Crota's End, Vault of Glass, and Prison of Elders, ect and another thing he should sell is Last word because everyone has it or they should if they are lvl 30 and above (I don't have it) if u read these and if he does end up selling the Gjallerhorn or Last Word thank you =^-^=
