Singe: keep or sell?

[Reincar]

Hi, I just got singe out of a chest and I have no clue whether I should keep it or sell it. As of right now I really only have wrathjaw and fantasma to use and I don't know if the gold would be more beneficial or not.

Could someone list the pros and con's of singe for me? Thanks in advance.

Edit: forgot that I also have courage, if that makes a difference.
