Noob accounts with ONLY scythes are worth 10-15m. Scythes and bunny ears, however, are worth 30-40m on a NOOB account. Especially on an account with low defense, meaning lower than 45, as they can easily be made into zerkers. If you want ONE defense, expect alot more, and having a HARD time finding your account- even more so from a trusted dealer.
