ye its a lot, me or anyone i no hasnt bought from pus lol... prolly cos its daft prices.
But i guess if its $5 then all will buy and the few how dont we quit
But really its easy to get chit and shell. Chitin drop really fast and getting +6 is really easy +7 you will burn a few.
As for shell you will need a priest and farm DM, drops are fast, you can do it tho its a little slow with 1 priest/ warrior
