Vagrants Keep is a small town that players can buy stuff and sell stuff themselves.It sells a variety of weapons,armour,daggers,shields.The prices are very reasonable it never goes above 50k col.For people who doesn't sell anything and just depend on col dropped for enemies,yes it will be hard to obtain a high amount of col unless you have been saving for ages.The weapons there are not exactly great but far from bad at the same time.The weapons here a supposed to be worst than rare drops from enemies,mini bosses and bosses.
