[Dorito]

To get a familiar inside BH simply summon a familiar of your choice, logout, go into a F2P BH crater, logout, login on a P2P BH world, and walla, you now have a familiar inside BH.

To bring in items like coins, or noted items, or anything that you normally can't bring in, simply summon a BoB (Beast of Burden), give him your items, then logout, go to F2P world, login, go inside crater, logout, go to a P2P BH world and login, and again, now you have successfully smuggled items into BH that you normally couldn't have.

Have fun!
