They are a bit pricey, but you can buy as many as you like. gain on any character who uses it for one hour. Once you beat Ashes of Malmouth, that character can purchase Potions at one of the Steelcap District Vendors that increases Exp. This can be put in your Stash and used to rush other characters to higher status levels.
Once you reach Revered status with a Faction, you can purchase an item that will increase the Faction exp. Sorry in advance if you already know all this stuff: Originally posted by TheEvilFatGuy:Don't know if this would help you any, but there are a few already in game things available.
