Pat, Klaatu is talking about D&D Adventurers League , which is essentially playing the same character without necessarily having the same GM every session. He's not talking about making a custom sheet. Klaatu, there is no way to build a character offline, however you can create your own campaign solely for creating your own character. The Character Vault feature would also let you save a copy of the character from your "I just wanna build my character" campaign, and export it into someone else's campaign you're a player in (if the GM enables Character Vault imports). Note that in order to export the character into a game, either you need a Plus (or Pro) subscription, or the campaign creator of the campaign you're exporting into needs a subscription, or the campaign needs to be using a Marketplace Module with All Access Vault Enabled.
