I believe the game needs more people named Amos. Everyone should make an Amos, or two, or three! BUT!!!! If you have the desire to ever make more than one character who goes by the name Amos, it's important to understand what I'm about to write here.
The game only allows one character on an account named Amos (or any other specific name, it won't allow duplicate names). It's important to use some name other than "Amos" during character generation and then when entering the game, add the keyword "Amos" and use that as a second name. If there is already a character named "Amos" on the account, IIRC the game DOES NOT allow adding "Amos" as a keyword. So only "Amos" as an added keyword and never in character generation, that is unless you only want one character who goes by the name "Amos".
