I'm curious as to if it is possible to alter them in any way, beyond using the level up screen.

I had hoped to change mine, at the time of level up forgot, and was just curious if this was possible.

Nothing detrimental to the server, or RP, or anything, but was just curious.

As far as I know, this isn't even possible with LETO; if someone who actually uses the program regularly knows that it is possible, please chime in (even if you're not a DM).

ScottyB please chime in (even if you're not a DM).

It's possible, through various IG means And Leto.
