Are you allowed to have two accounts?
 

I I was wondering would it be against the rules to have a 2nd account so you can sometimes buff your main but not play together sort of thing? then just log out or possibly just afk one character for xp?

You may have multiple separate accounts, but you may only log a single account character on at a time. You may not "2 box" ever. Using an IP exemption to 2 box, using a cell phone connection + standard internet, or any iteration of this, all will get your accounts and IP addresses banned with no leniency. The GMs look for actions which seem like 2 boxing and have specific ways to test for it. It's also common for suspicious activity to be reported by the community who is avidly against it.

I I was wondering would it be against the rules to have a 2nd account --- this is fine

so you can sometimes buff your main but not play together sort of thing? --- This is BANABLE

or possibly just afk one character for xp? --- This is BANABLE

For a buff bot,there's no rule against having friends log in your other characters for a few mins
You can even have someone login and afk while you XP on one of them
You just can't do this all yourself.

literally everyone is boxing on these servers, hope this helps

I love how each answer got slightly more lenient. Lol.

Not everyone, but I do see, have experienced, your point.

You really should only ever have 1 char per account.

Just in case.

If you have more than 1 character per account and a character needs a rez, just remember that timer ticks down as long as that account is logged into the game.

For that reason among others its no bad thing to set up a new one for each character you make :)

Also, given how it currently works you can ask a friend to log onto your account, e.g. someone could res you using your cleric alt.
