According to Inno:
"In Elvenar you can play using as many accounts as you like, even if that is on the same world. Please do note that if you choose to play using multiple accounts, all of our
game rules apply to each of the accounts, without exceptions.
Example: Even though playing with multiple accounts is allowed, it remains forbidden to create or use one or more account(s) as a "push-account" to benefit one or more other account(s)."
Inno's definition of a push account:
"7. Pushing
Operating a “push-account” is forbidden. This is defined as unbalanced routine resource (resources, Knowledge Points etc.) transfers from one account to the next even if involved accounts do not belong to the same player.
It is forbidden to create trades in any form (goods, Knowledge Points etc.) that involve multiple worlds."
