Party Level Difference

[Baler]

What is the max level difference between two party members to allow exp gain? Are there any penalties for grouping a higher level with a lower level and if so what are they?

I read on the offical eq forums that the higher level player has to be within half their level with the lower level. (level 30 and level 15 for example) I am not sure if this is accurate to p99 however.

I searched the wiki and the forums for this and I could not find anything. Perhaps I missed it.

Thank you for your time.
