After doing some testing with the Sneks Kingdom and their champion. After a champion fight starts you not use any commands at all, Skill commands do not work unless you have it bound to an item /skill will not work along with all chat commands, mod commands, Party commands and Hero commands. Also, for those of us Mods/Admins... make 100% sure you are not in vanish, otherwise, you get stuck in it, the only way to get out of it is to disconnect.
On a side note, The hourly activity bonus should be worked out better. As a player, they get exp per hour. and as staff (at least for mods not sure about others) we get money. I feel as though everyone should get the same reward just at a higher rate. IE Players get 250xp per hour, Mods get 500exp per hour so something along those lines.
Edit: 1 Donors seem to not have the right backpack size, a few others and I have this issue.
I will edit my post with more feedback as I play more.
