While you were banned, Ice and the admins came up with new rules and such for the gym battles, due to complaints.
Basically, it was you can do whatever and it's max rules requirement.
I used to say, axes only, but then had to change it to "stone weapon" or lower, I.E. you can come with a swords, axe, or unarmed. Same with bows, if you can fight with a bow, you are allowed to fight with your fists, or a flower, or a shovel, if bows were the "max" you could use.
You can ask Ice, but that is what it is atm.
EDIT: Fuchsia is a use anything, armor up to iron (No enchants on anything, pots or dogs etc.) gym, and most are open too, but I'm not sure on all of them.
