Correct, no weapons.

This year there is a full tank(?) of water under the arena so the sand level (or whatever it is this year) is able to cover or uncover the water. In fights with water based Wesen, the arena will be half and half, but if like a Naiad and a Wasser Zahne face off, then it will be all water.
