A room divided into 4 sections, allowing 4 different teams to practice all at once. It is filled with dummies, when one dummy is burned, frozen, etc. a new one pops up. After all, those big chunk of rocks, or that big splash, or those fireballs won't follow the opponent.

Weapon Play
If you own a sword, a axe, etc. you can also practice hitting the dummies with those too. That's what I call sword play. mrgreen
Then again, fists and feet count as weapons, right?
