BEATERS
Together with the chasers and the keeper you also have 2 beaters on pitch. They are recognized by their black headbands. The beaters use bludgers to help bolster their team's offense and defense.
The bludgers knock people out of the game temporarily. If a player is hit with a live bludger, they must let go of any ball they possess, dismount their broom, and tag one of their own hoops before re-entering play.
There are only three bludgers and four beaters, so it often takes strategic coordination for a team to have control of both bludgers.
Beaters are the only ones allowed to catch a bludger without getting temporarily knocked out of play.
