Enemy targets called Husk Balls will periodically spawn in the arena. After taking damage, they will bounce back and forth across the field. Agents can make good use of this characteristic to defeat powerful enemies.
Note: The next wave will only spawn after all Husk Balls in the arena have been eliminated.
Ether Power Canister

Note: The next wave will only spawn after all Ether Power Canisters on the field have been used.
