Boss Challenge

Boss Challenges contain Overlord Echoes and provide rewards for defeating them.
Once they have been defeated, players can use Waveplate x60 to claim their rewards. All bosses respawn 2 minutes after they were first loaded and they will respawn even if the player is nearby or in a menu. The option to claim rewards will also disappear after the boss respawns. The exact time remaining until the boss respawns can be seen by clicking on the boss on the map.
