The time mentioned for the respawn of the boss is the average time of their respawn in the gameplay. It is strongly advised that players do not leave the boss’s location or area. If you wait for the boss to respawn, you can defeat him and also get some potential rewards.
What players must remember is that they must continue to attack the bosses until they die or fall. You can easily find the bosses’ locations, attack them, and get wonderful rewards.
