The Elder Scrolls Online: Tamriel Unlimited

The bosses themselves walk around the center of the area, respawn every 10 minutes, after killing 1 boss of the area, 2 will spawn. After killing 2, 1 will spawn. You just need to poke the boss once (you can sit on the courts next to the boss, and when the enemy farming alliance comes running, hit the boss a couple of times when he has about 10% and try to escape, this is enough for him to count, the main thing is not to die before the boss).
