Obsidian Temple has no heroes and normal modes, only 18 people and 25 people, the other 3+ 1 people are dragons, 10 people are black dragons and 25 people are twilight dragons.

10 people 3+ 1 BOSS of Heiyao Temple seems to have a life of 360W W. It is almost enough to kill the BOSS with a brush of 30-90, as long as DPS is enough.

Recommend level 90, and then it is safer to go after the hero graduates.
