One-on-one hero needs high recovery, high shield value, high monster killing efficiency, and certain conditions can be met.
For example, blind monks, Berserker, the arms of magic snakes, the goddess of storms, werewolves and other equipment can be killed alone when they reach the corresponding level.
In the late stage, the dog head, the undead and the small mage can also easily take away the dragon after 200 minutes.
