"Idol, have you figured out why they're not attacking them?" the Little Pet Elf nervously asked. "What if they steal the first kill?"
Li Yao calmly continued dealing damage as he replied, "Now, the boss's health has dropped below 20%. Even if they deliver the final blow, the announcement for the first kill will still be credited to us."
"Oh, I see," the Little Pet Elf said, coming to a realization.
In the mechanics of this ancient game, if two or more teams are fighting over a boss, the team that deals the most damage is credited with the first kill.
Moreover, it's rare for two teams in this ancient game to engage a boss when it has a lot of health. This is due to the game mechanics; as the number of players increases, the boss's health soars in response.
The consequence of this is usually a team wipe. After all, the bosses in this ancient game are incredibly tough.
