World boss reward

i wouldn't mind receiving a reward for those who manage to land the final hit on world boss.

I got the final hit on a couple of them so far, and I did get a higher amount of points than usual.
Maybe that's the reward?

well any monster or enemy gets weaker when they have less hp/troops count. It applies to world bosses too lol. So their attack damage would be low enough for some of your troops to take.
