What is the real reason why Calca lost the dragon in the third game of RNG vs IG in LPL Finals?

In the third match between RNG and IG in LPL Finals, the real reason why Calca lost Dalong was found, not Casa's mistake, but Dalong!

What's going on here? Let's see: there is nothing wrong with the punishment of the third blind monk!

Blind man 12 level penalty 720 blood. At that time, Dalong still had 672 blood. At this time, he should be able to win Dalong firmly, but it just happened that Dalong was upgraded, adding 125 blood, and there was still 30 blood after the punishment. There is no way. Casa's punishment is very good, but it's a pity that it's not as good as Dalong's upgrade!

So the real reason why RNG lost Dalong is that Dalong didn't upgrade and add blood. There is really no way to do this. Do your best!
