Dying After Boss FIghts

Same as POE1

Can we just like.. stop all damage effects after a boss fight is over? Is there any need for this to be a thing?

Also, can anyone explain what I just died to fighting the sentinels in trial of the sekhemas?

The clip I have ended just as the shards hit me, so you don't see my death, but it looks like 2 shards hit me within a split second. First one almost killed me, second one finished me off. What kind of insane damage are these things doing? And why is it happening after the fight?
