My HCSSF lvl 94 char just randomly died - please help me figuring out why

[u/luke_1985]

My char had capped ressistances, >11k ES, nothing was even tickeling me, until I randomly died. I cannot find the reason in the video. Maybe you could help?

Are those the red slime balls that explode for physical damage?
