[ToL Mission] Aten Ha Ra - Critical Damage Taken

I got killed in the mission by a critical hit. Is that supposed to happen?

Sat Dec 11 16:33:55 2021] You have taken 585585 damage from Shredding Claws. (Critical)

The rest of the hits were ok:

Sat Dec 11 16:50:26 2021] You have taken 91092 damage from Shredding Claws by a smirking guardian.

however the critical killed me.

Thanks

Tlail
