AITAH? Invisible Vaal Mob Dropped An Anchor On Me

So... I had just killed Doryani (Stone Citadel) and collected my fragments. Usually, I just bail after that, but today for some unknown stupid reason, I decided to stay and kill more mobs.

Guess I thought that might be fun.

I'm an idiot. I forgot to examine each and every affix on an imprisoned essence mob before I released it...yeah, that was fucking stupid of me. Well, in most cases, you can solve that problem by just playing an OP build--which in my case, I was (temporalis blink + spark + trampletoe + archmage)--but it just so happened that this clever vaal mob had the ability to go stealth & invulnerable on me and pull of a truly heroic play and dropped a titanic anchor on my head for the 1 hit KO.

I'm pretty fucking mad about it, ngl. I'm lvl 97 and now at 35% exp. Had an omen, thank God.

What's my point? Obviously, had to bitch about it. Makes me feel better. Thanks for reading.

P.S. @GGG: That's a pretty shit way to teach your players to "get gud".
