Is it any case that enemy was one with 200% base speed? Those bees are, well, pretty insane.
It was bear with 2K hp.
judging by the sensations it cover 2-3 3-4 tiles for one mine.
Did you try track+movement infusion+zig-zag digging?
No, I met him early and start to teleport away in a bunch of other mobs, this escalated quickly, was killed when Oozemancer-based rare or unique interfered.
I just had no time for zig-zag because he was too fast, and it doesnhelp because he two-shot me. Aslo had Movement Infusion, Phase Door and Teleportation.
There are possibility to get rid of EoR stuff by disabling it in addon menu, but if you planning to use tinkers, obviously it's not an option.
Yeah, disabling and avoiding things like Dark Crypt isn't my cup of tea.
Besides that, t2 zones on insane+ are considered as high difficulty spike.
I saw somebody called them as most dangerous part of the game.
Maybe it's you that sucks on Insane?
But maybe not.
