Small corruption monster always hitting/ignoring player evasion.

I came across what could be a bug or maybe a monster with a few too many zeros behind their accuracy stat.

A small monster that spawns when you kill enough monsters close together in a corrupted map, it attacks using a yellow arc lighting type of attack.
My character relies mostly on evasion at this point until I can get my energy shield online so this problem was especially noticeable to me.

Despite my evasion chance being around 81% it seemed that this one monster didn't ever miss against me despite my high evasion and the fact that there were no accuracy modifiers on either the map nor the monster itself. No other monster on the map was hitting me abnormally often and even the white mob variants of this particular monster seemed to hit with every attack. If there was more than one of these that spawned in a pack then my character was almost guaranteed to die as their combined attacks would overwhelm me before I could take them down amongst the rest of the monsters. In the end I was unable to finish the map due to running out of portals.

I hope my brief description of the monster is enough as I didn't think to take a screenshot of it at the time. I can only describe it best as a very small corruption monster that shoots out a yellow colored arc lightning type attack.

Edit: I managed to encounter this monster again and this time I took screenshots.
