A ghost holy freeze aura in the Hall of Pain in hell difficulty

A unique monster equipped with

Holy Freeze aura popped up in the Hall of Pain in hell difficulty against my trapsin. She cleared the area without any issue, however, the

Holy Freeze aura stayed at the spot where the respective owner unique monster was put down, and it kept shooting at the trapsin and/or the merc/

Shadow Master when either was close enough. Is that a new game feature, or just another hiccup bug?

not a bug, it's a FEATURE XD
like game crashing a lot and getting disconnected from the server.

Lmao - well, I have never seen that one before. The aura became self aware.

That's a first, loved it.

Ghost tried to play pranks but forgot the aura active
