A video of floor 191-200 of my first ever POTD solo clear \o/ and got The Necromancer title 25:10 - how not to use rage...... almost ended my run by doing a dumbdumb.
It got de-aggroed, you can tell by the fact that for a split second its hp bar got to the different color, wildfire was still on and engaged the mob immediately after that even though the knight still ran to it's initial spot and restored hp to full. It's a bug that rarely happens when u'r running very close to one of those fog walls, the mob u'r fighting gets de-aggroed.
