The first time I came across them was when homestead was under attack, in that situation I had to destroy the void crystal in that lava map by sneaking a character around and nuking the crystal then all the void monsters died. The phantom forest however I do not know how to kill those ones even though I can kill death knights. I figured there must be another void crystal around but have not seen one there so I just avoided them. Like you, my T-Weapons have no effect on them.
