Pretty straight forward glitch. Omnislash kills spectre's haunt illusions in 1 hit, as if they were neutral creeps, when it is definitely not supposed to.
It says right in the description:
Creeps are killed in one hit of omnislash. (this does not include player controlled units or ancients).
Bizarrely, this only applies to illusions from haunt. I have tested the following illusion skills:
Replicate: Not killed
Disruption: Not killed
Spirit Lance: Not killed
Dopplewalk: Not killed
Juxtapose: Not killed
Mirror Image (Naga): Not killed
Phantasm: Not killed
Wall of Replica: Not killed
Manta Style: Not killed
Illusion Rune: Not killed
Haunt: Killed instantly even at 7000+ HP
This can make the juggernaut vs spectre matchup totally broken. He can kill a full haunt with omnislash with plenty to spare (enough to kill a refresher haunt even), when if it worked like dota 1, haunt would screw omnislash up and not the other way around. Its a very gamebreaking bug for the matches it applies to.
