+TO-DO:
+Slighly(400ms) after spell cast 33965 creatures 19198 are spawned. I guess he forces all enemies including pets(9 summoned units
+and 9 units in his threatlist) to cast 39186(19198 were created by that spell(sniff)). Summoned by that spell creature 19198 casts 33496
+on self after being summoned. Then probably they casts 33497(Pull Towards: (150)) on their creators and that's how that knockback is handled.
+If you look closely, players are knocked to random destinations with random angles, means there is no only one spell which handles knockback.
+19198 despawns after 800ms after being summoned.
