[Module] KMS - The Boss Thread

Did you use those skill names from Maple Archive? I recognize them.
Unknown skill 171 - The bomb that Cygnus places on you
Unknown skill 173 - When you get trapped in a Tornado
Unknown skill 178 (not in this thread, used by a few Pyramid PQ mobs) - slows your attack speed by 2 stages
Unknown skill 181 - Pulls you toward the target (used by Hilla's altar as well)
Also, for Von Bon in the other thread, it says Unknown Skill 190, but MA says 191.

Unknown skill 173 when cygnus summon tornado and twister that lock the player in the air for about few sec is call AirLock
