Frequency: Every time
Monster name: Ravana
Class/Level: 60
Party or solo: Full party
Area and coordinates: Thok-ast-Thok (Extreme)
Steps:
1. Take 0 damage from certain attacks that should inflict "Physical Vulnerability Up" in the Ravana (Extreme) fight.
2. You won't receive debuff when you should.


There are certain attacks in Ravana Extreme that inflict a debuff when hit, and those attacks play a part in the mechanics of the fight. By taking 0 damage (through means of extreme preparation, and therefore would imply not being the original intention of the dev team), the debuff that plays a role in this mechanic never comes into a play, and therefore players are able to skip the mechanic entirely, nullifying Ravana's ability.
