Character Name: Martel
Race: Elvaan
World: Ragnarok
Main Job: Paladin
Support Job: Blue Mage
Area and Coordinates: Dynamis - Bastok [D],
Party or Solo: Alliance, 18 members
NPC Name: N/A
Monster Name: Volte Shinobi
Steps:
1. Fight Volte Shinobi.
2. Volte Shinobi performs a Skillchain on the player.
3. Volte Shinobi uses Mijin Gakure, while the magic burst window on the player is still open.
4. Player takes extremely excessive damage. (99,999)
For reference the regular damage from this attack is 4,000.
This is speculation, but considering that this only seems to happen if the Volte Shinobi uses Mijiin Gakure on a player with an active magic burst window I can only assume that the ability is somehow magic bursting, despite being non-elemental. A similar issue occurred during the last Gigas ambuscade with the Mercurial Strike ability.
I believe that this is not intended behavior because upon release of each dynamis zone, this never happened. It only started happening much later. I don't have exact times when this issue first occurred.
