Finishing up the Garuda EX a BLM targeted Garuda and did a 3 bar limit break. Garuda then teleported to him and with a sliver of health left, Garuda, Suparna, and Chiranda would not take damage.
This was enough to make me unsubscribe from the game. I'm not going to work for hours to teach people a fight only for it to be unkillable.
