This is by far the least buggy encounter in the history of the universe. Not a single bug could ever possibly exist, it’s a true testament to Square-Enix amazing QA team. I don’t know how their development team could design the game so poorly.
Imagine this scenario
Cracks starts showing on the ground. Player X runs immediately 20yd away. After being 20yd away crack on the ground explodes. Player X gets hit by the explosion although he is 20yd away. Player X dies.
How is this even remotely fucking possible, it must surely be the most horrible broken encounter or the designers have failed horribly in coding this game.
