Currently if a troll spawns as the boss is breaking the second platform, the troll will continue to run to the already destroyed platform and break it a second time spawning a second nereid from the same platform. It is nearly impossible to recover from this as the boss stands in front of the troll while he breaks it at the angle you are required to hit it from on the final platform.
