Behemoth's rocks in the Crystal Tower series. Those who don't do the mechanic die. In Syrcus Tower that follows it, you hide behind the crystal to avoid Curtain Call or die as everyone stares at you being the only one to greed the boss. In a required Endwalker dungeon, there is a similar mechanic where you hide behind a crystal to avoid death. In the required Endwalker dungeon right before it, you have to hide behind something twice or you either die or get significant vulnerabilities and bleeds.
