The Vault of the Four-Fold Discordance
A sophisticated warding chamber where the four elemental planes collide. The room is a perfect cube, forty feet on each side, with a central levitating monolith of crystalline quartz that hums with dissonant frequencies.

Defenses
Detection
“The walls are divided into four quadrants: charred basalt, frosted silver, polished brass, and porous limestone. In the center, a large octahedron of crystal rotates slowly, sparking with erratic energy while four bronze rings orbit it at high speed.”
Standard Engagement
A creature enters the room without speaking the command word or presenting a Shaper's Key.
The hazard takes 3 actions. On each of its turns, it first rolls 1d4 to determine the 'Predominant Element' for that round: 1. Fire (Inferno), 2. Water (Flood), 3. Air (Storm), 4. Earth (Quake). It then uses its remaining actions to pulse with energy. Action 1: Planar Pulse. The room fills with the predominant element, dealing 4d10+15 damage to all creatures in the room (DC 33 basic Reflex save). The damage type matches the element: Fire (fire), Water (cold), Air (electricity), Earth (bludgeoning). Action 2: Secondary Manifestation. Based on the element, a secondary effect occurs: Inferno (all creatures are Dazzled for 1 round), Flood (the floor becomes difficult terrain for 1 round), Storm (the hazard makes a +26 ranged attack with a lightning bolt against one target for 3d12 electricity damage), Quake (creatures who failed their save are knocked Prone). Action 3: Intensify Resonance. The hazard increases the damage of its Planar Pulse by 2d10 for the next round (this effect stacks until the hazard is disabled or reset).
The hazard resets automatically after 1 hour of inactivity.
If the hazard's damage bonus from 'Intensify Resonance' reaches 6d10, the crystal explodes. This deals 15d10 force damage to everything in the room (DC 36 basic Reflex save) and destroys the hazard.
A character with an elemental bloodline or trait matching the Predominant Element for the round gains a +2 circumstance bonus to their saving throw against the Planar Pulse.
