Chaos God

Chaos God is the second boss that can be found in the Temple, and is a massive, greyscale humanoid with what appears to be a visible ribcage, horns, and a black void where a face would go. Chaos God can be summoned by defeating Warden at tier 4, and is fought directly after Warden's death, and is summoned as part the same cutscene that ends Warden's fight. Chaos God's fight is one of the only fights in the game that open up the space in the HUD for more space to fight. Chaos God is fought in an area that resembles space, with a disc of some sort of matter spinning at the bottom of the screen with stars flying across the screen above.

Attack Patterns
Many of Chaos God's attacks are shared between phases, and instead of new attacks replacing them, they increase in difficulty as the fight progresses. There are also portions of the fight where Chaos God retreats to the background, and uses special attacks while they are invulnerable for the duration of the attack. No attacks occur twice in a row. In hard mode, most attacks are automatically double damage.

Cutscenes
Chaos God is summoned directly after Warden's death in a tier 4 fight with him, and in the same cutscene that results in Warden's death. After rays of light are shown shooting upward from the stonework in the background of Warden's battle, the player ship travels upward and past many chains that break with the player passing them. After traveling up far enough, a disc of matter is shown in an open space with stars, and Chaos God rises from this disc in the background, then teleporting to the foreground and beginning the fight.

If you dodge all the black holes in the final attack of the fight when Chaos God is chained at the bottom of the screen, Chaos God is dragged below the screen as well as the background of the arena. The HUD returns to normal, and you are given a choice between the TempleGame Cartridge and one of the two weapons that Chaos God can provide as loot (Edge of Reality, and Grasp of Entropy). In hard mode, you get to keep both the weapon and the cartridge, but the weapon is still randomly chosen. You are then free to exit the Temple and into Sanctum.
