Coffin of the Iron Mountain

Coffin of the Iron Mountain is a Domain Expansion used by Jogo, derived from his innate technique.

Description
The environment constructed by Jogo's Domain is a fully closed-off stone chamber that resembles the inside (or caldera) of an active volcano. Spouts of magma eject from fissures in the ground and walls, and the Domain's ambient heat is such that ordinary sorcerers will burn up immediately upon entry.

As with any Domain Expansion, Iron Coffin Mountain allows all of Jogo's cursed techniques to hit their mark with guaranteed success, as well as with greater explosivity. An example of such a certain-hit attack is the creation of a large, burning rock that instantly appears at the enemy's location.

Jogo's first and only-seen deployment of his Domain came amid his first fight against Satoru Gojo, in Jogo's attempt to bypass his foe's infinity using his Domain's cannot-miss attacks. However, dangerous as this Domain is, it was easily outpushed and suppressed by Satoru Gojo's Unlimited Void, showing that Jogo's Domain was far less polished.
