Mod of Redemption/Irradiated Behemoth

The Irradiated Behemoth is the third mini boss fought in the and the last one faced in Hardmode before the Moon Lord is defeated.

While the Irradiated Behemoth is alive, the music will play.

Spawn
The Irradiated Behemoth does not spawn on its own and is summoned by right-clicking the monitor in the Abandoned Lab's Beta Sector, which is unlocked after defeating the.

Behavior
It behaves like a vertical Wall of Flesh, moving downwards slowly. While descending, it will alternate between firing several 3-shot spreads of tile-piercing gas projectiles or a barrage of fast green slime projectiles.

Being above the Behemoth causes it to fire gas clouds upwards that incur massive damage, meaning that it effectively instantly kills the player if it crushes them.

Similarly to Wall of Flesh, Irradiated Behemoth's body doesn't take damage, however, Irradiated Behemoth only has one segment that can take damage, as opposed to Wall of Flesh's 3 segments.
