The main engine behind the mod's four escalating states.
World Corruption Progression is the main engine behind the mod: the world moves through four states, Level 0 through Level 3, each unlocking new entities, events and visual distortion.
Advancing from Level 1 to 2 requires throwing a defeated Skinwalker into the void; advancing from 2 to 3 requires the same with The Broken One. Reaching Level 3 starts the seven-day endgame countdown, and defeating the Integrion Bossfight resets everything back to Level 0.
