Dark Mana

Dark Mana is mana that has been corrupted by aberrations. If the pure form of Dark Mana touches individuals, it causes burns initially like fire or acid then it slowly corrupts the bodies internal mana and starts turning them into corrupted versions of themselves. The diluted version of Dark Mana can corrupt somebody's internal mana but doesn't burn like the pure form. The diluted version of it after being left for too long, transforms the landscape around it into a Dungeon.
