In the Plague of Shadows campaign, during the penultimate boss fight Spoiler:against the titular Plague of Shadows inside Plague Knight's mind, you can defeat it by standing still and doing nothing for around 40 seconds, because the boss cannot hurt you in the spot you stand in at the very start of the fight. After this time has passed, the boss (labelled as "????" in the game's text box) will say:

????:Spoiler:YOU ARE STEADFAST IN YOUR RESOLVE... MAYBE THERE'S HOPE FOR US YET...


before transforming into its second form and the campaign's final boss fight, Spoiler:the Corrupted Essence.
