: life-enhancing spell will derail it.
Yeah, that was actually the theory I came up with before Myth 2 came out and the Stygs appeared. But I just can't understand what pure "life" and "unlife" would be, so I feel bound to explain it pseudoscientifically. Maybe the root acts on the microorganisms inside the armor and on its surface, causing them to multiply at an incredible rate; maybe it attempts to transmute the metal itself into living cells. Maybe its influence travels through the Knight into its maker and heals him; since he animated the Knight with a piece of his soul (which could count as a sort of injury), when the healing process restores that piece to him the Knight is destroyed.
