The feud

While a marked enemy fights you, it adapts to the attacks you use against it: by weapon class, element and silver, plus your staggers, dodges and back hits. When reborn, it adapts to what hurt it most, up to its rank's worth (at most 3):

• Mailed, Braced, Hewn-hard, Unflinching or Arrow-wise against a weapon class (for example, blades ×0.7)
• Fireproof and the like: +25 resistance, never immunity
• habits: Steadfast, Patient, Watchful, Relentless (+25 Speed) or Night-stalker

All revenant traits are listed on Enemy traits.
