Vengeance: Delving deep into potent magic, some creatures may inflict Vengeance damage. This effect (which may normally only be delivered via Ritual sources) may not be avoided or mitigated in any way, including defenses such as Reduction and Immunities or skills such as Phase or Resolute. If your character takes Vengeance damage, it will be taken no matter what skills or abilities you try to use on it. This will never be delivered as a weapon swing or packet, but instead only by powerful abilities like Warder Glyphs or on reaction to a Killing Blow.
