temporal displacement is triggered exactly like vampire, just instead of healing it produces a damage absorption barrier.
if traveler does 2 damage to your opponent, it will add 2 damage absorption to its owner. next turn, if an abyss crawler attacks you, two damage will be absorbed, 4 damage will go through. if the next creature is another abyss crawler, all six points of damage will be done as the 2 damage absorption was already used up.
