Description
A creature or character that is marked for death will be sentenced to death following a multitude of turns (around 2-4 moves after being afflicted).

To get rid of it there is only one way possible in battle: you have to win the fight before the Mark kills you.

Alternatively, fleeing a battle will erase the effect from that character.
