Last game, during an encounter, a player which created a mark took a few to many hits and went below 0 hit-points. The bard used an immediate reaction to bring him back to the action, but for a split second the creator was unconscious, so the mark ended.
A mark ends immediately when its creator dies or falls unconscious.
The players however disagreed with this and i was not 100% sure myself.
Was my interpretation of the rules correct? And if yes is there a way to keep the mark active even though a dive through 0 HP?
