Completing the trial will grant access to a ritual that will improve your mark giving it a soft counter effect against a specific card.
Every time your opponent plays that specific card your mark will generate 5 extra quanta and heal you for 5 hp. (6/6 if you completed the trial in hard mode).
Reading the op helps, Atico.
Ohh, now I understand
My language isn't so good, so when I saw this topic I thought about idea which I wrote. Sorry
On the other hand, maybe it will be more interesting, when bonus for mark will be other than 5 quantum+5 heal. Maybe all Marks should give 5 quantum and Time mark should allow draw second card, Life Heal by 5, Light Heal creatures, Air increase airborne creatures attack etc.
