A set inspired by Chinese mythology and specifically the wuxia genre. The Twelve Paths of Heaven are both philosophies of life and styles of martial arts, each named after one of the Twelve Immortals who ascended by walking those paths.

Set mechanics:

Trial

Trial is a variant on level up. Whenever a creature with trial deals damage, it gets a level counter. Note that level counters are applied as a trigger after damage, so death effects won't get the extra level counter if a creature dies in combat.

Enlightened

Enlightened is an ability word that indicates a spell or creature gets a benefit when you have five or more cards in your hand.
