If any enemy gains a Card Demon, Norn Dravna's next skill cast is guaranteed to critical hit. (Card Demons can be summoned when the host uses a skill, or obtained by copying Cursed Minions from other heroes. This guaranteed critical hit effect triggers only once per turn.)
After matching 20 runes of the same element as a hero in your team, the board will generate 1 Dreamer Rune. Match the Dreamer Rune to heal all allies for 10% of their health. (When defending, all allies will be healed for 10% each time this hero attacks a total of 5 times).
