Duelyst received a new patch this week, 1.82, and with it came a spanking new expansion, Ancient Bonds, 39 cards, and a new keyword, bond.
Bond triggers an effect whenever minions of the same tribe are played on the board. One such card, the Ragebinder, restores 3 health to the General whenever a bonded minion is played.
Much like the previous expansion, Rise of the Bloodborn, card from Ancient Bonds can be acquired through a new orb in the store, but you cannot receive any duplicates. Meaning once you’ve purchased 13 orbs, you’ll have received every card in the set. The only randomness is the order in which you’ll receive them.
You can read more about the patch right over here.
