The next update will be an epic one, which will significantly adjust many aspects of the game. For example, the bond for [Spirits] has been modified to: After each attack, randomly gain or apply 1/3/8/24 gold, luck, vitality, poison, or weakness; [Vampires] will regain an additional 3/8/20/60 health whenever they deal damage; for every 10 damage dealt, permanently increase damage multiplier by +0.01/0.02/0.03/0.05 (provisional, not final version), and so on. Currently, we are intensely balancing and debugging, so please stay tuned and look forward to the new version coming soon!
