Other Performance and Upgrades

Synergy Combinations At the end of each wave, you'll choose a random upgrade card. You need to consider synergies such as the skills of the rabbit you're primarily developing, special effects of carrot ammo, and area-of-effect debuffs to complete your own deck combination. The recent update has improved the early stage setup and the number of draft card selections, making it easier to manage than before. Internal Development and Constant Growth (Village Content) Smart Farm and Relic Upgrades If you get stuck on a stage, return to the village to level up your Smart Farm or challenge dungeons in the Ancient Relic Laboratory to collect advanced relics. Rabbit Synthesis Use your collected fragments to synthesize rabbits in bulk and increase their star grade to boost their base stats, which is essential for breaking through later stages. Charm Equipping Once you reach stage 10, play the unlocked Co-op Defense and appraise the charms obtained from reward chests to equip them on your rabbits for additional stat boosts.
