The Goddess Stones you acquire will be used in the constellation system; which will give you flat and % stats to all characters in your account.
Each level has a fixed cost of stones and gold, which ramps up pretty fast.
At the moment, you can only obtain this currency via the Reincarnation of Stars and the crafting system. Please don’t craft them. It’s super expensive and only for whales.
In no particular order, some tips that helped me auto all bosses to 100,000,000 for the second set of rewards:
This game mode is one of the current endgames we have. If you are a new player, you will not be fully clearing let alone getting 100,000,000 points.
Some bosses have physical or magic damage reduction up to 90%, so it’s better to make two teams and just switch what side they are fighting depending on the enemy.
One of your teams will do most of the legwork since new players don’t have two fully invested teams, make sure your strongest pets are always on that team to guarantee a higher score overall.
We get three free buffs you can check on the Reincarnation of Stars screen, make sure to take advantage of them.
You can retry the bosses as many times as you want, so don’t worry about getting a bad score and experiment with different team compositions.
Lastly, damage is important in this mode. You don’t really need to run a dedicated tank unless they are buffers (like Galahad) or a pure healer like Guinevere, since she does nothing for the team here.
Hybrid type characters are the best sustain here; Ria, Erin, Galahad, etc.
