You need to consume Vigor for each level of Adventure. When your Vigor is not enough, you can choose to lock your Vigor. You can get rewards from defeating Bosses even when your Vigor is locked. Your Vigor is limited and important. So how to save your Vigor?
How to get more Vigor?
Each Adventure level consumes 1 Vigor point. When you have too much Vigor, each level will consume 3 Vigor points, and you will have 300% bonus for EXP, Badges and Coins.
Currently, Vigor will be restored after several hours or gained by Online bonus. At 4 o’clock, 12 o’clock and 20 o’clock, 60 Vigor points will be restored (10 more Vigor points for activated Monthly Card). You will also gain 30 Vigor points in total after completing all Online bonus.
If you have found your Vigor is not enough, you can lock your Vigor to reduce the consumption, especially in the Assist and low-level adventures. You can’t lock Vigor when it reaches 180 or above. After it reaches 240, it will be deducted by 2 times, 3 times for reaching 360 or above, of course, the rewards will be more.
Tips
Lock your Vigor when it is lower than 180. You won’t consume Vigor during levels, but you unlock it at Boss level, then you gain the rewards from defeating the Boss. (Note: If you lock your Vigor, your gains will be 0 in adventures.)
Note: you need to unlock Vigor 2 levels before Boss fight (for example, level 8, 18,28...), otherwise you have no rewards
