Co-op Mode - Rewards

Rewards:
Challenge Co-op Stages with another player and earn more rewards based on how many rounds you persevere.
Complete all rounds to also earn rich Clear Rewards. The 1st clear reward resets weekly.
You can invite other players via the chat, as many are willing to take on powerful foes with you!
If you cannot find a co-op partner for the moment, you can use the AI Co-op feature (though, Co-op assisting will not be available).

Attempts:
If you've used up all Attempts, you can use Assists to join other players' games for some rewards. Keep an eye on the chat to see if anyone needs help!
If you've used all your attempts and assists, you can still help others but doing so won't grant rewards.
Both of these reset daily.

Blitz:
You can spend Blitz Tickets to quickly complete a Co-op match to earn Round Rewards.
Blitzing will grant you rewards equal to your highest round reached that day. So keep that in mind!
Blitzing also uses up Attempts. Assists cannot be used to Blitz.
