Normal Combo Cards can be obtained from difficult Shadow Missions, Theater Missions, and Hard Mode Dungeons. These Combo Cards provide a variety of ways to dispatch your enemies. If you perform a skill set in a specified order, each consecutive skill will gain a damage bonus. Unfortunately, even if you find a good card where all skills synergize, it will expire within 30 days.
Premium Combo Cards are the answer to your Combo Card Woes. By picking up a Premium Combo Card Summons from the Web Shop, you will be able to generate a Premium Combo Card, right there on the spot. This combo card is similar to normal combo cards - it has between two and six slots, each containing a different skill. Premium Combo Cards will also expire in 30 days from the moment they're created. The difference between a Premium Combo Card and a normal Combo Card is that you can change skills and even extend the lifetime of your Premium Combo Card through other items!
Suppose you generate a 4-slot Premium Combo Card, but one of the skills just doesn't synergize with the rest of the skills loaded on the card. You can remove a skill and replace it with another random skill by using a Combo Card Slot Change Coupon. Using the coupon will open up a list of your Premium Combo Cards that can have skills changed. Select the Combo Card and the Skill you would like to change. With a little bit of luck, you get a better skill instead!
Now that you've engineering your perfect 6-slot Premium Combo Card, there's no need to lose it to the expiration countdown! You can extend the Premium Combo Card's life by using a Combo Card Extension Coupon. This coupon will extend the life of a Premium Combo Card by 30 days. As long as you keep the Premium Combo Card's life extended, you'll have it around for as long as you need it!
