Campaign Details

 

 

Campaign Features

You can only use special Temporary Relics! Map "Depths of Space-Time"!

You won't be able to take Relics on the "Depths of Space-Time" map during the "ECHOES OF ADVENTURE" campaign, so put together strategies using the special Temporary Relics!
Try to clear the map by choosing Temporary Relics that work well with your deck!

Enjoy battles that oppose Relic-using decks! Map "Duel Against a Mighty Foe"!

The enemies that appear on the "Duel Against a Mighty Foe" map in the "ECHOES OF ADVENTURE" campaign will use decks that grant the same effects as Relics you can use!
What might happen if you use the Relics allowed during Ranked Matches? Find out through these battles!

Clear the map with the specified Heroes to get rewards!

A new Challenge to clear the map with the specified Heroes in the event "ECHOES OF ADVENTURE"!
You can obtain "Platinum Coins" by completing the Challenge, so be sure to take it on!

Defeat the bosses to get limited Relics!

Relics that can use cards of past bosses will appear in the "ECHOES OF ADVENTURE" campaign!
The Relics listed below only drop from certain bosses, so take on the map lots of times to obtain them!
 

Tough enemies assemble! New maps "Battles Against a Mighty Foe" and "Extreme Trial"!

The ☆☆☆☆☆ map "Battles Against a Mighty Foe" and ☆☆☆☆☆☆ map "Extreme Trial" appear in the "ECHOES OF ADVENTURE" campaign!
In "Battles Against a Mighty Foe," just as in "Duel Against a Mighty Foe," you will be able to enjoy battles with decks granting the effects of existing Relics!
Moreover, bosses that appeared in high-difficulty maps in previous campaigns will assemble in "Extreme Trial"!
By defeating all the bosses, you can get Emblems, so be sure to give it a shot!
Also, if a Treasure Chest of Platinum Coins appears, you are guaranteed to get one of the Relics listed below!
They will be easier to obtain than in other maps, so it's a great chance to go for them!
Also, by clearing it, a Challenge appears in which you can get Platinum Coins!
Don't miss it!

The high-difficulty ☆☆☆☆☆ map "Space-Time Distortion" appears in the "ECHOES OF ADVENTURE" campaign!
Intruding enemies from previous campaigns will come back in "Space-Time Distortion"!
There are Challenges based on the number of wins against intruders, so take on the maps and intruders lots of times!
There will also be Challenges other than battles against intruders, so be sure to check them out!
Also, cubes are more likely to appear as rewards after winning battles in "Space-Time Distortion," so we recommend leveling up your Relics!
■ Intrusion Progression
1. Select a map marked with an Icon.

* Intrusions will only occur on maps marked with an Icon.
2. Fight enemies on Battle Tiles and Tough Enemy Tiles!

* Intrusions will not occur on Boss Tiles.
3. When you win a battle, there's a chance that an Intrusion will occur!
4. Intruders Are Tough Enemies, So Be Prepared!
5. If you're not feeling confident about the outcome, you can return to the map without battling by tapping the button on the top left!

Please note that if you choose not to battle, you will be unable to battle the intruders again until another Intrusion occurs.
