Affinity Auto-Battles is a special event introduced in Version 8.0.0. It was first presented in Feh Channel (Dec. 4, 2023).

Affinity Auto-Battles is an event in which Heroes are dispatched to different worlds to take on missions with the help of other Summoners' Heroes. The affinity between the two teams is determined before battles, which also strengthen them. Because battles take place using Auto-Battle, the better the affinity results, the greater the advantage in battle.

Basics[ | ]

Affinity Auto-Battles has a very simple gameplay: the player creates a team with any heroes and select one among three proposed other player to fight alongside. There are no restriction on the number, type or duplicativeness of the heroes. The team of the other summoners will be the one they used during this event, or their Arena Defense team by default. Friends are also more likely to appear among the three suggested players. Note that it is possible to refresh the three presented players to have a new selection.

Once a partner has been selected, an affinity test is performed between the two players' teams, resulting in a score between 0 and 100. When the affinity level is between 25 and 50, every hero is granted +2 Atk/Spd/Def/Res, and +4 when the level is greater than 50. The affinity is random, and may change between tests given the exact same players and heroes. However, it is possible to raise the score when all the heroes from one player, or the two players, are from the bonus games. It can be further increases when one player has all heroes from one of the bonus game, and the other players from the other game, or when both teams are comprised of half heroes from one game and half from the another.

After the affinity has been calculated, the player must choose one of three stages to battle, with varying enemy levels. All three stages costs 15 staminas to play, and are comprised of 6 foes. The battle is performed automatically through Auto-Battle. After 10 turns, or once one side is vanquished, a score is granted as follow:

BaseScore x DefeatedFoes + BaseScore x SurvivingAllies + AffinityLevel

The BaseScore depends on the stage: 50 for Normal, 55 for Hard, 60 for Lunatic. Once per day, the score is also tripled. Rewards are granted based on the cumulative score.

Story[ | ]

Anna Commander Face Cool

Now that everyone's here, let's get
started. We're about to work with the
Orders of Heroes from other worlds.

We'll be referring to this joint mission
as Operation Affinity!



So we get to test our affinity with
one another? I love that! I'm going
to get my affinity tested with every—

Sharena, remember that we have
a mission to carry out.

Orders from other worlds will also
be dispatching teams, just like us...

Their teams and ours will be pairing
off in groups of two teams, each from
its own separate world.

Whether the units are compatible
is of utmost importance.




What makes one pair of teams more
compatible than any other?


Alfonse Prince of Askr Face FC

...It's unclear.

Affinity isn't an exact science.

But there certainly are worlds out
there that our Heroes have high
affinity with...

We just have to hope luck pairs us
with them more often than not!

Got it! Then we should expect that
we won't be a perfect match with
everyone out there...

Now, just select our Heroes and
begin by dispatching them into
the field, 【Summoner】!
