Stage 3: The First Move
Verringert die ABW von Gegnern in der Nähe um 25 %.
Führt eine Attacke mit Attacke-Wert 80 auf die Gegner in der Nähe aus und verringert ihre ABW um 13 %.
Erhöht die ATT der ausführenden Trabanten um 60.
Actually, the strategy is exactly like before. For lazy people, I'll repeat myself: use Kidragoras, or, if you don't have it, any Mammet. The idea behind the Kidragora is to have Minions strong against Arcana Stones. They also have the highest Attack in this category.
Spend all your points in 4 Kidragoras at the B Gate. Switch to Gate A or C before the timer ends.
Grab all your Kidragoras and send them to the middle Arcana Stone. Let them attack it and ignore them for a while.
Now, summon 4 Kidragoras in A and 4 other in C. Send them right away at the corresponding ennemy's Arcana Stone (left or right). And now, you wait.
Arcana Stones should go down quickly and your Kidragoras should survive any encounter. If the opponent's Minions are in range when your Special Action is ready, feel free to use it.
You can basically ignore attacks on your own Arcana Stones. Just re-summon if one of them die - this shouldn't happen. If you're bored, or want to play it safe, you can summon one tank per Arcana Stone, to protect them. I used the Demon Brick because its cost is low (15), but I guess any tank would do.
