Before you start your turn, Goldmary will notice about the changing of the tide. When water flows in, some tiles will be stuck with some water and this will make you reduce your Avoidance. You can still make your move through it, just be careful not to end your turn on it. if you have flier team units with you, they will no be affected by it.
There will be a corrupted Wyrm nearby that you must defeat.
If you select Rosado, a turorial about Emblem Eirika’s abilities will be shown up. Emblem Eirika switches with her twin brother, Ephraim, to adapt to different situations.

The engage skill Sacred Twins enables the unit to invoke Eirika and Ephraim’s skills simultanuosly. The engage attack Twin Strike hits with both sword and lance, making it easier to break foes, and deals bonus damage against the corrupted.
These abilities will help you strike through the Wyrm’s defenses. The corrupted Wyrm has attacks that will hit you up to four tiles away so your only option is to get close to it.
The water move back in every two turn cycles, when the water subside, it is your turn to move around the map, Flying team units will not be affected by it. Always check enemy weapons to make sure you are charging the right enemy, also always look after the danger radius and check enemies class you plan to charge to make sure you will not be fighting the enemies that have advantage in you.

Mauvier also has a Revive Stone so this means you have to defeat him twice, If you have a team unit that loaded with anti-cavalry weapon like Axe, attack him with it to apply Break, Mauvier attack is fatal so make sure you inflict a Break attack so he cannot make a counter-attack. some magic weapon will also be useful to attack him. After defeating Mauvier, you will obtain a Spirit Dust item and the battle ends here.
