Sain and Kent Strategy

Use a Hit and Run Strategy!

This map has no reinforcements, making a Hit and Run strategy viable.

Focus on defeating the enemies at the top area of the map, specifically the Axe Fighter first if possible. This will prevent Sain from using his Rally Up Atk+, which triggers the effects of the Jolly Jade Lance, granting him an additional action afterward. With the extra action, he can advance closer and add more pressure to your team, so this is one way to prevent that from happening.

After that, with most enemies advancing closer to your team by the next turn, you can start picking them off one by one. The most threatening units left by then should be Sain and Kent, so try to defeat them first if possible.

As mentioned, Sain can take another action after using a Rally skill, so focus on him if you don't want him to move around. Kent will also have premium skills with him and a refined weapon in this mode, making him much more threatening than usual. Try to defeat him quickly as well to lessen the map's difficulty.

Alternatively, Use a Tanking Strategy!

You can also adopt a tanking strategy to clear this map, as most enemies are not too threatening offensively. Sain and Kent are the only units to be mindful of, as they both have the most powerful kits compared to the others.

You can start by luring the units at the top, as they are the closest to your starting points. These units aren't too powerful and can be defeated easily with any of your offensive tanks. However, note that Sain can also reach you despite being at the bottom of the map, as he can gain an extra action from his Jolly Jade Lance.

In the next set of turns, Kent (and the Green Mage if playing in Infernal) will move closer to your team. Prioritize eliminating Kent next, as he can inflict massive damage with his maxed-out kit, which now includes skills such as Atk/Spd Unity, Spd/Def Snag 4, and Alarm Atk/Spd. Use a Def tank, preferably a blue unit to gain color advantage, and lure him into attacking this unit to defeat him.
