Echidna and Larum Strategy

Use a Hit and Run strategy!

This map has no reinforcements, making a Hit and Run strategy viable. It also helps that most of the enemies are grouped together, allowing Galeforce users to immediately go on the offensive after their first actions.

Larum is a refresher unit with her Dance assist skill. Predicting the enemy AI can be difficult if you are not aware of the AI priority order of operations, thus, it is advised to defeat Larum quickly and then retreat to safety once she is removed from the map. Defeating her using a ranged unit, and then using your own refresher kills and movement assists like Reposition

Outside of Echidna and Larum, the enemies in this map are not too threatening. Echidna has two sustain skills in Atk/Spd Finish 4 and Atk/Def Bulwark 3, which will keep her HP up especially with the Cleric's own healing capabilities. Luckily, Echidna is in the front line, allowing you to pick her off with an offensive unit and then retreating to safety afterwards.

Alternatively, use a tanking strategy!

The enemies here can be defeated with a tanking strategy easily, as none of them are too threatening, especially if Echidna is kept away from her allies to deactivate her Atk/Spd Finish 4. Most modern day tanks will survive hits from all the enemies on this map if provided appropriate support.

Choose a side to bait the enemy units on, and place your tank unit in range of the enemy units. Place the support allies near the tank unit but out of range of the enemies, and allow the enemies to approach.
