Tethys & Ewan Strategy

Go for a player phase strategy!

With the lack of reinforcements on the enemy team, a player phase strategy involving a unit with Canto, a unit with multiple actions, or a refresher unit of your own works wonders on this map.

You may opt for a quick clear or a Hit and Run strategy to whitte down the enemies one at a time.

The enemies here aren't bulky and should die in one round from modern offensive units. Just be aware of AI patterns and avoid getting caught by a unit getting Danced by Tethys.

An enemy phase strategy is also possible

Opting for an enemy phase strategy such as tanking is possible in this map due to the lack of heavy offense on the enemy team.

Using tried and tested tank units like Brave Hector and Ascended Fjorm, given appropriate support, tanking all the enemies on this map is not difficult at all.
