Surtr & Múspell Strategy

Go for a player phase strategy!

With the lack of refresher units and 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 careful around immovable terrain such as the pillar and the trees near the starting area.

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.

You may bait the enemies on the tree tile in the middle, with allies surrounding the bait unit and providing support. Múspell, the Lance Flier, and the Green Mage can reach that tile and attack, but the entire left side of the map will be unable to do anything.
