Thrasir: Omnicidal Witch Strategy

Use a Bulky Unit That Has Distant Counter

A bulky unit with Distant Counter on their weapon or on their A slot will be able to take hits and retaliate when attacked by the ranged units on this map.

If they're well built and have investment, they can also be able to defeat Thrasir when she attacks.

Reinforcements Will Come From All Sides

The reinforcements will spawn depending on the type of unit you defeat on the map.

Keep in mind, however, that some of them will spawn on the lower right portion of the map, so be careful about your team's positioning as the space to move around is limited.
