Tanya and Osian Strategy

Tanya has her Special up!

Tanya will have her Special up at Turn 1 in the Infernal map.

Be careful when dealing with left side of the map, you can use either a unit with Canto like Reginn or take out the Axe Fighter with a ranged unit and then use an Assist skill or dancer to get them to safety.

Use brave units!

These units can also be used to get to safety with a dancer or Reposition.
