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!

Units with brave weapons like Reinhardt or Lex are useful in quickly clearing this map.

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