Fae and Idunn Strategy

Watch out for Idunn's Special!

Idunn's Special is active at the start of the map in the Infernal version, which means that your units will take a lot of damage when she attacks.

Don't engage her with a melee unit, as she grants herself additional stats and gives herself a guaranteed follow-up attack because of Vengeful Fighter 3.

Defeat Idunn with ranged tome units, as her Res is lower than her Def.

Fae can counterattack regardless of range

Fae has Lightning Breath+, which allows her to counterattack regardless of range.

As her Res is higher than her Def, try to defeat her with a physical damage unit, preferably units that have dragon-effective weapons like Falchion.

Field units that are effective against dragons

There are several dragons on this map, so using units with dragon-effective weapons or Specials will help in clearing faster.

The Blue Fáfnir has Guidance 3

Be careful when baiting units, as the Blue Fáfnir has Guidance 3, which will allow infantry and armored allies within 2 spaces to move to an adjacent space to them.

Idunn and the Red Bow happen to be armored and infantry respectively and will be able to move close to your units at the start of the enemy phase.

Take out the Blue Fáfnir as soon as possible with a unit that has a dragon-effective weapon!
