Mythic Hero Battle: Hræsvelgr Strategy

Use a Player Phase strategy with Galeforce and repeated actions

It is possible to clear this map with an offensive strategy if the team is properly built.

Due to the distance between your starting position and the closest foes, we suggest spending the first turn to position your units in preparation for the second turn. However, keep in mind that Hræsvelgr's Divine Talon grants +1 movement to her allies at the start of her turn.

The enemies will approach your team, but be unable to reach if you positioned properly.

On the second turn, begin clearing the generic foes using offensive units. Ideally, your offensive units have ways to generate additional actions such as Galeforce, Brave Felix's Lone Wolf, or Duo/Harmonized Skills.

As long as you remain outside the threat range of enemies you aren't able to defeat on the current turn, the enemies will not be able to snipe one of your units down. The enemies on this map have no refresher or warping skills to catch you off guard.

Alternatively, use Savior units to tank the enemies

An enemy phase tanking strategy is possible in this map, but requires proper teambuilding to avoid getting crippled by Hræsvelgr's Quieting Claw.

The easiest method is to field Elimine to prevent Quieting Claw from inflicting Spd/Def-7, 【Exposure】, and Null Miracle onto your units. This method also prevents Divine Talon from granting +1 movement to Hræsvelgr's allies.

Alternatively, you can field heroes that cleanse penalties at the start of each turn or phase such as Freyr, Attuned Micaiah, or even your own copy of Hræsvelgr.

At the start of the first turn, position your units so that the bait unit is protected by both a Near Save and a Far Save tank. The enemies will run in and attack, leading to their defeat.

Hræsvelgr' is the only hard-hitting enemy on this map due to her pre-charged Nimble Beast. If your tank units can survive one round of combat from her, simply deal with her the same way you defeated all the other enemies.

However, if your tank unit cannot withstand one round of combat, bring an offensive unit on this map. This unit's role is to defeat Hræsvelgr when she approaches your team. Ensure you keep the offensive unit within range of your Savior Tanks to avoid losing the map.
