Mythic Hero Battle: Fomortiis & Gotoh Strategy

Use Player Phase Units!

If your barracks has units with multiple actions, it is possible to mount an offensive on turn one and clear the top half of the map.

On your turn one, before the enemies act, Fomortiis is still untransformed and thus does not have access to his Special cooldown accceleration and Distant Counter effects. Armed with this knowledge, you can target his allies with a ranged unit, which will force Fomortiis to trigger his Savior but be unable to retaliate. If you have powerful enough units, or attack multiple times, you can defeat him on turn one!

Using these units with multiple actions, clear the top half of the map, since both the Axe Knight and Gotoh are unable to reach your units on the first turn.

Use the following turns to implement a Hit and Run strategy, defeating foes in range and then retreating to safety.

Use a Savior strategy!

A 【Savior】 strategy is also possible on this map with properly built Save tanks and support units.

Using this strategy, Fomortiis is rendered immobile and can be safely ignored until the end.

Position your team ball in the middle of the map, taking caution when Gotoh approaches.

If you have a unit that can pierce non-Special damage reduction through skills like Lethality, Deadeye, or exclusive skills like Legendary Veronica's Enclosure, field them and use them to defeat Gotoh.

Alternatively, equip a unit with the Hardy Bearing 3 Sacred Seal to dodge Gotoh's massive damage reduction on consecutive hits. Hardy Bearing also provides additional utility against the Blue Flier with Spd Preempt 3!

Take note of notable generic enemies

The following generic enemies on this map have notable skills that need to be kept in mind:

• The Blue Flier on turn one has Spd Preempt 3 and Phantom Spd 3, allowing for an instant retaliation against ranged foes.
• The Lance Dragon on turn two has Odd Tempest 3, which can surprise you on turn three. Keep the extended threat range in mind.
• Both the Sword Knight and the Lance Knight on turn three have Assault Troop 3, which allows them to move up to three spaces in cardinal directions.
