Castor Strategy

Use Player Phase Strategies

This map has no refresher enemies, no enemies with movement assists, and there is an enemy in range immediately, making it the ideal situation for a Hit and Run composition.

On the first turn, defeat the Axe Fighter with a ranged unit, and then use post-combat movement, refresher assists, and/or movement assists like Reposition to get the initiator unit out of the danger area.

The enemies will then advance, but be unable to reach your units. You can then pick them off slowly while remaining out of range.

Tank Strategies are also viable

Tank strategies are also viable on this map as there are no enemy units that are too threatening. Even the boss unit, Castor, isn't too difficult to tank, as long as Deadeye isn't charged up.

The enemies will not move until you step into their threat range, giving you time to set up your formation. When you're ready, place your tank unit into the danger area and end turn. Ensure that you can either defeat Castor before he triggers Deadeye, or your tank unit has a Guard effect that prevents Castor from charging up his Special cooldown.

Keep the following skills in mind when setting up your formation:

• Castor's Sudden Panic 3 - ensure your units are not adjacent to each other.
• The Cleric's Def/Res Ploy 3 - ensure your tank unit wins the Res check by having at least 53 Res.
• The Cleric's Incurable+ staff - end your tank unit's turn to remove the debuffs, and then heal them.

As more penalties are applied to your units, Castor's Vulture Bow+ deals more damage. If your tank unit can neutralize their own penalties, then Vulture Bow+ loses a lot of its power!
