Chapter 22: The Frozen Sea

Chapter 22, "The Frozen Sea," presents a significant challenge due to its treacherous icy terrain and specialized enemy types. Success hinges on understanding and mitigating the environmental hazards, managing status effects, and adapting your unit composition and strategy.

Environmental Hazards: The Icy Terrain

The battlefield is covered in ice, which significantly impacts unit movement and can introduce unpredictable events:

Movement Penalties: Most ice tiles will reduce a unit's movement range. Units that are typically fast may find themselves slowed down considerably.
Slipping: Certain ice tiles have a chance to cause units to slip. This can result in the unit being moved to an adjacent tile (often in a random direction) or, in some cases, losing their action for the turn. Careful positioning is crucial to avoid being pushed into dangerous situations or away from objectives.
Impassable Terrain: Large ice formations or frozen water bodies may act as impassable barriers, forcing you to find specific routes or break through them if possible.

Strategy Tip: Prioritize units with high base movement, such as Pegasus Knights, Wyvern Riders, or units with movement-boosting skills. Consider equipping units with "Pass" if available to ignore terrain and enemy units. Even units with lower movement can be made more effective with skills like "Mountainer" (if applicable) or by using rescue/pair-up mechanics to ferry them across difficult terrain.

Enemy Composition and Threats

The enemies in "The Frozen Sea" are designed to exploit the environment and inflict debilitating status effects:

Ice Mages: These magic users are a primary threat. They wield ice-based magic that can inflict the Freeze status effect.
- Freeze Status Effect: A unit afflicted with Freeze cannot take any action (move, attack, use item, wait) during their next turn. This can leave them vulnerable to enemy attacks. The effect typically lasts for one turn and wears off at the start of the afflicted unit's next turn. There is no specific item or skill to cure Freeze instantly; players must wait for it to expire.
Armored Units: Expect to face heavily armored enemies who resist physical damage.
- Armored Blow Skill: Units with this skill gain a significant defensive bonus (e.g., +10 Defense) when they initiate combat. This makes them even harder to damage when they are the ones attacking. To counter them, consider using magic attacks, brave weapons, or units with high-piercing skills.
Units with Icebreaker: Some enemies may possess the Icebreaker skill.
- Icebreaker Skill: This skill grants the unit bonus damage against any unit currently afflicted with the Freeze status effect. This makes them particularly dangerous if they target a frozen ally.
High Resistance Foes: Be prepared for enemies with high resistance to magic, making them difficult targets for your mages.

Chapter Objective and Boss Battle

The primary objective of "The Frozen Sea" typically involves reaching a designated escape point on the map or defeating a powerful boss. This boss is often a formidable ice-themed creature or a skilled general leading the frozen forces.

Boss Strategy: Before engaging the boss, carefully examine their stats and skills. If they have high Defense, prioritize magic damage or skills that ignore defense. If they have low Resistance, your mages will be highly effective. If the boss has abilities that synergize with the frozen terrain or status effects, be extra cautious.

General Strategies for "The Frozen Sea"

Unit Placement: Careful positioning is paramount. Avoid clustering units on slippery tiles where they can be easily pushed into danger. Keep your vulnerable units away from edges and potential ambush points.
Weapon Triangle and Terrain: While the weapon triangle (Sword > Axe > Lance > Sword) is always important, the terrain can sometimes disrupt its effectiveness. For example, if an axe-wielding enemy is positioned behind impassable ice formations, your sword-wielding unit might not be able to reach them, negating the weapon advantage. Conversely, some terrain might offer defensive bonuses or negate certain weapon types.
Enemy Reinforcements: Be vigilant for enemy reinforcements that can appear from unexpected locations, often emerging from the icy mists or off-map. Ensure your flanks and rear are adequately defended or have units capable of quickly responding to new threats.
Skill Synergy: Units with passive healing skills like Renewal can be invaluable for sustained combat on the hazardous battlefield. Skills that provide mobility or allow units to bypass terrain can also be game-changers.
Map Features: Pay attention to any interactive map elements, such as destructible ice walls or frozen rivers that can be opened or closed. These can alter pathways, create strategic advantages, or block enemy advances.

Mastering the interplay between your units' abilities, the weapon triangle, and the unique environmental challenges of "The Frozen Sea" is the key to achieving victory in this demanding chapter.
