Prepare A Fire Affinity Weapon

Fire Affinity Weapons Are Easier To Obtain In Ruins With Fire

The Affinity is displayed at the bottom right of the base icons on the map. Fire Affinity weapons are easier to obtain at bases where the Fire icon is displayed so be sure to clear them by the final day.

The Warhammer "Cranial Vessel Candlestand" Is Highly Recommended

The Unique Skill "Surge of Faith" of the Warhammer "Cranial Vessel Candlestand" can deal massive damage when used close to the boss. If you find it in the field, make it a top priority to secure it.

Equip The Recommended Relics

Since the boss fight will be very difficult, it is recommended to equip Relics geared towards the boss. Prioritize equipping Relics with effects like "Improved Fire Attack Power" to increase damage output, or any stat that prevents the build up of Frostbite.

Increase Sacred Flasks At A Church

To increase the number of Heals, make sure to increase the number of the Sacred Flasks as well. Sacred Flasks can be increased at a Church, and you can check their locations on the map.

Prepare "Warming Stones"

Before you start with the boss combat, it is recommended to purchase various items such as runes and Warming Stones. It is much easier to have so many healing items so that you will not struggle during battle.

Dodge Breath Attacks

Move Away When It Starts Inhaling Air

Fissure in the Fog, after inhaling air, the boss will generate an ice storm.. When it starts to inhale, make sure to move far away from the boss.

Quickly Search For The Boss Once The Sky Of Ice Appeared

If the surroundings are covered in fog, the sky will start to freeze, creating a massive ice layer in the sky that gives a wide range of ice attacks. Only the area around the boss is safe, so make sure to search for the enemies, and move closer to it. If you can't make it on time, make sure you have enough recovery materials for your HP.

Once The Fog Is Up Look For The Ice Pillar

If the surroundings are covered in fog and air starts being sucked into one spot, a full-area breath attack will occur. An ice pillar will be placed on the field, and you can avoid the breath attack by staying behind it. However, if you get too close to the ice pillar, you'll be hit by the breath attack, so stay away from the ice pillar as well while waiting.

Dodge The Ice Attacks From The Air By Rolling

Once it gathers ice in mid-air, it will perform an attack that launches ice chunks. The attack range will be wide, and it will be difficult to evade it even with large movements, so it is recommended to dodge it by rolling to the ground.
