2. Normal State |
| Normal State | |
|---|---|
| Dragon Mantle State |
Arkveld has 2 states which are its Normal and Dragon Mantle state.
| Turn Count | Move |
|---|---|
| Turn 1 | Technical Attack |
| Turn 2 | Blade Crawl |
| Turn 3 After Dragon Mantle State |
Technical Attack Prompt for Ratha to increase Ratha's Attack Power |
| Turn 4 After Dragon Mantle State |
Kaiser Blade |
When Arkveld is in the Normal State it will dish out Technical Attacks when engaging in head to heads. Aside from this it will use very powerful attacks like Blade Crawl (AoE) and Kaiser Blade (Single Target).
Watch out for the Third Turn in the Normal State as this will prompt the Protagonist to charge up Ratha for a powerful attack.
Boost Ratha's Attack to charge it up fully to successfully interrupt Arkveld. This can be done through items or stacking Monstie or skills like Power Paean which can be applied as a Decoration to weapons.
| Turn Count | Move |
|---|---|
| Turn 0 From the Normal State |
Elemental Release Used when switching to Dragon Mantle State |
| Turn 1 From the Normal State |
Crushing Chain (Power Attack) |
| Turn 2 | Berserk Blade |
| Turn 3 From the Normal State after Charging Up |
Will unleash Elemental Release if Savage Fireball is not charged up. If Ratha successfully charges up and attacks, it will skip its turn. |
| Turn 4 From the Normal State |
Crushing Chain (Power Attack) |
| Turn 5 | Chain Crawl |
| Turn 6 | Crushing Chain (Power Attack) |
| Turn 7 | Berserk Blade |
| Turn 8 | Crushing Chain (Power Attack) |
In its Dragon Mantle State, Arkveld will release Power Attacks and very powerful AoE attacks like Berserk Blade and Chain Crawl. It will also unleash a poweful attack if Ratha does not successfully interrupt it.
Arkveld, during this state, will also acquire weaknesses for all elemental types it had resistances to in the Normal State.
Ratha
|
Deviljho
|
Dreadqueen Rathian
|
Arkveld will be very weak against Dragon skills during both of its states so having Deviljho would be a good option to take advantage of this. Keep in mind that Deviljho is also very weak to Dragon attacks so switch them out occasionally.
It is highly recommended to build your Ratha before this fight as you will need to boost their attack and unleash a Savage Fireball during a crucial moment in the battle. On the other hand, Dreadqueen Rathian is also a good pick as it can apply Noxious Poison and cover the Speed type attacks during head to heads.

Arkveld will be at level 58 when you fight it and will unleash powerful attacks that can oneshot you. Level up your party to at least Level 50 to prepare your roster.
The Magia Charm is very useful in this battle as it can help restore hearts with Magnificent Trio when set up correctly. Players can also equip the Decoration for Power Paean on it to boost Ratha's attack when charging up.
Additionally, Arkveld will be very weak to the Dragon Element during both of its states so equipping Dragon elemental weapons like the Fiore Nulo Black can unleash higher damage consistently.

Kora makes for a good ally during the fight as she and her partner Monstie deal good damage. She is also able to draw away single target attacks from other allies.
We also recommend finishing her fourth side story as this invites her strong Monstie companion, Golma, to your party.
List of All Characters and Companions
A key mechanic to this fight against Arkveld is to charge up Ratha's Attack Stat before or when prompted in the third turn of the Normal State. Use Attack Boosting Items or Weapon Skills to fulfill this.
Otherwise, the Arkveld will deal very high damage to all members of your party.
Arkveld will have multiple Elemental resistances during the Normal State but will become weak to them during the Dragon Mantle State. Focus on unleashing damage during this state instead of using up stamina early on.
All Monster Weaknesses and Attack Types

The Kinship Skill is extremely helpful when wanting to skip Arkveld's turn so save it until it uses strong AoE attacks like Chain Crawl or Berserk Blade.
Additionally, anticipate when your Partner will use a kinship skill themselves by checking their action above the health bar to save the use of your own Kinship Skill for another turn.
A powerful skill that can help fill the Kinship Gauge faster is Solar Cry. Equip it onto your Monsties so that you can use the Kinship skill more consistently to interrupt attacks.

Arkveld is encountered during the Reunion Main Quest. During the story, the group ventures deeper into Sacrosanctum/Lazlion and they encounter the boss as a Monster protecting the area.
