Intro
Arveld marks the end of the mid game with the battle being quite technical it takes a few tries unless you have prepared quite well. In the fourth biome at the end of the map we find Malzeno guarding the Sacrosanctum after which we have to face Arkveld. This fight can be difficult especially if you have reskilled Ratha and have missed the Mega Demondrug in the loot chest at the entrance.
Loadout
Player Armour:
Diablo Nero Armor (Black Diablos)
Instigator Gem (Since 1v1 can be countered)
Also to divert any attention away from Ratha
Yeti Hammer I (Goss Harag)
Ratha:
Savage Fireball (Remove any other lesser Active skills to conserve
Stamina)
Ratha will use Power Attack or Second Wind the lesser skills you have
Environment Skills: Hardiness + Resonance (From Excursions)
Items:
Mega Demondrug (Very Important) + Vitality Essence
Teammate: Gaul (Free Heals and Vitality + Debuff on enemy)
Note: A speed skill on Ratha will help you win most of the 1v1s which will be really helpful.
Phase 1
Basically with this setup we keep hitting the head to score big points on the Wyvernfall gauge. Destroying the head also reduces Arkveld’s attack power which is required since the fight progresses you might fall short of vitality essences.
Arkveld’s States
Normal Form: Technical Stance (Counter with Power stance)
Enraged Form: Power Stance
Note: A speed skill on Ratha will help win 1v1 but since we have Gaul he will restore
our vitality
Attack till turn 6 and use Mega Demon drug on Ratha (Without this Savage Fireball
won’t trigger phase 2 and Arkveld will keep being aggressive. This is usually indicated by Odgen and the dialogue will inform you that Ratha should use the Savage Fireball skill.
Hammer is used to break the head first since won’t have enough firepower to break the
wings unless we have farmed monsties in the Sacrosanctum biome
Breaking the Head reduces Arvelds’s firepower.
Phase 2
Hammer is very good here since it helps increase or decrease the Wyvenfall gauge very quickly. It even helps prevent Arkveld getting enraged since the hammer can overfill the gauge which shortens the gauge. Always keep the Vitality at two hearts for the Main Character.
Location of the Mega Demondrug

At the entrance door of the Sacrosanctum immediately towards the left is a treasure chest in which you will find the Meg Demondrug
