Dhoulmagus's first form is a significant challenge, marking a turning point in the game's difficulty. He is a powerful magic user with high offensive capabilities. This battle takes place after a long dungeon, so ensure your party is fully healed and has ample MP before engaging.

Strategy:
- Party Setup: Hero (Swords/Courage), Yangus (Axes/Humanity), Jessica (Staves/Sex Appeal), Angelo (Bows/Charisma).
- Attacks: Dhoulmagus uses powerful single-target and multi-target spells like Frizz, Sizz, and Crackle. He can also use 'Wave of Disruption' to remove all positive status effects from your party, and a strong physical attack.
- Weaknesses: None explicitly, but he is not resistant to physical attacks.
- Hero: Focus on healing with Midheal/Healmore and dealing damage with Falcon Slash. If Wave of Disruption is used, reapply buffs if possible.
- Yangus: Use Helm Splitter to try and lower Dhoulmagus's defense. Otherwise, use powerful Axe attacks like Hatchet Man or Executioner. Use Kabuff if you have it and it's not removed.
- Jessica: Unleash your strongest offensive spells (Frizz, Sizz, Crackle). Keep her MP high with Magic Water.
- Angelo: Primarily focus on healing with Multiheal. Use Oomph on Yangus or the Hero if you have a free turn. Use Bow attacks for extra damage.
- Items: Stock up on Strong Medicines, Special Medicines, and Magic Waters. Yggdrasil Leaves are crucial for reviving fallen allies.
This is a battle of attrition. Keep your HP high, especially after Dhoulmagus's multi-target spells. Be prepared for Wave of Disruption and reapply buffs when safe. Focus on consistent damage and don't let your healers run out of MP.
