Weaknesses: Water, Ice

Recommended Level: 10-12

Ignis Rex is a large, fiery Golem-type monster that serves as the guardian of the Circle of Temper. Its attacks are primarily fire-based, including powerful single-target fire breath and an area-of-effect (AoE) fire attack that can hit your entire party. It also has a strong physical attack.

Strategy:

  1. Team Composition: Bring monsters with strong Water or Ice spells (e.g., Slime, Dracky with Ice skills, or a synthesized monster with 'Sizz' resistance). A monster with healing spells is highly recommended.
  2. Phase 1 (100%-50% HP): Ignis Rex will primarily use 'Sizz' or 'Sizzle' spells and physical attacks. Focus on exploiting its Water/Ice weakness. Use 'Sap' or 'Kasap' if you have a monster that can lower its defense. Keep your party's HP above 50% at all times.
  3. Phase 2 (Below 50% HP): Ignis Rex will become more aggressive, occasionally using a powerful AoE fire attack called 'Blaze'. This attack can deal significant damage to your entire party. Prioritize healing after this attack. If you have a monster with 'Insulate' or 'Magic Barrier', now is the time to use it to reduce magic damage. Continue to chip away at its HP with Water/Ice attacks.

Rewards:

  • Experience Points
  • Gold
  • Fire Crystal (Synthesis Material)
  • Unlocks access to the Whispering Woods

Ensure your monsters have at least 100 HP and 50 MP for your primary spellcasters. Stock up on Medicinal Herbs and Magic Waters. If you're struggling, consider synthesizing a monster with higher Water/Ice affinity or grinding a few more levels in the Circle of Temper.
