Obsidian Frox

Maren's Tip

Stock up on Hearty meals before boss fights — a single Hearty Durian dish gives full recovery plus bonus hearts. Don't forget to save!

Description

A heavily armored Frox variant encased in dense obsidian plating that resists conventional physical attacks. Found in the more hazardous and Gloom-saturated Depths corridors, it drops superior Zonaite quantities and has a chance to yield Crystallized Charges. Break the obsidian shell with explosive Bomb Flowers or Yunobo's Rock Roar before targeting the eye.

Weakness

Obsidian Frox's primary weakness is Eye on forehead — bomb mouth stun, then mine obsidian ore.

How to Beat Obsidian Frox

1. Obsidian Froxes are an armored variant covered in dark obsidian plating that makes them significantly tougher than standard Froxes.
2. They are found in deeper, more dangerous Depths regions.
3. Preparation: Bring Bomb Flowers (essential), strong fused weapons, Brightbloom Seeds, and healing items.
4. The obsidian armor means weaker weapons bounce off the body — you need weapons with at least twenty to twenty-five attack power to damage the ore deposits efficiently.
5. Phase 1 — Breaking the Armor: The obsidian plating on the Frox's body provides damage reduction for regular attacks.
6. However, the eye remains vulnerable and the bomb-in-mouth stun still works.
7. Wait for the inhale attack and throw a Bomb Flower into the open mouth.
8. The stun duration is the same as a regular Frox.
9. During the stun, climb onto its back and attack the ore deposits — they are obsidian-laced and require stronger weapons to mine.
10. Hammer weapons still deal bonus damage.
11. Phase 2 — Increased Aggression: The Obsidian Frox has additional attacks compared to the standard variant.
12. It performs a ground pound that sends out shockwaves in a wide radius — jump to avoid or maintain distance.
13. It also has a faster charge attack that covers more ground.
14. The tongue grab has better tracking.
15. The inhale attack is still your primary opening.
16. Use it every time it appears.
17. Phase 3 — The Eye: When the Frox is below half health, its eye glows more intensely and it becomes more aggressive, chaining attacks faster.
18. The inhale attack becomes less frequent, forcing you to rely more on eye shots for stuns.
19. Arrow stuns are shorter duration, so you have less time to climb and mine.
20. Prioritize big damage hits on the eye during arrow stuns rather than climbing.
21. The Obsidian Frox drops better materials than the standard variant — more Large Zonaite, occasional Diamonds, and unique obsidian materials.
22. Four to five stun cycles are needed.
