Recommended Build 1: Multi-Support Specialization (Max Group Hunt Enhancement)

Example Activated Skills
- Group Hunt Enhancement [Defense]
- Paralysis Follow-up
- Paralysis Attack
- Melody Skills (Earplugs (L) / Attack Up (S) / Divine Blessing)
Usage: In multiplayer, players spread the Earplugs (L) melody to allies, restrain the monster with Paralysis, and boost the entire team’s combat power with Attack/Defense buffs. It is highly effective against monsters with frequent roars, such as Black Diablos.
Alternative Options:
- Consider the Jack-O-Head for the Head slot during the event period.
- For a mix of solo usability, consider swapping the Arms for Espinas to gain Lock On / Partbreaker.
Recommended Build 2: Solo/Damage Focus (General Purpose)
Usage: This build prioritizes versatility, allowing for solo hunting. The player self-supports with melodies, aggressively pursues critical hits with standard attacks, and uses the Paralysis Follow-up skill to land massive damage via Echo Wave attacks while the monster is paralyzed.
Equipment Configuration and Activated Skills
| Part | Armor Name (Skill Unlock Grade) | Equipment Skill |
| Head | Pukei-Pukei Subspecies Head (G8) | Weakness Exploit Lv2, Lock On Lv1 |
| Chest | Barioth Mail (G6) | Charge/Echo Enhancement Lv1, KO Skill Lv2 |
| Arms | Mizuha Sleeves (G8) | Guts Lv2, Chameleos’ Miasma Lv1 |

| Weapon | Hidden Tone+ (G5) | Resuscitate Lv2 |
General Tips
- Priority Upgrades: Prioritize upgrading Paralysis Attack and Paralysis Follow-up to increase Paralysis accumulation and damage during the paralysis duration. When in a group hunt, prioritize Group Hunt Enhancement skills.
- Drifting Melding (Hyouryuu Rensei): Aim for general-purpose damage/survivability skills like Weakness Exploit, Critical Boost, or Health Boost.
- Playstyle: The basic cycle is: Support allies (or self) with melodies → Paralysis unsheath attack → Echo Wave spam. For monsters with frequent roars, maintaining Earplugs (L) allows for safe damage contribution.
- Production: Tickets for the weapon are obtained during the Halloween 2025 event (starting 10/27). Use Upgrade Tickets to lighten the material burden during enhancement.
