Monster Hunter Wilds Decoration Farming Guide

The New Decoration System — Two Types, Two Rules

The decoration system in Wilds works differently from previous Monster Hunter games. There are now two separate categories of decorations, and they follow different rules for how you get them.

Weapon Decorations — Slot into your weapon’s decoration slots. These modify your weapon’s offensive capabilities.

Armor Decorations — Slot into your armor pieces. These handle defensive skills, utility, and comfort.

You can’t mix them. A weapon deco won’t fit in an armor slot and vice versa. This means your farming approach depends entirely on which type you need.

The Big Rule: Craftable vs. RNG

Here’s what most guides get wrong about Wilds decorations:

Single-skill decorations are craftable. If a deco has one skill on it, you can craft it deterministically at the smithy. No RNG, no luck — just bring the materials and make it. This covers the majority of decorations you’ll need for basic builds.
Dual-skill decorations are RNG-based. These are weapon decorations only, and they pack two skills into one slot. You get these from the Melding Pot or as random investigation rewards. This is where the grind lives.

If all you need is a single Attack Jewel or a single Tenderizer Jewel, just craft it. Save your sanity for the dual-skill combos.

When Does Decoration Farming Actually Start?

You can slot basic decorations during Low Rank, but real farming doesn’t begin until you’re deep into High Rank. Push through the 6-chapter story first (Chapters 1-3 are Low Rank, 4-6 are High Rank). Don’t waste time grinding Low Rank investigations for decos — the story pushes you through fast enough that anything you farm gets replaced.

The key milestones:

HR 41 — Melding Pot Tier 1 unlocks in Suja. This is when you can start melding for dual-skill weapon decorations.
HR 100 — Melding Pot Tier 2 unlocks. Higher-tier melding with access to the best dual-skill decorations in the game.

Crafting Single-Skill Decorations

For single-skill decos, talk to the smithy. You’ll see a full list of craftable decorations. Each one requires specific monster materials — usually from the monster whose gear shares that skill.

This is deterministic and straightforward. Need Weakness Exploit? Craft a Tenderizer Jewel. Need Critical Eye? Craft an Expert Jewel. The materials are usually a mix of the target monster’s parts plus some common crafting resources.

Priority craft list (make these first):

Tenderizer Jewel (Weakness Exploit)
Expert Jewel (Critical Eye)
Critical Jewel (Critical Boost)
Attack Jewel (Attack Boost)
Charger Jewel (Focus) — if you play GS, LS, SA, or CB

These five cover the skeleton of every damage build in the game. Craft them before worrying about anything else.

Farming Dual-Skill Weapon Decorations

Dual-skill weapon decos are the endgame grind. These combine two skills in one slot — like Attack Boost + Weakness Exploit in a single decoration — and they’re only available through RNG.

The Melding Pot in Suja

Talk to the melding NPC in Suja to access the Melding Pot. You feed it materials and decorations you don’t need, and it spits out random results.

Tier 1 Melding (HR 41): Produces basic dual-skill weapon decorations. The pool is smaller but the costs are lower. Good for filling gaps in your build.

Tier 2 Melding (HR 100): Produces the best dual-skill weapon decorations in the game. Higher material costs, but the potential rolls include every top-tier combo.

What to feed the pot: Recycle duplicate decorations and excess monster materials. Every skill caps at a certain number of points — once you hit the cap, extra copies of that deco are pure melding fodder.

Investigation Farming for Decorations

Investigations are repeatable quests with bonus reward slots. The good ones drop decorations alongside monster materials. Here’s what to focus on:

Save investigations with decoration icons in the reward pool. Check before you start — the reward list shows what type of loot each investigation can drop.
Multi-monster investigations tend to have larger reward pools. More monsters means more loot lines.
Tempered monster investigations are worth running for decoration farming because Tempered hunts drop Artian materials AND can roll decoration rewards. Don’t skip them.
Generate new investigations by tracking monsters in Windward Plains, Scarlet Forest, Oilwell Basin, Iceshard Cliffs, or the Ruins of Wyveria. Pick up tracks, ride your Seikret along patrol routes, and check your investigation board after every hunt.

Run your saved investigations until you exhaust their uses, then generate new ones.

Priority Decorations to Target

Not all decorations deserve equal grind time. Here’s what to prioritize for endgame builds:

Tier 1 — Build-Defining (Craft These First)

Tenderizer Jewel (Weakness Exploit) — Affinity bonus on weak/wounded parts. The foundation of every damage build.
Expert Jewel (Critical Eye) — Stack until you hit 100% affinity on wounded parts when combined with WEX. Don’t go over.
Critical Jewel (Critical Boost) — Makes your crits hit harder. You want max level.
Attack Jewel (Attack Boost) — Attack Boost 4 is the sweet spot for the affinity bonus.

All of these are single-skill decos, meaning you can craft all of them. Don’t waste melding resources here.

Tier 2 — High Value (Meld or Farm for Dual-Skill Versions)

Dual-skill combos of the above — Attack + WEX, Crit Eye + Crit Boost, etc. These are the real prizes from the Melding Pot.
Crit Element decorations — If you run elemental weapons (and you should for most matchups in Wilds).
Elemental Attack Jewels — Fire, Water, Thunder, Ice, Dragon. For dedicated elemental builds.
Charger Jewel (Focus) — Speeds up gauge fill for Great Sword, Long Sword, Switch Axe, and Charge Blade.

Tier 3 — Comfort and Survivability

Vitality Jewel (Health Boost) — Extra HP is never wasted in Arch-Tempered content.
Steadfast Jewel (Stun Resistance) — Prevents stun-locks that lead to carts.
Resistance Jewels — Swap these in for specific elemental matchups (e.g., Thunder Res for Rey Dau).
Wide-Range Jewels — For multiplayer support builds.

Tips to Speed Up Your Grind

Craft single-skill decos first. Seriously. Half the decorations people grind for through RNG can just be crafted at the smithy. Check before you start melding.
Bulk recycle at the Melding Pot. After every 5-6 investigation runs, dump your duplicate decorations. Don’t hoard them.
Tempered investigations are dual-purpose. You get Artian materials AND decoration rolls. Two birds, one hunt.
Check the investigation board after every hunt. New investigations generate from your tracking data, and good ones disappear if you don’t save them.
Focus your Tier 2 melding at HR 100. Tier 1 melding is fine for early dual-skill decos, but the really powerful combos only show up in Tier 2. Save your best materials for after you hit HR 100.
Don’t burn rare materials on Tier 1 melding. Use common monster parts and duplicate decos. Keep your Tempered materials for Tier 2.

The Meta Build Skeleton

The meta build for nearly every weapon type in Wilds looks like this:

Weapon Skills (via weapon decos): Weakness Exploit 3 + Attack Boost 4 + Critical Boost 3 + enough Critical Eye to hit 100% affinity on wounds.

Armor Skills (via armor decos): Health Boost, Stun Resistance, weapon-specific skills (Focus for GS, etc.), comfort skills for the matchup.

Craft the single-skill versions of the damage decos first. Then grind the Melding Pot for dual-skill weapon decos that let you fit more skills into fewer slots. That’s the path from “functional build” to “optimized build.”

Summary

Craft your single-skill decos at the smithy — no RNG needed. Push to HR 41 for Melding Pot Tier 1 and start rolling for dual-skill weapon decos. Farm investigations for decoration rewards and melding fodder. Hit HR 100 for Tier 2 melding and the best dual-skill combos. Prioritize Weakness Exploit, Critical Eye, Critical Boost, and Attack Boost above everything else. That’s the fastest path to a complete endgame build.
