How to Farm Artian Reinforcements in Monster Hunter Wilds: Seed Re-Roll Method and 5-Slot God-Roll Odds

Verified on Version 1.041.00.00 (February 2026). Values may change with future Title Updates.

Monster Hunter Wilds weapon augment farming — or Artian Reinforcement, to use the correct in-game term — is the endgame system that separates a functional weapon from a build-defining one. Five reinforcement slots. Five random bonuses. One very specific combination you actually want.

The problem is that every guide stops at “it’s random, good luck.” This one doesn’t. Below is the seed re-roll method in full, the probability math that tells you exactly what odds you’re fighting, and the fastest Oricalcite farming route to stop running dry mid-session.

If you’re still learning the game’s systems before hitting endgame, our Monster Hunter Wilds beginner’s guide covers the full progression path.

Quick Start: Artian Reinforcement in 8 Steps

Already know the basics and just need the loop? Here it is:

1. Reach Chapter 4 and complete “Wyvern Sparks and Rose Thorns” to unlock Artian weapons
2. Reach HR 40 to access Rarity 8 Artian weapons (the tier worth farming)
3. Farm Tempered Monsters to gather Wyverian Bloodstones
4. Convert Bloodstones at the Suja Melding Pot into Artian crafting materials
5. Stockpile at least 1,250 Oricalcite before starting the reroll loop (5 full attempts minimum)
6. Save your game, then craft and fully reinforce your target weapon (5 levels)
7. If the bonuses are bad, quit to title WITHOUT saving — your materials refund
8. Craft a different Artian weapon first to advance the RNG seed, then retry your target

What Are Artian Weapons?

Artian weapons are Monster Hunter Wilds’s top-tier endgame weapons. They are crafted at the Smithy from three same-rarity Artian components — two Blade (or Disc, or Tube, depending on weapon type) parts and one Device slot — with the weapon’s element determined by whichever component type you use most.

There are three tiers:

• Artian I (Rarity 6) — unlocked after Chapter 4 completion
• Artian II (Rarity 7) — available at HR 30
• Artian III (Rarity 8) — available at HR 40; this is the tier worth farming

Rarity 8 Artian weapons come with three decoration slots, white sharpness, and the highest raw attack values in the game. Reinforcing them is what makes them better than high-rarity monster-specific weapons — the random bonuses can push a Rarity 8 Artian above anything you’d craft from a single monster.

If you’re building around specific weapon types, our Monster Hunter Wilds weapon tier list covers which types have the best Artian payoff.

The 5 Reinforcement Bonus Types — and What a God-Roll Actually Means

Each reinforcement level adds one random bonus from the following pool. Each bonus type has a stack cap — once you hit it, that bonus can no longer appear:

A “god-roll” means all 5 reinforcement slots landed exactly the bonuses you needed. What that looks like depends entirely on your build:

• Raw damage build (Greatsword, Hammer, Longsword): 5× Attack (+25 raw) is the ceiling
• Critical hit build (Dual Blades, Insect Glaive): 3× Attack + 2× Affinity is optimal
• Elemental build: 2–3× Element + 2× Attack gives the best scaling
• Balanced hybrid: 3× Attack + 1× Affinity + 1× Sharpness is widely accepted as “good enough” and far more achievable

Importantly, a 3× Attack + 1× Affinity + 1× Sharpness weapon is roughly 1–2% behind a true god-roll in DPS. For most players, that’s within the margin of a single positioning mistake. Don’t let perfect be the enemy of a very good weapon.

Understanding the Seed Queue — Why Re-Rolling Works

The Artian reinforcement system looks random, but it isn’t truly random in the way a coin flip is. Monster Hunter Wilds uses a pseudo-random number generator (PRNG) to pre-determine your reinforcement sequences. Think of it as a long, pre-shuffled deck of outcomes: when you craft a weapon, the game draws the next five cards in the sequence.

This matters for farming because the sequence is determined before you see the result. Here’s the mechanism:

1. When you craft a weapon, the game reads the next entry in the internal seed queue
2. That entry determines all 5 reinforcement bonuses for that weapon
3. If you reload a save from before the craft, the seed pointer resets to the same position — you’ll get identical bonuses on the same weapon
4. If you craft a different weapon first, you advance the pointer by one entry
5. Now when you craft your target weapon, it draws from a different position in the queue — different bonuses

The save-reload trick is not a glitch. It’s using a documented property of how the game’s RNG behaves: the pointer doesn’t advance until a weapon is crafted and saved.

The Seed Re-Roll Farming Loop

This is the full loop. Do not start it without at least 1,250 Oricalcite stockpiled — each complete reinforce attempt (5 levels) costs 250 Oricalcite, and you’ll realistically need 5–25 tries to hit a good roll.

Preparation (do this once):

1. Decide on your target: which Artian weapon type and which reinforcement god-roll you’re chasing
2. Stockpile materials: 500+ Oricalcite, matching Artian crafting components for both your target AND a cheap throwaway weapon
3. Save your game in a stable location (not mid-quest)

The Loop:

1. Hard save — manual save from the menu, not autosave
2. Craft your target weapon at the Smithy
3. Reinforce to level 5 — all 5 levels in sequence; check bonuses as they appear
4. Evaluate the result:

→ If acceptable: save and equip — you’re done
→ If not acceptable: quit to title screen WITHOUT saving

5. Reload your save
6. Advance the seed — craft one throwaway Artian weapon (pick a cheap type with low material cost) and reinforce it to level 1 (minimum advancement)
7. Return to step 1

Key rules for the loop:

• Never save after a bad roll — the materials are only refunded if you quit before saving
• Advancing by one throwaway weapon shifts the queue by one entry. If you’re still getting similar results after 3–5 attempts, advance by 2–3 throwaway weapons to shift further in the queue
• Each weapon type uses a separate seed track. Crafting a Greatsword to advance the queue does not affect the Longsword sequence

5-Slot God-Roll: The Probability Math

Exact drop rates are not published by Capcom, but the bonus pool allows us to calculate baseline odds. For melee weapons, there are 4 effective bonus types (Attack, Affinity, Sharpness, Element — Ammo Capacity doesn’t apply). Assuming equal probability per type:

Note: These are approximations based on 4 bonus types with equal weighting. If Capcom’s internal weights differ, actual odds may vary. Community testing broadly aligns with the 1/1,024 estimate for pure 5× Attack.

The practical takeaway: chasing a pure 5× Attack roll will cost you roughly 250–375 thousand Oricalcite at the expected value. Targeting “at least 3× Attack” is 100 times more achievable. For most hunting timers, the DPS difference between these two outcomes is under 2%.

Set your threshold before you start farming. Chasing the absolute ceiling without a stopping condition is how you lose 40 hours to the reroll loop.

Farming Oricalcite and Artian Materials

Oricalcite is the primary bottleneck. Each reinforcement level costs 50 Oricalcite, so a full 5-level reinforce costs 250 per attempt. Here’s the fastest way to keep up with demand:

Primary route — Tempered Monsters:

1. Hunt Tempered Monsters (purple map icons) and break their body parts — this yields Wyverian Bloodstones
2. Take Bloodstones to the Suja Melding Pot and convert them into Artian crafting materials
3. Excess monster parts go to the Oilwell Basin Smelting Foundry (“Smelt Ore”) — trade for Oricalcite directly

Material efficiency tips:

• Two-Tempered Monster investigations yield fragments faster than single-monster quests — prioritize co-op or SOS investigations
• Seregios and Lagiacrus investigations convert at a higher Oricalcite-per-part rate when smelted
• Don’t dismantle non-target Artian weapons before checking their reinforcements — they may have better rolls than expected

Our endgame guide covers the full Tempered Monster investigation loop in detail, including which investigations offer the best parts-per-hunt ratio.

Which Player Should Farm How

If you’re a casual or optimiser: accept the first roll that hits your threshold and start hunting with it. The gameplay difference between a 3× Attack roll and a 5× Attack roll is invisible in practice. The hardcore path is for players who specifically enjoy the farming loop, not for players trying to clear content faster.

Gogma Artian Weapons: The Tier Above

Title Update 4 (December 2025, Version 1.040.00.00) introduced Gogma Artian Weapons — a direct upgrade tier above Rarity 8 Artian. To access them:

• Reach HR 100
• Defeat Gogmazios or complete “Ghosts Pay No Heed to Tomorrow”
• Upgrade a maxed Rarity 8 Artian weapon using Tarred Devices from Gogmazios

The key point: all existing reinforcement bonuses carry over. A 3× Attack Rarity 8 Artian becomes a 3× Attack Gogma Artian — you don’t re-roll the base weapon. Gogma Artian then adds one random Set Bonus Skill and one random Group Skill (rerollable via the Amendment system).

Sought-after Group Skills include Lord’s Soul and Lord’s Fury. Set Bonus Skills like Gore Magala’s Tyranny and Leviathan’s Fury are the top targets for most meta builds.

The implication for farming: a 3× Attack roll that you already have is fully viable for the Gogma upgrade path. You don’t need a perfect Artian before investing in Gogma — an acceptable roll gets you into the best content now.

FAQ

Does reinforcing cost materials if I reload a save?

No — if you quit to the title screen before saving after a reinforce, your Oricalcite and other materials are refunded. This is the basis of the entire reroll loop. The cost only becomes permanent once you save.

Can I reroll a weapon I’ve already saved?

No. Once you save after reinforcing, those bonuses are locked permanently. There is currently no in-game system to reroll the reinforcements on an already-saved weapon. The only recourse is to craft a new copy of the same weapon and start the reroll loop fresh.

Is it worth farming a different Artian weapon for each element?

For elemental builds: yes, eventually. Artian weapons of different elements share the same reinforcement bonus pool, so a Fire Artian can roll 5× Attack just like a Water Artian. Start with your primary element weapon, get an acceptable roll, then decide whether the marginal gain from element-optimal reinforcements justifies the farm time for additional weapons.
