Monster Hunter World Iceborne has re-worked the Augment System for weapons. In this guide I will go over the Augment System along with the required materials.

Monster Hunter World Iceborne Augment System Guide

Back in Monster Hunter World, a weapon could be augmented a set amount of times depending on its rarity. Each augment type was weighted the same. In Iceborne, each augment type has a different “weight” or cost assigned to them and each weapon’s socket number is based on rarity. Below you will find each Augment‘s, sockets, costs and limits.

Yellow Text means that it was added in the Rajang update.

Augment’s Socket Usage & Benefit

1. Early on in Monster Hunter World, increasing your Hunter Rank is as simple as completing story missions. However, this will begin to slow down the further into the game you get, but your level.

What Is Augmenting Equipment?

Upgrading Weapons & Armor to Full Potential

Augmenting is a form of upgrade that allows you to further upgrade weapons & armor past their limits, further improving their stats.

Weapon Augments Adds Stat Boosts & Other Bonuses

For Weapon Augments, you can choose to boost stats such as Attack, Affinity & Defense or add an extra slot to the weapon. You can also add a Health Regen stat to your weapon.

Augmenting Armor Allows You To Upgrade More

Augmenting Armor removes the upgrade level cap, increasing the number of times you can upgrade the armor. This allows you to raise the defense stat past its default cap.

How To Unlock Equipment Augmentation

How To Unlock Augmentation Procedure

No.	Procedure
1	Reach Hunter Rank (HR) 30 to unlock encounters with Tempered Monsters.
2	Collect Tempered Monster traces, defeat Tempered Monsters and obtain a 'Streamstone'
3	Talk to the Smithy which will trigger a dialogue to unlock 'Augment Equipment'

Raise Your HR to At Least Level 30

Raising your HR to level 30 will unlock encounters with Tempered Monsters. The required item 'Streamstones' can only be found from Tempered Monsters.

How To Raise Hunter Rank After Story

Hunt & Defeat a Threat Level 2-3 Tempered Monster

After raising your HR, launch a Tempered Investigation quest to hunt a monster with at least Threat Level 2. Streamstones will only drop from these types of monsters, & will be appraised to a 'Warrior Streamstone' or 'Hero Streamstone' after completing the quest.

What Is An Investigation Quest - Tips, Guide & Rewards

Why You Should Augment Equipment

Make Your Weapons Much More Powerful

At the end-game, you will fight far stronger monsters than before, and you'll need higher damaging weapons to quickly take them down. Augmentation greatly improves end-game viability of high rarity weapons!

Relevant Guides On Stats

What Is Attack Power

What Is Affinity

Strengthen Armor To Take On Challenging Hunts

At the end-game, monsters, especially Tempered & Arch Tempered forms, will hit harder, and are vastly more challenging than normal hunts. You'll need the best equipment as possible to take on these hunts.

How To Augment Weapons

Only Rarity Level 6 to 8 Can Be Augmented

Only Level 6 and above weapons can be augmented. As the weapon rarity increases, the less augmentation slots you get.

Rarity	Augmentation Slots

Rarity 7	2 Slots
Rarity 8	1 Slot

Slot Upgrade	Adds an extra Jewel Slot. Stack with another Slot Upgrade to increase the slot's level
