Only Fully Upgraded Weapons Can Be Augmented

How To Increase Augment Slots Mhw Quest

The same way it works in MHW, augmentation on weapons can only be done when they are fully upgraded. This means having the weapon at the end of its weapon tree.

Augmentations Now Have Augment Slot Cost

In Iceborne, all available augmentations will now have slot costs. The more augment slots your weapons have, the more augmentations you can put into it.

Master Rank Weapon Augment Slot Costs

Augment	Effects	Cost
Extra Slots	Adds more augment slots on weapon	-
Attack Increase	Slightly increases attack power of weapon	3
Health Regen	Slightly recovers health when damaging monsters	3
Slot Upgrade	Adds a Level 1 slot into weapon	3
Affinity Increase	Slightly increases affinity rate of weapon	2
Defense Increase	Defense is slightly increased with chance of reducing damage	1
Element/Status Effect Up	Slightly increases power of elements & status effects	1

Extra Slots Adds 2 More Augment Slots

When you augment your weapon with Extra Slots, you'll get 2 additional augment slots. This doesn't fill up any augment slot but costs rare materials & some Research Points.

Strengthen Master Rank Weapons With Custom Upgrades

Another new feature of Iceborne, weapons now have custom upgrades. Using specific mods, you can slightly increase specific stats of your weapon & also change their appearance. More mods are unlocked when you keep upgrading a weapon.

Custom Upgrades List

Mod	Effect
Kulu-Ya-Ku Mod	Slightly increases affinity
Pukei-Pukei Mod	Slightly increases elemental or status effect damage
Barroth Mod	Slightly increase attack
Hornetaur Mod	Slightly increases defense

Recommended Master Rank Weapon Augments

Best Master Rank Weapon Augment Chart

Elements	Description
Health Regen	★★★- Recovers health when damaging monsters - Reduces need to use recovery items, therefore increasing time to attack monsters
Affinity Increase	★★・- Increases affinity by 10% - 2nd augment increases by 5% - Best for weapons with low affinity
Attack Increase	★★・- Increases weapon attack power - Increase depends on weapon type - Recommended for weapons with high affinity
Slot Upgrade	★・・- Adds 1 decoration slot - Best for weapons lacking slots
Defense Increase	★・・- Increases defense and has chance to reduce damage - Low priority augment as defense should be armor-focused

Focus On Health & Affinity Augments

It's best to augment weapons with Health Regen & Affinity Increase as these work make hunting more efficient. If your chosen weapon already has a high affinity rate, it's best to use Attack Increase instead.

Choosing Between Attack Or Affinity Increase

Prioritize Weapons With Low Affinity

Having a weapon with high affinity will increase your chance of dealing critical hits & doing heavy damage so it's best to raise the affinity rate of your weapons. However, note that Affinity Increase augments have diminishing returns.

Use Attack Increase With High Affinity Weapons

If your weapon of choice already has a high affinity or cannot be augmented with Health Regen, you can opt to augment it with Attack Increase. This will strengthen your raw attack stat, making each hit more powerful!

About Iceborne Master Rank Weapon Augmentation

Unlocks After Main Story Of Iceborne

Augmenting Master Rank weapons will be unlocked when you complete Iceborne's main story quests. You'll gain access to the Guiding Lands after, the area where you can find most of the materials for Master Rank weapon upgrading.

WARNING! High Rank Augments Will Disappear

If you've already augmented your weapon in Monster Hunter World and decide to upgrade and augment in Master Rank, your augments will disappear. You'll get your materials back, however, augments from High Rank may be crucial in early game Master Rank.

Augments Use Monster Materials From Guiding Lands

Master Rank weapon augments don't use Streamstones anymore, however, they do cost valuable Research Points and need rare materials from the Guiding Lands - the end-game endless hunting area in Iceborne.

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.
