Both slots and jewels can have levels – the slot level needs to be the same or higher than the jewel level. If you want to use a decoration on a weapon, you’ll need to upgrade it enough first. When it comes to armor, though, you’ll need to craft the beta version of the desired piece – alfa versions come with two skills, while beta. The latest MHW event is a Monster Hunter movie crossover.

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.
