In Monster Hunter: World and its Iceborne expansion, upgrading and augmenting weapons is essential for maximizing your hunting efficiency, especially in high-tier quests. Below is a comprehensive breakdown of the weapon upgrade and augmentation processes, detailing the pathways, required materials, and strategic tips for endgame players.

Weapon Upgrades

Base Game (High Rank)

– Upgrade Path via Weapon Tree: At the Smithy, players can enhance their weapons using materials acquired from defeated monsters, mining ores, and collecting bones. This upgrade process is linear, following a defined progression within the weapon tree.
– Capping Out: Before you can augment a weapon, you must complete its upgrade path, which means achieving the maximum possible level on the weapon’s tree. Only after this step is the augmentation option unlocked.

Iceborne Expansion (Master Rank)

– Master Rank Weapons: Transitioning to Master Rank allows for further upgrades using new, more potent materials.
– Weapon Upgrade Tree Expansion: Many weapons introduce new branches or variants at this level. In some cases, Master Rank weapons can be upgraded directly from high-rank variants, while others may require starting from the base level of the Master Rank tree.
– Material Requirements: Each progression tier in Master Rank demands rarer materials sourced from high-tier monsters, tempered monsters, or special quests, making it crucial to engage in tougher hunts.

Weapon Augmentations

Base Game (High Rank)

– Unlocking Augments: Only weapons that are fully upgraded can be augmented.
– Augment Types: Players can apply various augmentations, which include:
– Attack Increase: Boosts weapon damage.
– Affinity Increase: Enhances the chance of landing critical hits.
– Defense Increase: Provides additional defense while using the weapon.
– Slot Upgrade: Adds more slots for decorations, enhancing customization.
– Health Regen: Restores a portion of health when dealing damage.
– Augment Slots: Some weapons can accommodate multiple augmentations, and players can stack these for greater benefits.
– Materials: Augmentations require streamstones specific to each weapon type, which are rare drops from tempered monster investigations.

Iceborne Expansion (Master Rank)

– Custom Upgrades and Augments: After a weapon is fully upgraded in Master Rank, you gain access to new augment options. These augmentations now allow for greater customization and unique enhancements.
– Different Materials: The new augmentations necessitate specific materials from the Guiding Lands, a dedicated endgame area designed for high-level hunting and gathering.
– Augment Categories: New augment options include boosts to elemental or status effects, with the number of augment slots determined by the weapon’s rarity. Players can further upgrade these slots to maximize their options.
– Restored Materials: When upgrading a high-rank weapon to Master Rank, any previously applied augments are removed, and you receive a full refund of the materials used for those previous augmentations.

Endgame Weapon Progression

– Guiding Lands: This area is pivotal for sourcing new augment materials in Master Rank. Here, players can engage with tempered monsters and gather unique resources necessary for advanced upgrades.
– Rarity and Slots: Higher-rarity weapons (Rarity 11 or 12) often begin with fewer augmentation slots but can be modified to include more options through upgrades. Conversely, lower-rarity weapons may start with more slots but require additional upgrades to reach their full potential.
– Augment Stacking: As in High Rank, players can stack the same upgradable augments for enhancements or mix different types to create tailored builds.
