Gearing System
For in-depth details about how Gears work in Blue Protocol: Star Resonance, check out our Gearing System guide here:
Upgrading Gear
The NPC Maxim will feature all Gear upgrading mechanics, from reforging to refining and embedding. He will also let you dismantle old gear, allowing you to reuse old resources for your freshly farmed gear.
Reforge & Perfection

Reforge is the first gear upgrade system, and will enhance the Perfection level of your equipment. You must consume Reforge stones - obtainable through various game modes, including Dungeons - to upgrade the Perfection score.
When upgrading the Perfection of a piece, it is directly linked to that piece and cannot be transferred to another. However, the Dismantle function will allow you to recuperate most of your Reforge stones.
Lastly, the Reforge system also unlocks a third random but re-rollable Advanced Attribute on every item slot. It follows all the same rules of the items' usual Advanced Attributes, but offers far fewer stats and can be changed randomly by spending Reforge Stones to change it. When reaching the Perfection cap, you may spend additional Reforge stones past the cap to search for your desired stat on this final line.
Embedding & Gems
Each Gear piece can accommodate one Gem via the embed system. Each gem provides both Basic and Advanced attributes. Gems have different Levels, with higher levels yielding increased stats and bonuses.
There are 4 Gem types: Ruby, Sapphire, Emerald, and Diamond, and 4 Gem cuts: Square, Triangular, Fancy, and Pear. Gemstone colour determines the Primary Attribute while the gem cut changes the Advanced attribute it grants.
Gem Type/Gem Cut | Ruby | Sapphire | Emerald | Diamond |
---|---|---|---|---|
Triangular | Crit Strength | Haste Strength | Mastery Strength | Luck Strength |
Square | Crit Stamina | Haste Stamina | Mastery Stamina | Luck Stamina |
Fancy | Crit Agility | Haste Agility | Mastery Agility | Luck Agility |
Pear | Crit Intelligence | Haste Intelligence | Mastery Intelligence | Luck Intelligence |
Embedding a gem into a gear piece costs


When embedding higher-level gems into higher levels of gear (e.g. Lv 3 Gem into Level 60 gear), you’ll notice a change in the embedding interface. At this point, you’ll have a chance to upgrade gems you embed up to 2 levels higher, improving their stats significantly. You’ll also gain access to an additional embedding option, allowing you to spend more

Refining
Finally, we have the Refine system, which allows you to upgrade each of your gear slots. These upgrades are not tied to the item but to the slot that the item occupies. This means any upgrade to that slot will persist even if you change the gear any number of times.
Refining a gear slot will cause it to grant you stats; the stats you gain are dependent on the gear slot refined.
- Helmet, Armor, Gauntlets, Boots, Bracelet L/R
- Stamina + Refined Armor
- Weapon, Earrings, Necklace, Ring, Charm
- Refined ATK
Each of these stats is powerful and absolutely something you’ll want, but Refined ATK specifically holds very high value. You can see how Refined ATK interacts with damage in our Damage Formula Guide.

Every Refine level requires an increasing amount of resources; different gear slots also need different materials. Each refinement will require:
- Starforge Crystals (Limited Availability)
- The Correct “Mystic Metal”
- Bound Luno
Tip
We suggest buying all the Starforge Crystals possible early on, as it is a rare, limited and highly demanded resource.
At low Refinement levels, the success chance of each upgrade will be 100%, but starting from Level 5 → 6, the chance will start decreasing. The higher the level you reach, the greater the penalty for success. E.g. when refining from Level 13 → 14, the success chance is only 65%.
Failing a refinement will waste all resources involved; fortunately, there is a way around this with the Blessing system. By inserting “Buri Mech Shards” and/or “Moss Mech Shards”, you may increase your refinement success chance back to 100% eliminating failure.
Tip
Mech shards are craftable by players, while Starforge Crystals are not. We recommend relying on Mech shards to guarantee refinements instead of gambling.

Modules
Modules are an endgame gearing system that grant incredibly powerful set bonuses when assembled correctly. While included in gearing they are far more complex than systems covered so far, because of this they have their own dedicated guide you can check out.
