Gems go into your equipment's **sockets** and add effects to the hero wearing the piece. You keep and work on them in the **Gem Chamber**, inside the Armory.

# Tiers and effects

There are six tiers, from **I to VI**, and a higher tier is worth more. Tier VI doesn't come from the Arcane Vault: it comes from fusing three tier V gems. Each effect's page shows its value per tier and its cap.

Effects fall into three domains:

| Domain | Socket | Effects |
|---|---|---|
| Offensive | Fury | [Attack](https://jds-game.com.br/portal/wiki/gemas/ataque?lang=en), [Crit Chance](https://jds-game.com.br/portal/wiki/gemas/chance-de-critico?lang=en), [Crit Damage](https://jds-game.com.br/portal/wiki/gemas/dano-critico?lang=en), [Penetration](https://jds-game.com.br/portal/wiki/gemas/penetracao?lang=en), [Lifesteal](https://jds-game.com.br/portal/wiki/gemas/roubo-de-vida?lang=en), [Precision](https://jds-game.com.br/portal/wiki/gemas/precisao?lang=en) |
| Defensive | Bulwark | [Defense](https://jds-game.com.br/portal/wiki/gemas/defesa?lang=en), [HP](https://jds-game.com.br/portal/wiki/gemas/vida?lang=en), [Dodge](https://jds-game.com.br/portal/wiki/gemas/esquiva?lang=en), [Block](https://jds-game.com.br/portal/wiki/gemas/bloqueio?lang=en), [Damage Reduction](https://jds-game.com.br/portal/wiki/gemas/reducao-de-dano?lang=en) |
| Utility | Trail | [March Speed](https://jds-game.com.br/portal/wiki/gemas/velocidade-de-marcha?lang=en) |

Some gems carry more than one stat. In that case the gem's value is **split** between them, at a discount: on a two-stat gem, each stat is worth about 40% of what it would be on a single-stat gem; on a three-stat gem, about 21.7%. You gain flexibility, not extra power.

# Sockets

The higher a piece's rarity, the more sockets it has; each equipment page shows how many. The socket's **color** depends on the slot:

- **Fury** (offensive): weapons and gloves.
- **Bulwark** (defensive): helm, chest, boots and belt.
- **Trail** (utility): cloak and mount.
- **Prismatic** (takes any gem): necklace and ring. On Epic and Legendary pieces, the last socket in other slots can also come out prismatic.

A gem only fits a socket of its own domain or a prismatic one. Multi-stat gems and keystone gems only fit **prismatic** sockets.

# What the Forge unlocks

Your [Forge](https://jds-game.com.br/portal/wiki/construcoes/forja?lang=en) level decides the highest tier the Arcane Vault can roll, which effects can come out (basic ones first, advanced ones later), whether two-stat gems can drop, and when cutting and adding an affix open up. The Forge page shows what each level unlocks.

# Fusion

At the **Forge Bench**, three free gems of the same tier become one of the next tier. Fusion works from tier I to V — three V gems become one VI. If two of the three share an effect, that effect carries over; if all three differ, one is picked at random. **Auto-fusion** repeats this in a cascade up to the tier you choose, but stops at V: fusing into VI is always manual.

Only **free** gems go into fusion, manual or automatic. To fuse a gem that's socketed in a piece of gear, unsocket it first.

# Cutting

Cutting spends **Runic Dust**, and the gem must be out of your equipment:

- **Dissolve** breaks a gem down into dust. Higher tiers give more dust, and the gem is gone for good.
- **Cut** swaps the effect of a single-stat gem for another one your Forge has already unlocked.
- **Add affix** gives a single-stat battle gem a second, random battle stat. Utility gems and low-tier gems don't accept it.

Dust costs show right on the screen.

# Limits and diminishing returns

Each hero has a budget of **active** gems: 30 combat, 4 utility and 1 keystone. Socketing more doesn't break anything: the strongest ones stay active and the rest stay installed, with no effect.

Each effect also has a **cap** on the total from the hero's gems. Near it, each extra point is worth less, and past it you get nothing. Stacking a single effect stops paying off; spreading across effects usually does better.

# Keystones

**Keystones** are unique effects that trigger at specific moments in a fight: [First Blood](https://jds-game.com.br/portal/wiki/gemas/primeiro-sangue?lang=en), [Bulwark Thorns](https://jds-game.com.br/portal/wiki/gemas/espinhos-do-baluarte?lang=en), [Bloodsucker](https://jds-game.com.br/portal/wiki/gemas/sanguessuga?lang=en), [King's Breath](https://jds-game.com.br/portal/wiki/gemas/folego-do-rei?lang=en) and [Final Judgment](https://jds-game.com.br/portal/wiki/gemas/juizo-final?lang=en). Each one's page explains its trigger.

They work in army battles and, when the server enables them, in Guild War duels. Colossus duels ignore them. Two complete sets also grant a keystone, which competes for the same slot as gems (see [Sets and relics](https://jds-game.com.br/portal/wiki/guia/conjuntos-e-reliquias?lang=en)).
