# Chests and odds

> The equipment and gem vaults, the bad-luck meter, the 10-pack guarantee and what each reward chest can bring.

Heroes · https://jds-game.com.br/portal/wiki/guia/baus-e-chances?lang=en

There are two kinds of chest in the game:

- **vaults**, which you open with cash on the **Chests** screen (under **Army**);
- **reward chests**, which come from quests, achievements, events and the Shop, and go to your bag unopened.

Each vault's exact odds are on the vault screen itself, under **Detailed odds**, and on the wiki's item pages.

# The vaults

- **Armory Vault**: rolls a piece of equipment, from Common to Legendary.
- **Arcane Vault**: rolls a gem. The highest tier and the possible effects depend on your [Forge](https://jds-game.com.br/portal/wiki/construcoes/forja?lang=en) level; with a low Forge, the vault never goes past its ceiling.

You can open one at a time or ten at once, at a discount. Prices show on the buttons. The Armory Vault needs backpack space for the new pieces.

## The bad-luck meter

Each vault has a **meter** (the *pity*) that rises with every opening that misses the top prize and resets when it drops. The meter is per account and doesn't fade over time:

- **Armory Vault**: a **Legendary** guaranteed within at most **100** openings. After **80** openings without a legendary, the legendary chance starts rising with each new opening. That's the **soft pity**.
- **Arcane Vault**: a **tier IV** gem guaranteed within at most **80** openings, with soft pity after **60** openings. The meter resets when a gem of that tier or higher drops. If your Forge doesn't unlock that tier yet, the guarantee delivers the best gem it allows.

## The 10-pack guarantee

Ten openings at once in the Armory Vault always bring **at least one Rare piece or better**: if the rolls don't include one, the first piece becomes Rare. The Arcane Vault has no such guarantee.

# Reward chests

They wait unopened under **Consumables** in the Armory, and you open them whenever you like. With a full backpack, you can't open equipment chests.

- **Common Chest**: a simple piece that never goes above Rare.
- **Chest of Fate**: a gamble. It can bring anything from a Common piece to a Legendary one, which is extremely rare; when no piece comes out, you get silver as consolation.
- **Armory Chest**: always an **Epic** piece, in a random slot. Some slots come up less often than others.
- **Category chests** (Weapons, Armor, Jewelry and Mount): sold in the **Shop**. They bring an Epic or Legendary piece for a slot in that category.
- **Guild War Chest**: bronze and silver, no item.

Don't mix up the **Armory Chest**, which is a reward, with the **Armory Vault**, which you open with cash. The Wolf and Scorpion set chests work differently: see [Sets and relics](https://jds-game.com.br/portal/wiki/guia/conjuntos-e-reliquias?lang=en).
