Vault

A  **Vault** is a small area hidden within some levels behind a cracked wall, containing various treasures and challenges to face. A player with  Exploration can shoot at the cracked wall to open a portal into the vault. This will notify all players.

Most vaults contains a treasure chest at the end, which rewards the player with an Occult Scroll if they defeat all enemies or successfully complete any parkour (boulder dodging, trap avoiding, platforming) in the vault.

Each non-boss stage will usually have 1 vault, but will very rarely have 0 instead. During Daily Challenges, stages will occasionally have 2 vaults.

There are 4 different types of vaults:

* **Non-Fighting Vaults**: No enemies are found here. Instead players must either move past various hazards, or jump over gaps.
* **Fighting Vaults**: Players must fight normal enemies. Sometimes the vault has a challenge event.
* **Elite Vaults**: Players must fight normal enemies, then an elite enemy. The elite enemy is usually assisted by more normal enemies.
* **Special Vaults**: Players are given a special objective, such as defeating a certain target, avoiding additional dangers or preventing something from happening.

Non-fighting vaults become considerably easier with high  Movement Speed. Some jumps become easier when  Dashing at the right time.

* Each hero has a different base movement speed.  Crown Prince has 5.0,  Ao Bai,  Tao and  Qian Sui have 5.2,  Qing Yan has 5.5 and  Lei Luo has 6.0.
* Qing Yan's  Leap allows him to move forward great distances.
* Lei Luo's  Fatal Current increases speed by +30%.
* Qian Sui's  Agile Titan increases total speed by +10%. Additionally  Fierce Charge greatly enhanced his distance traveled.
* Equipping the  Foundry ensures there is no decrease in movement speed based on weapon selection.
* If available,  Flowing Light and  Poisonous Ghost have higher movement speed than Foundry and should be equipped instead.  Fire Tower also counts with the  Breacher talent.
* Resolute +  Flesh and Bones increases speed by +50%.
* Tactical Reload increases speed by +30% while reloading.
* Brief Respite and  Windrider can negate damage when used at the right time.
* Abnormal Speed increases speed by +30% at maximum shields.
* Improved Clip increases speed by +25% until the next reload.
* Strategic Advantage increases speed by +40% for a short time after dashing.
* Propulsion Device gives extra dashes to get away from certain situations.
* Ostrich Rider increases speed by +50%, but increases  Dash cooldown by +300%. This can make some jumps more difficult or take longer.
* Heavy Shield decreases speed by -10% upon taking a hit, and should be dropped until the challenge is completed.
* Old Battle Boots decreases speed by -10% and cannot be dropped, increasing difficulty.
* Heavy Burden decreases speed by up to -20% based on maximum  Health? and  Shields?/ Armor?, increasing difficulty.

Some vaults contain additional rewards:

* Some non-fighting vaults contain a second chest, which is usually found by taking a more difficult path.
* Elite vaults will randomly reward players with weapons, an occult scroll or a  Goblet upon killing the elite enemy.

After leaving a vault, the player needs to wait a few seconds before being able to enter again. Upon re-entering:

* Non-fighting vaults remain unchanged.
* Fighting vaults will have enemies moved to their starting locations. Enemy health remains the same from last leaving.
	+ In solo play, the player can leave the vault during fight, take a rest and restock ammo and shield, then return to clear remaining enemies.
* Any timed events (hard route in non-fighting vault, or Dragon Qian and Guard Seal in special vault) keep their progress.
