The Vault is a bonus instance, located in the Joker's Funhouse and accessible through the On Duty Menu after level 6. Players can access the Vault once during a certain period based on the type of account:
- Free to Play: Once per week
- Premium: Once every three days
- Legendary: Once per day.
Joker's vault is filled with presents that fall from the ceiling over a short period of time. Breaking open the presents (with 1 hit each) earns the player a prize. Once all the presents are opened, the Vault run ends and the player is prompted to leave. There is no actual time limit, despite the Joker's taunting to that effect. While the prize loot that appears is up to random chance, it is usually appropriate to a player's level; lower levels will rarely receive Epic (purple) loot or Marks , but higher levels do receive lower-level prizes like Uncommon (green) loot.
Balls of various sizes and bombs also drop randomly, causing some frustration as they push players around and obscure vision. Those were completely removed with game update 26 and slightly changed reintroduced with game update 31. Now the presents also can contain liitle Jokandroids.
Every present will drop a small amount of cash depending on player level, with a small chance for Uncommon or Unique style tokens and an even smaller chance for a flavor trinket or other forms of currency.
All prizes are non-tradable.
Clothing merchandise featuring a DC character's logo. Colors are locked, that is not changeable by the player.
There are purple-quality gear drops that in addition to a unique style will also change a character's movement mode while equipped. However, the new movement mode will not have any skill upgrades
- Monitor Propulsion Pack ( Flight ) - as used by the Joker in Legends PVP, particles and sounds included
- Gloves of Clinging (Acrobatics)
- Journeyman's Boots (Super Speed)
- Phantom Zone Kryptonite Chunk - Legendary item that turns you into a ghost with Kryptonian powers.
- Demon Figurine - Transforms you into a demon of Greed (male) or Lust (female).
- Kryptonian Bouncy Sphere - Summons a giant Superman-themed ball that can be thrown around for fun or to damage enemies.
- OMAC Nanite Circuitry - Briefly changes you into an OMAC increasing toughness and health for a short time.
- Manhunter Circuitry - Disguises you as a Manhunter
- Death Blossom Seed - Summons a Death Blossom that aids you in combat for a shot period of time, when it withers, near by allies are healed.
Most of these are only cosmetic changes and have no practical uses. Transformations will last several minutes and can be removed by activating the trinket again. They will also override any active model changes, like the Doomsday form players briefly acquire in Smallville.

The Multi-Use Vault Tickets hinted at by Ambush Bug are available via the in-game Marketplace button as a micro-transaction available for 100 Sony Station Cash (SC) per Single Use Vault Ticket, or 400 SC for a 5 use Multi-Use Vault Ticket.
