What Is the Vaulted Event in Plant vs Brainrots?
The Vaulted Event is a limited-time progression event built around secret spawns, clue hunting, and planting mechanics. Throughout the event, players must interact with a special Brainrot and mysterious tiles inside their garden to unlock rewards.
Key features of the Vaulted Event include:
- A 25-tier reward track
- Clue-based progression
- A hidden vault with an obby challenge
- Exclusive plants, Brainrots, and gear
How to Start the Vaulted Event
To begin progressing in the Vaulted Event, you need to encounter the new Key Brainrot, also known as Keylina.
- Every few minutes, Keylina spawns in the game
- Defeat Keylina when it appears
- After being defeated, Keylina drops clue tiles for your garden
These clue tiles are essential for progressing the event and should not be ignored.
How Clue Tiles and Mystery Spots Work
After defeating Keylina, you will receive special clue tiles.
Using Clue Tiles
- Place the clue tiles in your garden
- These tiles reveal hidden ??? spots
- Planting seeds on the ??? tiles unlocks progress
Important to note:
- ??? tiles can sometimes appear randomly without defeating Keylina
- Planting on ??? tiles unlocks one tier in the Vaulted reward track
This means consistent planting and clue usage is the fastest way to progress.
