How to Spawn the Sans Boss
To farm the required materials, you need to fight the Sans Boss. Steps to Spawn:
- Go to the Dungeon Cave.
- Defeat 20 Skeletons.
- The Sans Boss will spawn automatically.
This method is repeatable, so you can continuously farm for drops.
Sans Boss Drops (All Phases Explained)
The boss has two phases, each with slightly different drop pools.
Phase 1 Drops:
- KR Manifest
- Blue Soul
- Bad Time Eye
- Gaster Blaster
- Eternal Bones
Phase 2 (Glitch Phase) Drops:
- Grinning Void
- Blue Soul
- Bad Time Eye

If you are specifically farming Pieces of the Void or Grinning Void, Phase 2 is crucial.
How to Get Mysterious Connection (Secret Questline)
One of the most important items, Mysterious Connection, does not drop from the boss. It comes from a hidden NPC quest.
- Hidden NPC: Gastra
- Location: Wandon
- Interaction locked behind objectives
You must complete two main challenges.
Step 1: Stability Test
Requirements:
- Tank 1,000,000 total damage

You must not move during this test. If successful, Gastra becomes interactable.
Step 2: Memory Check
You must find the Shadowy Soul.
- Spawns during specific server times
- Location: Endless Castle
- Look for a Shadowy Soul orb
After finding it, return to Gastra again.
Step 3: Gastra
Interact with Gastra at night. Rewards:
- Mysterious Connection
- Mystery Man Title
Now you have one of the key items needed for Sans.
Extra Rewards & Cosmetics
When you unlock Sans:
- You automatically receive the Lazy Skeleton title.
- The Sans Boss can drop the Lazy Bone Mask accessory.
If you want full cosmetic completion, keep farming even after unlocking Sans.
Sans Moveset Overview
Sans focuses on ranged pressure and burst damage.
- Skills feel fast and spammable
- Strong mid-range damage
- F Move activates a mode that grants a damage boost
However, there is one important limitation.
Is Sans Worth Unlocking?
Sans requires significant farming and a hidden questline, making him one of the more effort-heavy unlocks in Verse Piece. If you enjoy:
- Boss farming
- Secret objectives
- High-skill characters
- Rare cosmetic titles
Then Sans is absolutely worth grinding for.
Unlocking Sans is not just about damage output. The process involves boss mechanics, rare drops, and a secret NPC challenge that tests both survivability and patience. If you plan your farming properly and focus on completing objectives efficiently, you can unlock Sans without unnecessary grinding. Once obtained, he becomes a strong ranged character with solid burst potential and exclusive rewards tied to his progression. For players looking to stay competitive and collect everything the update offers, Sans is one of the most rewarding additions in Verse Piece so far.
