How to Unlock Sonia in Vampire Survivors

Sonia is an unlockable character in Vampire Survivors that requires completing a specific sequence of tasks. This guide will walk you through the exact steps needed to unlock this character, from defeating a boss to collecting the necessary items.

Getting Started: The Castlevania Stage

Begin by selecting the Castlevania stage. Once you’ve loaded in, head straight east toward the castle entrance.

Summoning and Defeating the Bat Boss

Navigate inside the castle and locate the circle sign on the ground. Step on this circle to summon the bat boss.

Defeat the bat boss to obtain the Stallion Gate reward.

Unlocking the Heart Refresh Item

The Stallion Gate is a crucial unlock—it allows heart refreshes to materialize during gameplay. This essentially unlocks the heart refresh item pickup mechanic, making these items visible and collectible.

Collecting Seven Heart Refreshes

With the heart refresh item now unlocked, your final task is to collect seven heart refreshes throughout your runs. Heart refreshes appear as pickups during gameplay—collect a total of seven to unlock Sonia as a playable character.

Once you’ve collected all seven heart refreshes, Sonia will be unlocked and ready to play.

Summary

Unlocking Sonia in Vampire Survivors is straightforward: play the Castlevania stage, defeat the bat boss to unlock the Stallion Gate (which enables heart refresh pickups), then collect seven heart refreshes across your runs. That’s all there is to it!
