Indie sensation Vampire Survivors has released its Japanese-themed DLC expansion pack, Legacy of the Moonspell. Like what you expect from an expansion, this release adds eight new characters and 13 new weapons into the game, offering fresh and unique playstyles that will surely add hours to your total playtime. Here’s how you can unlock Mille Bolle Blu, one of the new weapons, and evolve it into Boo Roo Boolle in Vampire Survivors Legacy of the Moonspell DLC.
How to Unlock Mille Bolle Blu – Vampire Survivors Legacy of the Moonspell DLC
To obtain the Mille Bolle Blu, you have to unlock Gav’Et-Oni first since it is his (its?) default weapon. Simply kill a total of 6,000 Kappa enemies or by casting the “CheVolano” Spell in the Forbidden Scrolls of Morbane secret menu to obtain the character. Afterward, buy the weapon from the merchant.
Mille bolle blu is actually an Italian for “A thousand blue bubbles,” which fits with how the weapon works and how kappa (the monster Gav’Et-Oni is based on) is sometimes described as a playful water-dwelling monster in Japanese folklore.
How to Evolve Mille Bolle Blu Into Boo Roo Boolle – Vampire Survivors Legacy of Moonspell DLC
To unlock Boo Roo Boolle, the evolution of Mille Bolle Blu, from the chest, you will have to max out both:
- Mille Bolle Blu to Level 8.
- And the Spellbinder Item to Level 5.
Below is the list of upgrades when you leveled up both the Boo Roo Boolle and Mille Bolle Blu:
| Level | Effect |
| Level 1 | Default |
| Level 2 | Shoots out one additional projectile, base area increased by 10% |
| Level 3 | Cooldown reduced by 0.2 seconds, damage increased by 3 |
| Level 4 | Shoots out one additional projectile, base area increased by 10% |
