Anime Vanguards Update 6.5 just dropped, and one of the biggest additions is the new secret unit: Slime, also known as Rimuru. In this guide, we’ll walk you through how to unlock this powerful unit, what to expect from the challenge, and what you’ll need to evolve him. If you’re trying to add Slime to your collection, here’s everything you need to know. Also check out our Anime Vanguards Codes & Anime Vanguards Tier List.
How To Get The Secret Slime Portal
The Slime (Rimuru) unit is tied to a brand-new secret portal available in Update 6.5. This secret portal isn’t available from the start—it drops from the Spring Portal Tier 10, and the chance to obtain it is 0.5%. That means farming this portal will take time and luck, so patience is key. Here’s how to farm the portal:
- Play Spring Portal up to Tier 10.
- Each clear has a very small chance (0.5%) to drop the Secret Slime Portal.
- Once you have the portal, you can start the Slime challenge.
How good is the Anime Vanguards Slime.
What to Expect From the Slime Portal
- The fight itself is straightforward.
- Visual effects can get overwhelming—feel free to turn them off.
- Rewards are not guaranteed—getting Slime at the end is based on RNG, and not all players will receive him even after completing the portal.
Slime Evolution Requirements
Once you unlock Slime (Rimuru), you can evolve him—though you’ll need to grind a bit more to do so. Here’s what you’ll need:
- Anti Magic Mask
- Shamrock
- Green Essence Stone
- Blue Essence Stone
- Red essence Stone
- Rainbow Essence Stone
Interestingly, once you unlock the unit, you already receive the mask needed for evolution. No need to craft it manually.
The Slime unit in Anime Vanguards Update 6.5 is a great addition, especially for Rimuru fans. While the drop rate from the portal is low, the actual portal fight is manageable, making this one of the more accessible secret units for casual players. Make sure to keep grinding Spring Tier 10 until the portal drops, and don’t forget to stockpile your flowers for evolution.
If you’re planning to evolve or showcase Slime, you’re not alone—many players are curious to see what the evolved version can do. Stay tuned for more guides and showcases on the latest updates in Anime Vanguards.
