How to Get Rimuru Full Guide
Rimuru is the highlight of this update, but unlocking it requires multiple steps and some grinding:
- Slime Race
- 7x Slime Core
- Shizu Mask
- 10 Slime Essence
- 5 Mil Coins
- 10k Gems
Step 1: Go to Fossil Island
Start by heading to Fossil Island. This is where the Rimuru NPC and boss system are located.
Step 2: Collect Slime Orbs
Slime Orbs are the main requirement to begin farming Rimuru. You can get them from:
- Hollow mobs (around 1% drop rate)
- Exchange NPC (trade items for orbs)
This part can take time, so expect some grinding here.
Step 3: Spawn Rimuru Boss
Once you have Slime Orbs, go to the boss spawner on Fossil Island.
- 1 Slime Orb = 1 Rimuru boss spawn
- Boss spawns every 5 minutes
- Adding more orbs won’t reduce the cooldown
This means you’ll need patience, even if you have a lot of orbs saved.
Step 4: Farm Boss Drops
The Rimuru boss drops the materials needed to unlock the spec. You’ll need to repeatedly defeat it until you gather all required items.
How to Unlock the Slime Race
Before you can fully use Rimuru, you also need the Slime Race. To get it:
- Consume slime items
- Each attempt has a 2.5% chance
This part is RNG-heavy, so it might take multiple tries. After unlocking Rimuru, you still need to level up its mastery. There’s a dedicated NPC that gives quests for progression. Early quests are simple, but mastery grinding can take time. This is where consistent farming becomes important.
Rimuru is easily one of the strongest specs in the current update. The moveset is fast, powerful, and works well in both farming and combat situations. While the grind can take time—especially with Slime Orbs and race RNG—the payoff is worth it if you want a top-tier build.
This update adds more than just a new character. With new systems like races, raids, and artifacts, Lineage Piece continues to expand its progression depth. Rimuru sits right at the center of this update, offering both a challenge and a strong reward.
If you focus on farming efficiently and follow the right steps, unlocking Rimuru becomes much more manageable. From there, it’s all about mastering the spec and making the most out of its powerful abilities.
