Lineage Piece Slime Orb: How to Get It & Summon Rimuru

What the Slime Orb Does

The Slime Orb is the summoning item for Rimuru, the 50M HP slime boss. Hand an orb to the Slime Summoner NPC and Rimuru will spawn in place of Sung Jin Woo on the next 90-second boss cycle. The orb is consumed per summon.

How to Get Orbs

• Hollow mobs (Lv.2000) — 1% drop.
• Arrancar mobs (Lv.3000) — 1% drop.
• Exchange — orbs can also be traded for at the slime-content NPCs.

Grind whichever of the two mobs your build clears faster; luck buffs raise the rate.

Why You Want Rimuru Kills

Rimuru’s drop table carries the whole slime chain:

• Slime — 35% (consume for the Slime race, 5% success per eat)
• Slime Essence — 15%
• Slime Core — 10%
• Shizu Mask — 1.25%
• Demon Lord title — 4%, plus Artifact 50%

The Rimuru melee needs: Slime race + 7 Slime Cores + 1 Shizu Mask + 10 Slime Essence + 5M coins & 10K gems. That is roughly a dozen-plus Rimuru kills on average — so stock several orbs before you start the session. Full slime-race numbers: races guide.
