How to Get Solemn Lament in Lineage Piece (Butterfly Grave)
The Weapon
Solemn Lament (Mythical) — the twin-gun mourning kit from the Limbus Company crossover update, currently the top raw-damage unlock in the game (tier list).
The Dungeon: The Butterfly Grave
Get the key from the Angela NPC, then: kill 100 enemies to unlock phases 2 and 3 of Yi Sang (1.6B HP — the biggest boss HP pool in the game). Drops: Monochrome Wood 7%, Invert Tears 5%, The Final Elegy title 3%, Solemn’s Outfit 2%. The update also added Butterflyed mob mutations and Soulweaver Butterfly drops.
The Bill (Solemn Lament NPC)
- 1 Grief for the Dead
- 1 Lament for the Living
- 5 Fusion Cores
- 100 Soulweaver Butterflies
- 250 Boss’s Souls — 1 per Legend’s Arena boss kill, so 250 arena kills minimum
- 30M coins & 45K gems — the most expensive purchase in the game
Farm Plan
The 250 Boss’s Souls double as Trial Key currency, so your artifact farm and Solemn farm share a lane. Raiden’s endgame mastery (“deal 3.5B with Solemn Lament”) assumes you finish this — it is the final boss of the game’s economy, budget accordingly.

How do I get Solemn Lament?
Solemn Lament NPC on Frostborn Island: 1 Grief for the Dead, 1 Lament for the Living, 5 Fusion Cores, 100 Soulweaver Butterflies, 250 Boss's Souls, 30M coins and 45,000 gems. Grief and Lament are crafted at the Butterfly Shop from the three White / Black Gun Parts; Fusion Core costs 20 Boss's Souls + 100 Soulweaver Butterflies each.
How many Soulweaver Butterflies do I need in total?
100 for the NPC + 500 for the five Fusion Cores = 600 for the weapon, plus 35 per Butterfly Grave Key and 500 more for A Large Coffin if you go for the mastery — over 1,100 all in. The board does not list where the butterflies drop (see Butterflyed mobs).
What is the Solemn Lament mastery?
Deal 3.5B damage with Solemn Lament, kill 50 NPCs and 15 bosses that have the Butterflyed mutation, defeat the Solemn Lament User (Hard/Extreme) 15 times, and "bury the grief" — which requires A Large Coffin (6 Invert Tears + 10 Monochrome Wood + 500 Soulweaver Butterflies at the Butterfly Shop).
How do I get into the Butterfly Grave?
Butterfly Grave Key: 35 Soulweaver Butterflies at the Butterfly Shop (the update card says the key comes from the Angela NPC). Inside, kill 100 enemies to reach phases 2 and 3; Yi Sang (1.6B HP) drops Invert Tears 5%, Monochrome Wood 7%, Solemn's Outfit 2%, The Final Elegy title 3%.
