Broken Blade Bosses Guide
All bosses with spawn locations, respawn timers, key drops, and farm routes for Race, Element, and Blessing rerolls.
By Bloxron Editorial Team · Last updated
Overview
Broken Blade has 15+ bosses across normal islands, Niflheim, Nidavellir raids, Jotunheim, Midgard Island, Explosion Island, and Sky Spire. Farm Guts for Sacrifice Pieces (Dragon Slayer), push Sky Spire for Holy Grails (Excalibur), and use Headless Knight on Explosion Island for Eye Patches. Most bosses also drop money, EXP, ores, weapon pieces, and reroll items — target the encounter that matches your current bottleneck.

Raid Bosses at Nidavellir
Moraros, Magador, Ragaros, Velik, Nivaron, Gelaros, and Veyrath can all be summoned through the Demon Summoner NPC on Nidavellir Island. Raid tiers add:
- Moon Piece — crafting material for Moon Cut and related forge routes
- Boss Coins — exchange for boss rewards
- Element ores — Flame, Frost, Storm, Thunder at higher difficulties
- Runes — Souls Bomb, Hell Fire, Blizzard, Thunder, Shadow Clone (Nightmare)
Nightmare raids push Moon Piece rates toward 100% on several bosses. Only run Nightmare when your build clears it reliably.
