Spinebreaker’s follow-up
The Catacombs trainer checks M1 combat, blocks and your armor breaking. His trial asks you to clear five different boss rooms while using Bones, then bring a Torn Kaguya Arm. Exact minimum counters are not established by this Trello card.
Acquisition
The Halloween guide obtains a Curious Bone for 1,000 Candies at the Celestial Gate. It is account-bound, survives wipes, and wipes the character when used to change the bloodline. Current event stock is not established.
Spinebreaker prerequisites
| Counter | Video target |
|---|---|
| M1 hits | Approximately 2,500 |
| Blocks | Approximately 1,000 |
| Your armor broken | At least 25 times |
Two clan quests
- From Windy Plains 1, enter The Catacombs, turn right and find the hidden gate opposite the button. Speak to the Spinebreaker.
- Once eligible, accept the first quest and defeat five bosses in boss rooms. Mission and global-event bosses do not count.
- Return, finish the quest and accept the second: hand in a torn Kaguya arm, obtained with a Scalpel. Your own Kaguya arm can satisfy it.
- Complete the hand-in to finish the clan progression.
Unlocks
Bones is available at spawn; Bone Manipulation is the progressed awakening. The latter adds Drilling Bones, Fern Dance and Willow Dance.
