Secrets & Elru location

Chapter 1 — Bunnyville & the first descent

The tutorial chapter. You learn movement, basic attacks, blocking and the town loop.Don't skip town upgrades — the game doesn't tell you how important meta progression is until chapter 3 punishes you for ignoring it.

Chapter 2 — the tower opens

The tower's full layout unlocks: multiple floors, optional rooms, and your first real artifact choices. This is the chapter to start experimenting with artifact combos — see ourArtifacts Database for what combos well.

Chapter 3 — the first wall

The Chapter 3 boss is the community's most-quoted difficulty spike ("Chapter 3 end boss is hard" is a perennial Steam thread). If you're stuck:

Farm 2–3 meta upgrades (Max HP, healing) — this matters more than skill.
Bring a full potion stack into the fight.
Full pattern guide: Chapter 3 Boss Guide.

Chapter 4 — how to unlock it

Chapter 4 is the most-searched unlock ("sephiria walkthrough chapter 4"). Requirements:

Defeat the Chapter 3 boss.
Return to Bunnyville and speak with the story NPC marked with a !.
Complete one full tower run to any floor boss (the game tracks "tower progress" even on failed runs).
Speak to the NPC again — the path to Chapter 4 opens.

⚠️ If the NPC doesn't have a new dialogue option, you missed step 3 — a full floor-boss run is required, partial runs don't count.

Chapter 5 — preparation check

Difficulty jumps again. This is the chapter where build coherence becomes mandatory — random artifact stacks no longer cut it. Review our Best Builds before attempting the chapter 5 boss.

Chapter 6 — the final boss

The finale. Requirements before the fight:

A complete, coherent build (not random artifacts).
Full potion stack.
Knowledge of the final boss patterns — especially the last-20% survival phase.

Secrets & Elru location

"Sephiria Elru location" is a top related-search — Elru is a hidden NPC/collectible. Where to find them:

Elru appears on Chapter 4 floors 2–3 in a hidden room behind a cracked wall (destroy it with a charged attack).
Interacting with Elru unlocks a side quest chain that rewards a unique artifact set.
