Pied Piper of Elixir
BLACK SOULS · Early game

Hamelin's debt collector, re-armed with an elixir instead of a flute. Just under half of all players (49.6%) have put him down.
Where and when
The Pied Piper waits in Elixir's sewer and repeatedly calls diseased rats. Area damage prevents the summons from turning a straightforward boss into an unwinnable action-economy problem.
Location
Elixir sewer.
Prerequisites
- Reach the sewer route beneath Elixir.
- Defeat the Piper before Elma relocates through the sewer if preserving Elma's companion route.
Attack cues and responses
Loadout
- Reliable area damage
- Status recovery appropriate for diseased-rat effects
- Sustained damage for the Piper after each add clear
Rewards
- Pied Piper of Elixir achievement
- Safe sewer state for Elma's route
Route risks
- Leaving the Piper alive when Elma takes the sewer route causes Elma's death.
- The boss and Elma timeline should be verified on the same branch save.
First-hand verification backlog
Capture these in one documented Steam-version run before this page becomes indexable:
- Sewer entrance and boss position
- Rat summon wave
- Area-clear result
- Elma relocation with Piper alive versus defeated
Context and planning notes
The Piper marks the midpoint of the opening run — the last stretch where the game is still mostly teaching. Expect trickier patterns than the straight brawls before him.
The source tale is about a paid promise broken and children led away as the price. Keep it in mind: BLACK SOULS consistently makes its bosses' fairy-tale logic part of their fight and their tragedy.
If he walls you, the parallel bosses of this band (Knight in Armor, Hansel and Gretel) are usually reachable — rotate rather than grind.
