The Pied Piper of Hamelin

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

Cue / pattern
The Piper summons diseased rats.
Use area damage to remove the adds without giving up all pressure on the Piper.
Rats accumulate across turns.
Do not let multiple summon waves remain alive; their combined action count is the real enrage condition.

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.
