Lighthouse Maintenance Detonation Fuses

The crude detonation fuses become vital tools in the Doctor's hasty pivot from defensive combat to offensive weaponization. Though not used directly in this event, their mention establishes the team's material constraints and desperate improvisation culture.

Skinsale provides frayed fuses to the Doctor, who immediately ignites one to detonate gunpowder on the stairs, creating a smokescreen to impede the Rutan’s advance. The fuses serve as the critical ignition link in a desperate and improvised defense strategy.

The Doctor urgently demands and receives a fuse from Skinsale, lighting it with a match to ignite gunpowder on the stairs. This creates a massive flash that disables the Rutan scout temporarily, demonstrating the tactical use of improvised weaponry in the confined space of the lighthouse staircase.

The crude detonation fuses bridge the carbon arc circuit through the extracted diamonds, channeling the lighthouse's power into an improvised weapon. This engineering marvel turns the lighthouse and its lamp into a deadly trap against the Rutan scout.
