S1-E3 — Twelvefold Basin Alignment
Challenge 4: Twelvefold Basin Alignment
Primary CheckPerception DC 16 to identify the incoming mark; Thievery, Crafting, or Athletics DC 16 to set its basin.
The party works from opposite ledges while black water carries each mark from the Intake. Each round, identify the mark and set the matching basin-stones. Achieve 6 successes before 3 failures. A failure raises the water and brings the submerged guardian closer; entering the central pool triggers the threat immediately.
Critical SuccessThe final basins glow gray, the water drains toward Area 4, and the submerged threat withdraws unless already engaged.
SuccessThe matched basins glow and the flood recedes one step.
FailureThe water rises, footing becomes difficult, and the guardian moves closer to the surface. Count 1 failure.
Critical FailureThe basin cracks and the central pool erupts. Count 1 failure and trigger the submerged threat immediately.
