Infinity Castle Tactical Breakdown
The Infinity Castle functions as a shifting labyrinth designed to isolate Hashiras and force split-second choices under extreme pressure.
Navigation relies on scent, spatial awareness, and synchronized team maneuvers, with the structure itself acting as both fortress and executioner.
Demons within exploit psychological triggers, turning corridors into hunting grounds where fear becomes another weapon.
Support units relay real-time intel, allowing Tanjiro and senior Hashiras to coordinate ambushes despite the maze-like chaos.

Strategic Combat Rules
Within Infinity Castle, every encounter follows a brutal set of implicit rules that determine survival.

Regeneration limits create narrow windows for finishing blows, emphasizing precision over prolonged confrontation.
Surviving the Next Infinity Scale Threat
