The stone itself is the visible change: a colossal, turning vortex rather than a static rock, its plating's own colour tracking how far the siege has fallen — a glance at it tells you roughly where the wall stands before the console does. Nothing about striking it changed underneath: the same daily cell, the same aim-then-swing rhythm, the same five hard-gated walls.
What did change is where a strike's force actually comes from. It used to be your claw's own tier; it's your weapon's now (see the next note below) — a strike's rank reads off whatever cannon or launcher is fitted in the new weapon slot, never the arm doing your hauling. The siege's own forge still builds three cannons straight from guardian-wave materials — the Arc Cannon at 8 Fracture Scale, the Maw Cannon at 10 Medusa Filament and 6 Gaunt Tooth, the Leviathan Lance at 8 Warden Plate and 12 Elite Carapace — the fastest, most earned route to exactly the parts the next wall is asking for.
