Where the block sits
Prison Block is the cathedral-side stretch with the large gear and the red window, not a separate overworld. Explore the Church uses “escape the prison” as its first chapter. A Steam thread about the Depths node mentions players getting stuck in the red-window room on a block puzzle. That is a player report, not a solved map, so this page does not invent the block order.
The plinth that got easier
Wayfinder Plinths are timed challenges. One of them, in the Prison Block, was harsh enough that patch 1.0.0.64 nerfed it. The note does not publish the old or new time. If you are on 1.0.0.65, you are on the nerfed timer. Dying to the old time and refusing to retry is the actual stuck state.
A complete step list for the block is not in a developer post or in two agreeing guides that I could verify. When that changes, this page will add the steps behind the usual fold. Until then, use the church chain for the exit goal, and use the plinth page under collectibles for how those timers are judged.
Questions this page answers
Why is the Prison Block plinth so strict?
It was. Patch 1.0.0.64 nerfed that timer. On 1.0.0.65 you are playing the easier version. The exact second count was not published.
