Temple noob. Why can't I place a spymaster next to the garrison in my chain?

The commander changes the garrison into something different and it’s not something that the spy master can connect too. It has to be placed on a regular lvl 1 garrison with no commander near it.

I don't care if I am getting downvoted, but for casuals like me and OP, trying to build temples on your own with in game instructions is just so punishing. No undo, tiles dependencies aren't explained beyond surface level text, and medallion tiles don't have the path display before you put them down.

I reset my temple for this exact problem. Where DOES it say when you connect your Commander tile in a chain, ANY subsequent Garrison no matter how deep in the chain and padded by Armoury it CAN NEVER BE connected to Spymaster?

Try google it will tell you - Commander

because there is a commander in the snake... did you watch or read any guide before starting this snake? theres no spymasters which means youll never have enough locks to keep your snake safe from destabilization

The Spymaster can't be placed next to the Garrison because it's treated as a Connections room, and those have specific adjacency rules for balance. You need at least one non connections room between them, so try putting a regular combat or utility room in between
