Temple

Do i need to lock a room every run?
Is there any guide out there, possibly written?

Are u looking for "snake" guides?

Not sure about written, but u can search "Milkybk" on youtube, he made a few explanation videos about building the temple. I'm sure there's others aswell.

there are at least six, and possibly even more content providers producing guides on youtube on the temple.

it's pretty much impossible to miss it when a person does a search on youtube.

It's not about building the temple but things like medallion rooms do not show connections until placed so you could loop the temple.

Another guy said vault room doesnt destabilize if dont enter main room but it's not true, mine said room complete without pulling levers and got destroyed.

just a need a guide for such details

not sure about the second point.

the first point can be mitigated by building your temple in the simulator and do a pre-test before you proceed with the real thing. this suxs and i agree ggg could do better by making the medallion rooms to show connections so that players will not accidentally loop the temple.

Vault rooms are like any other room if u don't pull the levers. They can destabilize, but it's not guaranteed.
If u open the vault tho, it will 100% get deleted.

For medallions u can read the wiki about what rooms connect or, like stkmro said, use https://sulozor.github.io/ for planning and putting down the room before applying the medallion.
It's unfortunate that GGG didn't implement it better, but I don't think it'll change until 0.5, so we have to deal with it.
