I am getting close to opening Ravels gate, but I need the dodecahedron located in the closet of the Sensate hall in the Clerk Ward to move forward. I CANNOT for the life of me unlock this damn closet: I have bashed it and lockpicked it to death (Annah has a 100% lockpicking ability it says) and it will not open. Its infuriating because when I watch or read tutorials of this portion there is NO mention that I should have difficulty opening this door (am I forgetting something?). The game's story is at a stand-still til I figure this out, help someone please? ALSO I have tried switching the nameless one to a thief class and picking the lock with no luck, this door seems impenetrable.

Do you have any mods installed? It seems one of the fixpacks moved the Dodecahedron to a shelf and upped the difficulty of most of the locks for some reason.

I'm not entirely certain how locks work in this game, but as I recall, in other Infinity Engine games you only get a set amount of tries before the game decides you've "failed" at opening the container. For this reason, always save before trying to open a locked container. I think a change in your stats might cause the failure flag to reset, or maybe I'm thinking of another game?

Regardless, my advice is to reload an earlier save. If there is none, go pick up some DEX tattoos and stack as much Thieving (or whatever it's called) as you can from items, then try again. Analogously, buff your strongest Fighter with as much STR as you can, then use the crowbar to bash the container. You did save the crowbar, right? It gets a bonus to bashing locks.

Finally, if you have no mods installed you might want to try the fixpack in the stickies which, as mentioned, moves the Dodecahedron to a nearby shelf.

I hope this works out; there are a few scenarios where the game becomes unwinnable around here.

Spoilers here:

Have you completed and used the dream machine that was being built for you in the foundry? If you use the machine and complete the quest inside you will 'remember' how to open the container. I think I recall correctly that the container can only be opened if you know what it contains and through this dream you remember what it contains and then can go back and open it up! Hope that helps!
