Finishing Level 10?

[Shadowfied]

So I think I'm done in level 10.

I got a prison key which I have no idea where to use and I think I know where the stairs to level 11 is but there's a door which I have no idea how to open. What do I do?

[Devil]

Go and use the prison key? I'm assuming that door you can't open is a secret - if you want a hint check the spoiler

If its the iron door, you've used the item you need on this level already to open / close doors

[Shadowfied]

I don't know where to use the key. And it's not an iron door. In one room, there is a hole in the ground so you obviously can't get over, but there is a door, but no mechanism to open it.

[Devil]

Ah, I think i see.
Regarding the door - is it the one that you can see stairs behind it? - have you tried jumping?

Prison keyhole is downstairs

[Shadowfied]

Thanks. Got over that place now.

Where "downstairs" is it?

[Devil]

go explore, you will facepalm when you see just how easy it is to find....

[Shadowfied]

I've been searching. I honestly can't find it. I've been in the huge room with all the pits, put markers on the map and compared the location on each floor to try falling inside a room which is blocked off by a gate but no success...

Edit: Oh my god...I noticed those stairs near the crystal earlier, but since I had been there earlier I thought I had already checked that place. Geez...Indeed..*facepalm*....Thanks though man.

[Devil]

told you :p

also, you haven't checked all the pits if you didn't get in that room
