I've been trying to get through a locked door at the academy level 3 where you're trying to beat Samuel to the exit. It's the one past the series of five levers. I read an earlier post that there's supposed to be a saphire key under a rock pile...but I've wandered around forever and can't find it. There's also another locked cell door with two locked chests that I can't open either. Does that have something to do with it? I'd appreciate any help!
If I remember correctly, the key is just northeast of where you first talk to the instructor. Not positive, but I remember a key there in one of the quests. Hope this helps.
Trilby, if you pass the corridor with the 5 levers, you're in a rather large room, right? And near the south entrance is a pile of rocks, bones etc => use ALT => the key is there.
2 locked chests => are a case for lockpick, sorry. Kiya
