Find the computer room

Yesterday was not a very productive day for me. My computer decided it was going to freeze at random intervals for no reason throughout the day. I threw it into a volcano and it works now, but the lava deleted a bunch of data I had to fix. The good news is I implemented my gem forging system about 30% of the way, and I must say it's pretty cool for an RPG maker thing. The next step is finding a way so I DON'T have to program 2^50 conditional branches in order to implement it correctly. I'm sure there's some way.
