>TS: Try using an apple with the alchemiter.
It's experimenting time! It looks like Applejack and Rainbow Dash are already trying to figure out what you just deployed next to them by, uh, standing on top of it, but your studies of "Lodestar" give you an advantage. If you recall correctly, the alchemiter is used with CRUXITE DOWELS to alchemize things, but what if you tried placing something on that little reception pillar that isn't a cruxite dowel? Surely Applejack won't mind if you pick one little apple for the sake of experimentation. Careful, now, careful...
Buy some apples!
...is what you're going to have to do now to make this up to her, you bet.
