Boosters and the Mystic Forge

So if you can do that with exp booster, how about the others? Anyone know the recipe to karma and magic find? Or is it even possible to use those in the forge?

Doesn't this mean the others don't work?

Dammit, didn't see that one. Was too excited.

5 boosters + extra for the power of 4.. not worth it ='( and no karma booster
