Just a note, so you can be all informed of this.
Custom craftables (key rings, mobile forge, toolhouses) say they are around 30-50% chance, but that information is false. I'm posting this until i fix the display on your chance. If i ever get to that.
Crafting all keys is a 12.5% chance.
Crafting the mobile forge is also 12.5% chance.
Crafting toolhouse and runichouse is a 41% chance.

I apologize for the missinformation. What appeared to be a 0.5*0.5*0.5 chance, is actually 0.5 chance of crafting it.
Here are a few results from actual testing with 120 in every skill. 20 attempts on each item:
Mobile forge: 12/20 (60%)
Tool house: 15/20 (75%)
Runic house: 12/20 (60%)
Stone worker's key: 1st try 12/20 (60%), 2nd try 14/20 (70%)
Metal worker's key: 9/20 (45%)

Crafters are welcome to post their results, about how many attempts gave how many of the keys or houses.
