Here is a guarenteed list of what would happen with fusing:

1*(Gold) and 1*(Gold) = Anywhere from 1*(silver) to 3*

2* and 2* = Anywhere from 1*(Gold) to 4*

3* and 3* = Anywhere from 2* to 5*(extremely rare)

4* and 4* = Anywhere from 3* to 5*(More common and 3 and 3, but still extremely unlikely)

5* and 5* = Anywhere from 4* to 5*


 * From here on, it is based on personal experience***

Hope i help. With different rarity they both have to be the same level. So:

2* and 4* = The highest you can get is a 4*, because that is the highest possibility from a 2*

1* and 4* = The highest you can get is a 3*, because that is the highest possibility from a 3*

Hope this helps :D
