[Bruno]

To be clear, a character with this enhancement switches between modes depending on whether they're spending FP or not.

So if you have Duplication 10 (Multiplication) you can have 10 regular old Duplicates for no FP cost or when you are out of combat you can spend one FP per minute and get 100 Duplicates, to do out of combat things with.

This is also a very useful build for some kinds of super-speedsters.
