Fallout 4 New Legendary Effects, help needed integrating.

[manbeerpig21]

In Fallout 4's creation kit, I have made some new legendary effects such as one I dubbed "Ruthless," giving whatever weapon 25% Damage and 25% Rate of Fire. I have made them in the GECK and am having trouble integrating them into the game so that weapons (and armor) that would be effected by these new legendary effects are dropped by enemies (i.e) a Ruthless Combat Rifle. Any help would be appreciated.
