How to mod perks using Creation Kit?

[Tilarta]

I want to modify two of the Fallout 4 perks to change their functionality.

 

The first is Animal Friend 1, I want to change it to an "always on passive", like it was in Fallout New Vegas.

Basically, I want it to make any nearby animals passive.

 

The second one is Nuclear Physicist 3.

I want to remove the explosive fusion core ejection and replace it with a function that makes fusion cores drain 0 energy, so the suit isn't draining energy from the core while it is in the power armor.

 

Another goal I have no idea how to add is to give the same functionality to the fusion cores that power the Gatling lasers.

Preferably as part of the modified perk above.

 

Essentially what I am attempting to do is have neverending power cores, regardless of whatever device they are slotted into.

 

 

Does anyone know how I can make the modifications listed above?

 

The priority is to modify Animal Friend 1 first, as I dislike being attacked by harmless animals all the time.

No, I don't want to kill them.

And I want this Perk modded before the release of Far Harbor (DLC) in two weeks.
