Modding Help help to change the energy use of my weapon

I have a weapon with the ability "spearcharge" and I want to change the energy use and the distance of the dash but I don't know how to do it. somebody could help me?

 

"altAbility":{
"energyUsage" : 60 <---- change this to whatever you want
}

You can put the energyusage in the same section as the rotation stuff, dont make a new altAbility { } section
