Help with some lines of code, new to this whole thing

[Shinoryoshu]

So im making my first mod and I got everything done besides the last perk i'm going to give the character.  She powers up from getting hit by lightning much like Wx, but she gets a damage multiplier bonus instead of the light and run speed.  The problem is when i went digging into Wx's script looking for the code that runs that I couldn't pinpoint the line that i need to copy and modify to give her this bonus.  i was thinking it would be something like 

local function onlightingstrike(inst)

inst.components.combat.damagemultiplier + (value)

but of course I'm a noob when it comes to programming could some people help? I attached the LUA file for the character 

nora.lua

Take a look at this, I removed or disabled (with "--") all things but the attack multiplier and the talking. If you have questions, even stupid sounding ones, feel free to ask!
