Lightning Damage and fireballs

[WiebeHero]

So im WiebeHero and i have been working on custom enchants and so on so on and have been doing great so but i got 2 problems with lightning and fireballs here is the code i have now for them both.

on damage:
attacker is player
chance of 100%
if the 1st line of lore of attacker's held item contains "Paralyze I":
strike lightning at location of victim
apply slow 20 to victim for 5 seconds
loop 50 times:
play entity effect hurt at victim
wait 0.1 second

on rightclick:
player is holding a blaze rod
if the 1st line of lore of player's held item contains "Large Fireball I":
shoot a fireball from player

1. Lightning i want it so the attacker doesnt get damaged by the lightning as well
2. Fireball How to shoot a large fireball, how to get a cooldown for such a rightclick enchant and how i could change the damage that the fireball does (Increase)

If you guys could help me with this it would be great! Thanks!

to make the lightning not the damage attacker you can do this

strike lightning effect at the victim #doesnt damage anyone
damage victim by 5 #damage the victim by how ever much lightning does (idk off the top of my head)
