Skyrim: Weapon Arts Scripts

How to make Weapon Arts that look like Bloodskal Blade?

Steps:

Create a new Magic Effect —> Create a new Spell —> Attach the Magic Efeect to this Spell. (Type:Ability;Self)
Create a new Perk —> Attach Perk to a weapon —> When weapon equips, the game gives the Perk to Player —> The Perk initiates another another Weapon Arts Spells to Player.
Create the actual Weapon Arts Spells. Just copy Vanilla Bloodskal Blade Spells.Make two of them, one is for Horizontal, another is Vertical. Those spells will shoot shoot Magic Waves when the effects start. When the Magic Waves hit NPC, they deal damage to them.

Two versions:

Lite version: Good for Two-haned Greatsword. The code is from the Vanilla game.
Complex version: Used for One-handed weapons and Two-handed Axes and more. Code is from @Azazellz.

Whenever the attack event happens, the game listen to Player’s animation types, and apply a magic effect to Player. There are two Properties:

SpellHoriz - Link it to DLC2BloodskalBladeSpellHoriz
