Description&Introduction
This mod adds weapon buff spell(Lesser Power) and shout allow you to buff unenchanted melee weapon with animation, can't buff on bow or crossbow.
Each weapon buff has special skill(weapon art).

00:14 - 00:31 Buff animation and visual effect showcase
00:35 - 00:40 Can buff when dual wield
00:41 - 00:49 Buff enchantment effect
01:00 - 01:18 Can directly buff on 2 handed weapon, don't need colorful magic + CGO
01:20 - 01:32 can't buff on ranged weapon
01:34 - 01:47 Alternative sound fx

For now release "Lightning Weapon" , "Blessed Weapon" and "Dark weapon" buff.
Not release frost and fire weapon buff because those visual effects made by me is for straight sword only, other weapons type are not match.
My buff visual effect is for maximum weapon shape compatibility.To keep your weapon type diversity(e.g.animated armoury) and less damage to weapon modder passion.
I don't want people chose his weapon base on visual effect.

How to get
Use "AddItemMenu" to get the spell tomes
Or use console "player.additem XX002718 1" "player.additem XX010e09 1" "player.additem XX011216 1"
(XX must be replaced with the number of my mod has in your load order)
Now you can use blacksmith forge to craft "Covetous Gold Serpent Ring".(Required 3000 gold & spell tomes: spark & healing & soul trap)
The crafting recipe won't show up if your inventory don't have "spell tome: soul trap".
When you equip the ring you can get all weapon buff spell tomes 
(Version 2.22) Added spell tome "[Weapon buff] Special skill".
(Version 3.0) Added item "Charcoal Pine Resin", Equip fire breath shout to use this item. After you see a fire weapon buff icon on your head, a new shout "Dragonborn Flame Arc" will added after 2 seconds in game(not in menu).

How to use
After you get the spell,you need to draw your unenchanted weapon before you select/equip the spell.
After you set those spells to hotkey you don't need to draw your weapon to select/equip again.
Spells cannot use when you using enchanted weapon or bow/crossbow.

How to use special skill

Two way to use special skill

1.
You can use blacksmith forge to craft "Darkmoon ring".(Required 10 falmer ears)
The crafting recipe won't show up if your inventory don't have 10 falmer ears

Equip item "Darkmoon ring"
When using weapon buff,perform backward power attack to use special skill.

You can use blacksmith forge to upgrade "Darkmoon ring"
"Darkmoon ring +1" +50% skill damage
"Darkmoon ring +2" +100% skill damage
"Darkmoon ring +3" +100% skill damage.Skill are 0.33% more powerful per level of Enchanting


2.
To use lesser power "[Weapon buff] Special skill" or MCM Special skill hotkey,require user equip "Farron ring"
You can use blacksmith forge to exchange "Darkmoon ring" to "Farron ring"
If you want to upgrade "Farron ring",you can exchange back to "Darkmoon ring" and upgrade it.After upgrade,Exchange to "Farron ring" again.


Do not equip "Farron ring" and "Darkmoon ring" at the same time.The skill damage won't increase more.
It won't break your game but it will make your game load unnecessary script.
(Both ring use Slot61,somehow it can stack with other item using slot61)

Notification for equip weapon buff spell
Consume the food item named "[weapon buff] Active notification" to active notification when you equip my weapon buff spells.
(new) version 4.6: You can toggle this in MCM now 

I am using soul quick menu but I dont like my power/shout slot over than 4 skill so i made this notification use with Serio's Cycle Hotkeys.
Serio's Cycle Hotkeys is SSE mod,but I think it is safe to port back to LE.
You may need too resave the ESP in Creation kit(LE) or merge with oldrim empty ESP plugin(load after) to change the form version.
I uploaded empty NIF for replace the icons of notification in case if you don't need the notification icons.

0:00 - 2:07 Notification and special skill showcase
2:47 - 3:10 Dark weapon skill combat test
3:11 - 3:33 Blessed weapon skill combat test
3:34 - 4:20 Lightning weapon skill combat test


MCM menu 

Set your dodge key in "Toggle dodge cancel special skill".It should be compatible with any dodge mod.

Highly recommend  Individualized Shout Cooldowns  use with "Dragonborn flame arc"

Recommend Warrior Magic use with "[Weapon buff] Special skill" (Version 3.2021 added MCM hotkey)You don't need a auto cast mod for "[Weapon buff] Special skill" lesser power now

Upgrade
(new) Overwrite previous version files if upgrade 4.4 to 4.6, Reactive the MCM option feature(Toggle on->off->on) if you are using food items feature in previous version
Deleted previous version files if upgrade 4.27 to 4.6 (I updated behavior file)
Delete previous version(4.1AMR or lower version) files if upgrade to 4.6 ,don't load a save that your character applying weapon buff on weapon.It may more safer to load a save without equipping darkmoon ring


Delete previous version files if upgrade 2.22v~2.6v to 4.6
Remove notification and active notification again if using notification feature
Re-equip the darkmoon ring or farron ring to check the "fire weapon art" has been added.
if not,use blacksmith forge to exchange farron ring/darkmoon ring and exchange back to darkmoon ring/farron ring
Equip the exchanged ring you should see the "fire weapon art" has been added
(The ring script will update when you get a "new" ring,Use "Additemmenu" get a new ring after drop your current ring will update the script too)
And of course, you don't need to do this if you start a new game or did not install this mod before.

Remember download the newest Skyrim Immersive Creatures patch for 4.46
if you keep using old patch the new effect of blessed weapon won't work.

Uninstallation

4. Save & Exit
5. Delete my files in your mod manager.


All of my script in this mod is activemagiceffect script.Script won't use if you don't use my spells and items.
(Version 3.2021) Added constant scripts for MCM

Compatibility
- Combat Gameplay Overhaul
when equip farron ring,can't use special skill if using CGO when equip 2h weapon.
Darkmoon ring is useless if using CGO

- SkySA
Can't use backward power attack when using SkySA,so the darkmoon is useless.Equip farron ring to use special skill(lesser power or MCM hotkey)

Known issues
1.After buff a weapon and change to other unenchanted weapon.The buff will gone,but the buff visual effectswill stay.

This bug is left by bethesda,vanilla shout "Elemental fury" already has this bug.
The worst way solve this bug is buff your weapon again and sheathe it.
The best way solve/avoid this bug:
Set your next weapon to enchanted weapon,you will never meet this bug again.

There have an imperfect solution for this bug.(Active "switch weapon bug fix" in MCM)
This solution won't work if changing multiple(>2) unenchanted weapon or changing weapon too fast.
Recommend weapon cycle set for this solution:
unenchanted melee weapon -> unenchanted ranged weapon
unenchanted weapon -> enchanted ranged weapon(include staff) -> unenchanted weapon

2.Weapon buff enchantment is permanently on my weapon

The legendary "Permanent Elemental Fury" bug,Thanks Bethesda.
This bug will happen if you load a saved game that your character is buffing weapon and unequip(switch or drop) your buffing weapon.
You only can abandon your weapon and get a new weapon if you get this bug
Or delete the enchantment by using "General Stores" "Legacy of the Dragonborn safe house"
No solution for this bug,yet.

But You can easily avoid this bug:

Try not to save your game when buffing weapon.
Just sheathe your weapon before you save game if you are using weapon buff
if you load a saved game your weapon is buffing,sheathe your current weapon immediately,don't change or drop your weapon.You won't get this bug if the weapon buff still remaining and cancel the buff by sheathe your weapon or buff duration run out.

(Version 3.2021 or higher)
There have an solution\avoidance for this bug.(Active "Avoidance of permanent enchantment bug" in MCM)
So you don't need to sheath your weapon when save your game to avoid this bug anymore.

3.Player don't use special skill sometime when equipping "darkmoon ring" and perform backward power attack

If you keep pressing left or right direction key("A" "D") before press back direction key ("S") to perform backward power,special skill will fail to use.
So if you want to use special skill,try to press "S" only when perform backward power attack.

Fixed in 4.25 version

Tips
1.If using [Weapon buff] Special skill with Warrior Magic,You can use special skill after timed block
2.If using tk dodge,you can back dodge and keep pressing vanilla block key to active special skill when using darkmoon ring.
3.To active Soul Drain effect,you can equip [soul trap enchantment weapon(left hand)] and use "dark weapon" buff your [unenchanted weapon(right hand)] when dual wielding,if using Summermyst you can make double weapon enchantment(soul trap + poison\disease) for more lingering damage,
