About this mod

Most legendary effects can be detached from weapons and armor, then attached to different weapons and armor, with reasonable restrictions.

Permissions and credits
Legendary Swap
Most legendary effects can be detached from weapons and armor, then attached to different weapons and armor.
The detached miscmod items are named to reflect their restriction. They have a weight of 0.2 and a value of 100.

Some combinations of weapon and legendary effect don't function properly or at all, or don't make sense. I have added restrictions so that they can't be created.

Legendary effects that are normally found and only make sense on Ranged weapons are restricted to Ranged weapons.
Legendary effects that are normally found and only make sense on Melee and Unarmed weapons are restricted to Melee and Unarmed weapons.

The Explosive, Incendiary, and Plasma Infused legendary effects are restricted to Ballistic weapons.

Never Ending can't work with a Laser Musket, Syringer, Harpoon Gun, and Junk Jet so I made it so it can't be attached to them, as well as the Fat Man and Missile Launcher.
Never Ending is buggy on a Gatling Laser, but since Aeternus exists I allow it.

Unique legendary effects

The Automatic laser musket legendary effect is restricted to laser muskets. (unchanged from vanilla)
Atom's Judgement is restricted to Super Sledges. (unchanged from vanilla)

World Series Logo is restricted to Baseball Bats.
Shem Drowne's is restricted to Revolutionary Swords.
Lucky Eddy is restricted to Lever-action rifles.
Striker is restricted to Fat Man.
M4 Carbine is restricted to Combat Rifles.

No restriction has been added to armor and clothing.

Unremovable Legendary effects
The OMOD for the Lightning legendary effect of the Tesla rifle doesn't actually do anything, and the Tesla rifle doesn't have a legendary attachment point. This is unchanged from vanilla.

I similarly made other legendary effects unremovable.
The Salvaged Assaultron Head (OMOD only contains description and self rad damage.)
Grognak's Axe

The Smart Fragmentation Grenade (OMOD only contains description and keyword.)
The Fragmentation Grenade MIRV (only removed the legendary attachment point, it has no OMOD.)

Additional Features
Mr. Handy Buzz Blade has been given a legendary attachment point.

Still Allowed "Bad Combinations"
Instigating, Powerful, and Mighty don't work on a Missile Launcher.
Never Ending is buggy on a Gatling Laser.

Other Information
The plugin is an esl-flagged esp.

This mod is not compatible with other mods that share some of its features, such as:
- Legendary Modification
- VIS-G Legendary Modifications
- Alternative Legendary Modification
- Crafting Framework - Ammo . Armor . Junk . Legendary . Weapon / Equipment and Crafting Overhaul
Love to Craft - Legendary

Warning: If you want to switch from one of the mods above or any other that makes legendary effects detachable, you will lose all currently detached legendary effects. Uninstalling mods mid-playthrough is not a great idea anyway.

Contrary to these mods, mine doesn't allow the crafting of legendary effects, doesn't allow additional legendary slots, and is more (reasonably) restrictive with what effect can be attached to what weapon.

This mod is not compatible (without a patch) with mods that make changes to weapon records, because of the new keywords I added to weapons to implement the restrictions. 

It also means that weapons added by mods and creation club need a compatibility patch.

This mod doesn't add legendary attachment points to clothing items, if you want to be able to add a legendary effect to every clothes, you will need a mod that adds them. (for example, my mod Clothes Customization and Cleanliness)

Automatron, Far Harbor, Nuka World
UFO4P (its knife keyword and other changes are forwarded.)

My Other Mods
Clothes Customization and Cleanliness
Unzippable Vault Suit with CC Customization Integration
