Description
All unequipped skills will be active as if they are equipped, except:

• Unequipped red skills do NOT boost adrenaline gain.

• Unequipped blue skills do NOT accelerate stamina recovery.

• Unequipped green skills do NOT prolong potion duration.

The following skills still need to be equipped to take effect:

• Aard Sweep

• Firestream

• Magic Trap

• Active Shield

• Puppet

• Gorged on Power

• Battle Frenzy

The differences with Active Perks and like:

• This mod does NOT allow unequipped skills to provide their shared secondary effects.

• This mod does NOT cause passive skills to apply twice if they are equipped.

• This mod does NOT highlight unequipped skills, but they will actually function.

Using on an old save
If you don't follow these instructions, you might end up with some - if not all - of your skill passive effects to get applied twice.
How to apply to an old save (ignore this step if you are starting a new playthrough):

• Before you install this mod, load your old save.

• Drink a bottle of "Potion of Clearance", then save & quit the game. You can gain one by console command "additem('Clearing Potion',1)".

• Install this mod.

How to remove from an old save:

• Before you uninstall this mod, load your old save.

• Drink a bottle of "Potion of Clearance", then save & quit the game.

How can I be sure if it's functioning?
Strong Back test:

• Be sure you haven't learned Strong Back yet.

• Learn Strong Back and you will see your capacity to immediately increase by 60.

• You can be sure that equipping and unequipping the skill doesn't affect your capacity.

Active Shield test

• Check your stamina regen speed by pressing C on inventory view.

• Equip "Active Shield" and cast it. You see Geralt maintains an active shield for as long as you press Q.

• Redo step 1; you can be sure your stamina regen speed has increased.

• Unequip "Active Shield" and cast it. You see Geralt casted the original sign effect rather than the active shield.

• Redo step 1; you can be sure your stamina regen speed has reverted back.

Igni Intensity test

• Be sure you haven't learned Igni Intensity yet.

• Check your Igni intensity and stamina regen speed by pressing C on inventory view.

• Learn Igni Intensity.

• Redo step 2; you can be sure your Igni intensity has increased, but your stamina regen speed has not.

• Equip Igni Intensity.

• Redo step 2; you can be sure your stamina regen speed has increased as well.

• Unequip Igni Intensity.

• Redo step 2; you can be sure your stamina regen speed has reverted back, but your Igni intensity has not.
