How do "Passive Skills" exactly gain XP ?

[Weiff]

Hello Guys !

I just started the game and its fking Awesome so far !
My question would be:
The Passive Skills for example "Whirlwind" how does it earn XP ?
Do you have to use it and damage enemys ?
Do you have to *kill* enemys with this exact spell ?
Or does it gains "passive" XP while ur killing enemys doesnt matter which ability you use to kill them ?

Hope this is somehow understandable ;D

Much fun & good loot for all of ya out there !!

You gain passive points when you level up or completing certain quests.

As for skill specialization exp bar, gaining XP in general, most notably upon killing mobs, will progress the bar.

Pretty sure it does not matter what skill you use to give them experience they just passive level as you kill stuff as long as they are selected as a specialization skill.

As you gain experience, your skills level up.

So later in the game, where you get more experience, your skills level up extremely fast.

This allows you to experiment a lot in a short amount of time.

(These are called "active skills", or just "skills", not "passive skills" by the way)

You don't have to have them in your skill bar for them to level btw.
Every specialized skill automatically gets XP when you gain XP.
