does mediah, valencia, kamasylvia and driegnan quest line give inventory slot and how many?

They should all be here if any left

 

That's not true. The Black Spirit gives you inventory for various quests not listed in there as well.

 

Oh see thats why i said should and why i will say thank you cause i only knew about them being given in this enchanting start questline. Well i am a cheapass i would still do them for crystals and sell them like a bum xD
sad to admit i rolled few alts for the stones on 56 haha i should be ashamed of myself more xD

 

There's at least 7 -10 inventory slots in the questline "Lets see some skills". It's interwoven with the main black spirit questline and is also the questline needed to unlock the fairy. That's just one example, there are many more.

 

There are no inventory slots in the mediah,valencia or kama storyline, however there is 1 (maybe 2 i forget) in drieghan.

It could have been a side though, I do not recall exactly where I got it from. I would do some research because you need both kama 1 and 2 to do dreighan main storyline

 

Yes, there 1 quest in drieghan with inventory slots as reward. Here you can check the requirements for the quest, so you are able to do it
