I have went into the CK and went to the spells section of the npc and I add a spell but the npc won't use them. What am I doing wrong can anybody tell me?

So is this a big issue that nobody can figure out or does nobody give a crap?

Hmm... I think your best bet would be to load up a vanilla NPC that you know can use shouts. Jarl Ulfric for example uses them. those undead lord things use them.

My guess is that there is more to making NPCs use shouts than just giving them the ability. There's probably a script attached to them that controls when to use which shouts.

So load up those NPCs and study everything about how they are set up, including the scripting that they may have associated with them.

I damn I feel dumb I didn't even think of that. Thanks for the reply I am going to go check that

I got it to work the shout works fine but the npc doesn't use any words. Well at least I can get them to use them

If I'm not mistaken, only the dragonborn and the greybeards have recorded shout words. You might have to record them yourself, but I'm not 100% sure on that one.

well how could use the dragonborn shout sounds one npcs?
