Favorite knowledge perk?

I love the knowledge perks, I hope we get them back in DA4

If I can I unlock all of them for the extra XP, but I only use those that I think that fit the character, and as I almost always a mage, my priority tends to be arcane knowledge. For my canon Inquisitor I sometimes use history knowledge too, since I imagine that she spends a lot of her free time in the library, so she probably learned a few things, but I don't like this one so much. I was curious about nobility knowledge and once I tried to use it more, reasoning that she knew nothing about that kind of stuff when she arrived but that in time she started understanding how things worked among nobles... but it didn't really fit her and I didn't like it much either, so never used it again (that I can remember). Underworld knowledge is something that fits better with some of my Inquisitors, so I have used it more often and I like it a lot. But yes, I definitely need to somehow make the options fit with my PC personality, one way or another.

All in all, my favourite is arcane knowledge hands down

Which one is this?

And I pick all of the knowledges, but Arcane is probably the one I find the most useful (Nobility comes in second).

Oh, her. You can just find a letter lying around saying she's a smuggler, so I've never needed that.

I love all of them (they are a must have for me) but Arcane Knowledge if my favorite, as it seems to be the most used of the dialogue perks.

I take all four of them as my first perks, and I pretty much use them whenever they're available.  Usually it's Underworld or Arcane first due to early War Table stuff, and getting Deft Hands unlocked ASAP next.

I agree that it makes sense for those backgrounds to have those particular perks. I suppose they decided not to do that to allow for a more customizable character - maybe your non-mage Trevelyan is obssessed with magic and never bothered socializing with their peers or reading a history book.

I guess that's how people like Dagna come about!

I guess I would say I got more use out of Arcane Knowledge. It comes pretty handy during the Well of Sorrows, where the Quiz figures out what exactly the price of taking it is. Also, during Solas's quest where the perk let you know how to destroy the binding's on Solas's friend.

I get all the perks because I feel that regardless of whoever you choose as an Inquisitor, they will be schooled, especially in nobility things. Don't want to send the Inquisitor to the Winter Palace without knowing a thing or two about the Game.

I also like Underworld Knowledge, even though it might not make sense for my Lavellans to have it, as it just makes them seem more craftier.

Dutches: "Do you even know who is friend and who is foe?"

Inquisitor: (Underworld perk) "If I have learned anything, your grace. It is to put my trust in no one."
