Anyone know all of the Constant Active Effect perks you get for doing quests? Like the "Ancient Knowledge" ability you get from "Unfathomable Depths" (http://elderscrolls.wikia.com/wiki/Unfathomable_Depths) or the "Sinderion's Serendipity" (http://elderscrolls.wikia.com/wiki/Sinderion%27s_Serendipity) you get from "A Return To Your Roots", or the "Sailor's Repose" (http://elderscrolls.wikia.com/wiki/Sailor%27s_Repose) ability you can get?

There's also Agent of Dibella and Agent of Mara.
When you meet Paathurnax, you can chose between Force Without Effort, Eternal Spirit (bugged) and one that increases Fire Breath by 25%. Forgot the name of the last.

There's also:

Archmage's Authority
Assassin's Aegis
Dragon Infusion
Gift of the Gab
Nightingale's Aegis

those with the ones already mentioned are all of the possible quest reward perks.

Here's a list of all the Constant Active "Perks" i've learned of, their effects, and how you get them.

none of this is shown as active effects at all even if you do all the quests needed. so this are not really permanent buffs. they are false or "hidden" values. tested nightingale and assassins. these both effects dont exist you dont get any bonus at all.

the only ones i know that actually SHOW in active effects are :

ancient knowlegde
agent of mara
agent of dibella
sailors [censored] (forgot name).
sinderions serpendy.
and the one effect from grey beard leader.

thats all that are there really. mara and ancient knowlegde are by far the best ones. knowlegdes discription is wrong currently. it infact increases ALL armor by 25% permanetly (values raise even when no armor is equipped wen getting the buff) and it lets you imporve all your items 15% more instead of making smthing level faster.
