Not Talents but next best thing:
Best defensive worn items I've found against Afflictions (ESPECIALLY for solo runs):
Company Captain's Cap [Head slot]: Immunity to Confuse, Daze, Charm, and Dominate. Passive
Steadfast [Weapon slot]: Immunity to Frightened and Terrified. Passive
Ilfan Byrngar's Solace [Weapon slot]: +50 Defenses while Stunned
+50 Defenses while Prone. Passive
Solitary (from Comtessa's Gage [Hands]): Immunity to Paralysed. If you are soloing and don't have any summons, this appears to be effectively passive.
Clarity (from Looped Rope [Waist]): +20 Defenses against Blinded, Charmed, Confused, Dazed, Distracted, Dominated, Frightened, Hobbled, Paralyzed, Petrified, Prone, Sickened, Stuck, Stunned, Terrified, Unconscious, Weakened attacks. Passive
All of these items except the Looped Rope provide other benefits, some very substantial!
Limited time:
Ring of Unshackling: 5 seconds of Suppress Affiction. Might be just the thing to allow you to get up other defenses. Can go for longer in combo with Spelltongue. Boeroer mentions this in another thread as can be ALMOST continuous with high enough weapon speed. (dual wielding?)
Scroll of Defense: +20 to ALL Defenses for 15 seconds (+ INT bonus). So you don't get Afficted in the first place!
Oops, just noticed that this was posted Feb 2017 not 2018. But I've taken the time to write it, so may as well post it!
