Nice, what companions are best? I usually have Brint and either Arona or Quin. Also, what are you recommendations on armor?
I like running Ryn in her healing set + Kiyoko. Kiyoko's default power suite synergies fairly well too. Blessed + Greases Crit Fireballs are fun. However, you're gonna be SUPER glass cannony. You might want to have Inspiration if you go up against a gang of Cultists and there's two Temptresses. If you want to go for a Resolve focus team, switch out your powers and give the Champ Greater Heal and try Atuiga and Quin or Atuiga and Azzy. Or Quin and Azzy if you're feeling bold. Honey Maiden Azzy is still stronk, even after the sexiness nerf.
Kiyoko's Kami-no-Michi is pretty damn useful too, and one of them makes her more tanky. With Mirror Stance and Karmic Retribution, you can do a good bit of damage from the enemies own attacks. Actually, all of Kiyoko's sets are useful, give them a spin.
Jotuns are freaking tough, don't worry if you feel like you HAVE to run. No shame in leaving a battle that isn't to your advantage.
As for armor, Dueling Hat/Everblossom Hood, Cloak of Winter, Apprentice Robes, Senninbari, Royal Gloves and Leather boots (lol). Mare's Ring and Lucky Strike for rings. I'm not a super optimizer.
