I have a lot of fun with Kvasir, and bring him on the world map a lot for farming (e.g. Atlantis Rising). Mine is +6, but his bulk and minions are excellent, and the fast speed killer. Sometimes I will play with a passive-only or DoT-only team, and Kvasir just makes it so much fun.
In a similar vein, I love using Valeria for farming because of her Very Fast speed and stackable DoT. For giggles, I did a Very-Fast only farming team (2x Valeria, Margaret, Malosi and Vlad) before dropping Vlad for Kvasir. Just totally destroyed the enemy mobs, and after murdering the middle I would just ghost tiles and charge with every 3-match. Fun!
I also have a lot of fun with my mono-Yellow squad, that includes Joon-costume, Inari and Malosi. Many times Inari’s dodge + Joon’s blind will make an enemy AoE attack miss completely. Won a raid last night where Vela and Zimkitha just completely missed me, then Malosi blocked Kunchen’s defense down…
Another fave farming / world map team is Kiril, Isarnia, Lepus, Jack O’Hare and Gregorion. attack buff, defense down, two hard-hitting Springvale heroes and a crit booster.
And of course, Proteus and Hansel especially against enemies that charge mana. Let’s me pop off-color diamonds with ease.
Seshat also often comes along when Proteus does. Her replicating minions allow her to tank serious hits, and she can snipe back - she’s been my last hero standing so many times.
Lastly, I am appreciating Elena more and more on Valhalla Hard stages AND on raids. I’ve watched many enemy snipers suicide on her riposte, and the Fighter talent is icing on the cake.
