Of your other unleveled 3*s, I have fully leveled, limit-broken and emblemed Chochin, Helo, Nashgar, and Dölgöön. Helo is great; Dölgöön is quite useful; Chochin is good; and Nashgar is disappointing.
You already have Namahage leveled up: in practice, Nashgar is like a lesser version of Namahage. But you’ll eventually level him up just by feeding him future Nashgars, so he’s worth keeping.
Dölgöön’s 2x mana skill is terrific. He also gets really beefy when fully maxed.
(HP max emblem path: his skill doesn’t depend on his own stats so I just wanted maximum survivability)
Unfortunately, on defense (that is, when run by the AI) only his 1x mana skill fires.
I am using Sudri a lot even though he’s not yet fully leveled. Agree w previous votes for him.
Whacker, Bauchan, and Vodnik are worth leveling up 2 or more copies. Probably Shrubbear, too, idk.
The good thing about deciding not to level up a specific 3* is that from then on, all future copies become juicy food
Your leveled 3*s include some of my favorites: Maeve, Jarvur, and Nordri.
FWIW, I have yet to see the point of Renfeld, Schlitzer (whatever he is in English!), or Jahangir. But that’s just based on their (in)effectiveness on defense teams I face. Presumably your results differ.
I’m so envious you have Garjammal! Regardless of her usefulness, I think she’s super cool
