My Namahage is already at +7.
I have Boomer(at 1-1, currently levelling Ameonna) but I don’t have Gretel or Grimm.
I have Azlar(who I don’t intend to emblem) at 1-1 but I don’t have any other 5* Barbarian(or Azlar Costume).
My Gormek is currently at +7 as well.
Have enough emblems to take him to +20 in my inventory.
Of course if I do it I will go DEF>HP>ATK. I won’t force an elephant to fight like a tiger.
He seems to be one of the heroes that do get a bit from the 20th node. (Aware it’s not as good as Sonya’s 20th node but it’s something.)
