Damn I thought that was the “Dwarf Jeweler” troop I had imagined in the “the trait troop” thread (no links provided, I’m on my phone, it’s a pain)
Same mana color, kingdom, troop type, rarity and quantity of mana required.
Sirrian even talked of traitstone’s origins up there so I was convinced it was it.
What a let down
Well, whatever, my Carnex won’t be displeased
EDIT : now I’m on computer so here is the link The trait troop - #5 by Zelarith
