Does the stunned troop who has jinx as his trait, still keep the jinx on your gem masteries ??
I have tried gnome vaults, other battles. The jinx is still there even after stun.
Jinx falls into category of traits that activate and apply one time only with permanent effect in troop loading phase and therefore can not be stunned for practical purposes (others of the same type - X% mana start, Revered, Accursed, all Heart traits, all Bond traits, all Deep traits for delve troops from the top of my head).
