I was thinking of adding a sub line requiring them to have heavy armor prof and tower shield prof or something similar as its intended that they are an extension of the character's ideals and not just random people following him.
No legendary is only require for it to be usable 1/week.
It may be inspired by new poppy.
Vauron I see plenty of options and as for characters, Elsa, Iceman, Killerfrost, The Snow Queen(of the orignial Fabel), Gray Fullbuster(Fairy Tail anime), Jack Frost, Lissandra(LOL), Jadis the White Witch, Kuzan(One Piece).
