Untroubled by Darkness is one of those cards that really only works in specific quests, but in those quests is a powerhouse. Global willpower boosts are always good, but the restriction of Dwarves and the "restriction" of Dark/Underground relegates this one to the binder most of the time. Quite a good sideboard card along with Ever my Heart Rises and ally Bombur.
Untroubled by Darkness
Action: Each Dwarf character gets +1 until the end of the phase. (+2 instead if the active location is an Underground or Dark location.)
Khazad-dûm #10. Spirit.
With the help of this card me and my brother got at least 60 EXTRA progress on the last stage of the last scenario of Over Hill and Under Hill! In one round!!! Very good card especially for KD. This is a must have in DWARF decks
Over all 9/10
