Charmstones are obtained by freeing Gremlins, Cupids, and Gnomes with their associated spells from the Spirit tab of the Spell book (Break Curse, Cupid Calmer, and Revert to Reason spells, respectively). Each cast produces 3 Charmstones and 1 XP. Charmstones can be used for purchases in the Charmstone Market or to remove Blue Moss from objects in the areas of the Gremlin Village and Gnome Burrow.
