Legacy of the Last War
Mined only in Thrane, flamedtouched iron is rare and considered sacred by the Church of the Silver Flame. When mined, this iron variety has a speckled dark red color, resembling rust. Adherents of the Church of the Silver Flame believe that flametouched iron carries the particular blessing of their deity, and they use it to make holy symbols, weapons, and armor. Items not normally made mainly of metal cannot be made from flametouched iron.
A holy symbol made of flametouched iron increases the spell save DC of its wielder by 1 when he or she uses their Channel Divinity to turn undead. Weapons made of flametouched iron are considered to be magical (but do not have any other bonuses unless further enchanted) in terms of overcoming resistances against evil outsiders and undead. Creatures wearing flametouched iron armor have advantage on saving throws against spells cast by evil outsiders or undead.
A flametouched iron weapon or suit of armor has a market price modifier of +1,000 gp. A flametouched iron holy symbol costs 750 gp. Items without metal parts cannot be made from flametouched iron.
