This suit of red dragon hide armour was made from the skin of Splatterblood, a wyrm who once crossed paths with the heros of the vale. After his defeat, Schallat gathered a section of his skin, and had it fashioned into a suit that we could hear.
Schallat considers this item to be holly, a sign of Chislev's favour. It's one of the finest pieces of armour available to a priest of his order. It also serves as a reminder that raw power alone is not always enough to triumph.
