Dazzling Mirror

The Dazzling Mirror is a Furniture item that provides the Mirror's Blessing damage buff that increases damage by 8% for every nearby player. It can be placed on the wall like all other types of furniture.

Like the Heart Lantern, the buff applies to players standing within its 50 tile radius providing a damage boost. The damage buffs with Wrath Potion buffs from both items will stack together to provide a greater damage boost.
