Key Crest

A Key Crest is a work of dwarven technology designed for use with an Exsphere. When used correctly, the Key Crest inhibits the negative effects of the Exsphere. It is made of a special inhibitor ore, which can only be processed by a dwarf. Usually, the Key Crest acts as a mount for the Exsphere, but an accessory made of inhibitor ore with the correct charm carved into it will suffice.
