Ruby Arcanum is required to cast this spell, granted from casting Aethercharge but only becoming available for use once the Trance Gauge is empty. Once Summon Ruby has been used, Fire Attunement grants casts of 
Ruby Ruin which can be used by casting Gemshine. Any remaining stacks of Fire Attunement will be lost if another elemental summon (like Summon Topaz) is used.
