An empowered spellshard is keyed to a specific spell of up to 3rd level. When youcast the attuned spell, you can use your empowered spellshard as a focus in addition to the spell’s normal components (if any).Doing this empowers the spell (as though using the Empower Spell feat, but with no adjustment to spell level or casting time).

Bracers of arcane freedom allow you to cast arcane spells without the normal complex gestures required. When you activate
these bracers, you omit the somatic component of the next arcane spell you cast before the end of your turn (as if applying the Still Spell feat to it, but without altering the spell’s level or casting time).
