Spellsong is a form of power that allow its user to manipulate elements of the Aurbis by producing special sounds in a certain order similar to the Thu'um, Sword-Singing and Green Singing. Given that it is established in the Elder Scrolls universe that sounds in the proper arrangement have power, it is crime that bards haven’t received any special powers. These abilities are unlocked by raising your bard skill level by playing your instrument and you make the song tomes at the scriptorium at the Bards College. These songs almost all affect your character and your allies. Rather than magika, using the Spellsongs is based on stamina.
