The Halo Wikipedia states that the San'shyuum didn't have access to the Anodynes Spirits weaponry, using weapons that they've build themselves powered by the ships core instead to eradicate Sangheili colonies during the War of Beginnings. These weapons would later be dismounted during the Covenants creation.

How powerful were these San'shyuum weapons?, how dangerous would they've been if they didn't make use of the Anodyne Spirits power output but rather let's say that of a CCS, CAS or CSO? Did the Covenant (loyalists) re-equip the Anodyne Spirit with these weapons before it made it's way to Earth (and the Ark)? What amount of damage could a plasma lance powered by the Anodyne Spirit inflict against other Covenant ships or a colony world?
