After merging with Byleth
DIVINE PULSE - Sothis' signature ability; one of the few things she still remembers how to do. Under normal circumstances, Divine Pulse allows her to reverse time with varying cooldown in-between. This power was primarily utilized to ensure the safety of Byleth's students, but as of late some mysterious unseen force has severely weakened it...
SOTHIS' SHIELD - A castable spell, Sothis can bless a person and temporarily increase their resistance to damage for a short time. This spell takes a fair bit of effort on her part, and as such can only be reasonably cast once per battle.
DIVINE LEVITATION - As one would expect from a Goddess, Sothis has a penchant for levitating off the ground.
