Arcanum Master

With a wellspring of magic flowing from their veins and a divine understanding of all magic, the mystic arcanist can reorder magic to suit their will. Whenever you cast a spell that deals damage, you may choose the type of damage that spell deals and the appearance of the spell’s effects. For example, scorching rays made to deal cold damage might look like icicle spears, a fireball that deals radiant damage may appear to be an explosive host of warrior angels, and a lightning bolt that deals psychic damage may be a strange color or accompanied by unnatural howls.
