The thaumaturgist delves into the secrets of summoning, enhancing the power of conjured creatures and calling forth allies from beyond mortal realms. Devoted to the art of summoning, a thaumaturgist forges pacts with extraplanar entities, strengthening their summons and expanding their magical reach.
