So putting it out there cuz I do love character discussion. I'm thinking Allia's school of magic will be Abjuration. The defensive and protective nature of the school seems to fit Allia's sweat and caring nature more than others. The temp hp from the ward will help keep the little thing alive in our low healing situation. Additionally considering possible multi classing her into Divine Soul Sorcerses to help supplement groups healing output. perhaps it explains why she looks so different than the rest of her family. She is basically the halfling equivalent of an Aasimar by the way I describe her after all xD
