I have honestly no idea what are you talking about ...
What supports another class? O_o
Are you talking about metamagic?
That is how Sorcerer buffs his own spells ... not anyone else. O_o
The spell list, it looks like they create buffs and since no damage spells were listed I'm assuming those are to be applied to another party member? I don't know anything about D&D, I'm just trying to interpret what those spells would be used for in a party of four? I still haven't had an answer to my legitimate question. What practical benefit does a Sorcerer bring that a Wizard cannot? If I chose a Sorcerer as my character's class, how will the game play differently than if I chose a Wizard? They look almost identical to me and it seems to me the OP wants the class' inclusion because it's part of the lore rather than because it would bring something unique to the game.
