What does this feat do? As far as I can tell the only effect, mechanically, is that your character saves 5 SP by not having to buy a Material Component Pouch. You still need to have a hand free. You still need to pay the price if a spell has a listed cost. If you have a component pouch it automatically refills after resting so eschew materials doesn't help there either. Sorcerers and, I believe, some other classes get this for free but a wizard can select this as a feat. Why?
