Specialist Wizard

[Gee look who]

There are not many specialist wizards there, maybe because the lose too much and gain too little.

My suggestion is that a specialist wizard can cast one spell of the selected school infinitely.
As wizards need to prepare a spell beforehand, would be needed to choose the spell and then rest to get it.
This do not need to be made like the GSF feats (as a spell-like ability). It could be programmed like the trueflame
spells. When the spell is cast, it gives you back one spell slot (specifically the one that you used to cast it)

This way you could make it extended, empowered, maximized, quickened, etc, as you pleased, by spending actual
slots in preparation.

(The list of spells available may be handpicked for balance reasons, and some or all spells may have a cooldown).
