Everything they do relies on a substance to work. Typically something crude, though for the hedge wizard, his potion or personal wand is effective enough (usually, at least). Note: hedge wizards aren't the best spellers.
Each hedge wizard knows 1d4+2 spells per spell level. For instance, a 3rd level hedge wizard might have three 1st level spells and five 2nd level spells that he can select to prepare. Each one they know is drawn from a god or spirit's list (see below). What the spell is can then be chosen or selected at random, though they cannot be ones that cause any damage- at least not on purpose. Hedge wizardry is generally more subtle than that.
They can otherwise cast the same number of spells per day as a magic-user of equal level, though of course, those prepared as a component can only be cast again once they've been used or expire.
