The more I think of it, the more I think they got scrolls and wands backward.
Now I just hope someone sees this buired on page 5 or 6.
I would put Scrolls, Potions and Oils all togather as 1 item set. spells that effect yourself (healing, hasting, heroism) are potions you drink. Spells that effect objects (magic weapon, mending, holy weapon) are oils you apply, attack spells (fireball, dispel magic, evards spikey tenicals of forced intrustion) are scrolls you read. Each one holds a spell and casts it once when used. Only some spells can be made this way...like they said about wands
Wands and Staff have spells in them permently. Wands allow swaping only, so a wand of cure light means you can swap any 1st level spell for a cure light. a wand of dispel magic means you can swap any 3rd level spell for dispel. each wand holds 1 spell, and 1 spell only.
A staff on the other hand is way more powerful, it holds a handful of simalar themed spells, and functions as a wand holding all of them, BUT it also allows 1/per day a free casting of 1 of those spells and holds a prorperty to boot.
Ex:
Your fighter can have a potion of cure light, an oil of flaming weapon, and a scroll of dispel magic to go with his magic sword and armor.
Your cleric can have a wand of Cure light so he never has to prep it again
Your wizard can have a Staff of fire that holds Burning hands, scorching ray, and fireball so he never has to prepthem, and can once per day use one, and as a special property well he holds it he has fire restance equal to his Int modifier.
