It was stated earlier that a level 1-3 ranger can use wands of ranger spells, despite being yet unable to cast them. Are scrolls explicitly different from wands in this regard? Where exactly is it stated that having the spell on your class spell list, but having no caster level, means being unable to use a spell-completion item? I would have assumed that the ranger could cast the spell, but his caster level check would be a straight d20 roll since his caster level is nonexistent.
