You can cast spells on creatures or objects, as defined by the spell. You must have line of sight to or be able to touch the target, and you must specifically choose that target. You don't have to select your target until you finish casting the spell. You must have line of effect to any target that you cast a spell on.EffectRaySome effects are rays. You aim a ray as if using a ranged weapon, though typically you make a ranged touch attack  rather than a normal ranged weapon, you can fire into the dark or at an invisible creature, hopin you hit, as you do with a targeted spell. Intervening creatures and obstacles, however, can block your shot or provide cover for the creature you're aiming at."RC pg 80-81"Line of EffectA solid barrier cancels line of effect.  Fog, darkness, and other factors that limit normal sight don't blcok line of effect.You must have liine fo effect to any target that you cast a spell on or to any space in which you wish to create an effect.Line if SightIf you can't see the target, such as due to being blinded or the target's invisibility, you can't have line of sight to it even if you could draw an unblocked line between your space and the target's.If line of sight to a target is completely blocked, you can't cast spells or use other abilities that require line of sight to the target. When line of sight is blocked by something that doesn't otherwise physcially block or prevent an attack that doesn't require line of sight (such as fog), you can still make that attack, but your target is treated as if it were invisible. If line of sight is partially blocked, such as by the corner of a building, attacks work normally, but the target's AC increases due to cover."Empirate has it correct.Acid arrow is an effect that produces an arrow that is then treated as a ray for the attack.</blockquote>
