Duskblade, Arcane Channeling and Natural Attacks

[Yogibear41]

At 13th level a Duskblade gains the ability to have his touch spell affect everything he hits with an attack. I see no where in the description that implies that if a character is using exclusively natural attacks (not unarmed strikes) that each would not trigger the spell. For example if a duskblade used shocking grasp and hits 3 separate enemies, 1 with a claw, 1 with another claw, and a 3rd with a bite, would he get to inflict each one with shocking grasp? Or would it apply to only 1 of the attacks since he can only cast it into one "weapon"

Nothing in the ability suggests the duskblade casts the spell "into a weapon." It seems pretty clear: "You can cast any touch spell you know as part of a full attack action, and the spell affects each target you hit in melee combat that round." Claw and bite attacks are melee attacks, so all three creatures would get zapped.

Cool that is what I thought, thanks.
