Arcane Channeling (Su)

Type of Feat: Class Specific
Prerequisite: Duskblade level 3
Beginning at 3rd level, the Duskblade can use a standard action to cast any touch spell he knows and deliver the spell through his weapon with a melee attack. Casting a spell in this manner does not provoke attacks of opportunity. If the melee attack is successful, the attack deals damage normally; then the effect of the spell is resolved.

At 13th level the Duskblade can cast any touch spell he knows as part of a full attack action, and the spell affects each target you hit in melee combat that round.
