I'm running a Gestalt game. One of my PC's is a Barbarian 12/Duskblade 3//Beguiler 14/Mindbender 1.
If he used Eclectic Learning (variant of Advanced Learning from the PHB2) to pick up Celerity as a known Beguiler spell, and then channeled Overwhelm into his sword, missed with his attack, then cast Celerity as an immediate action (essentially as his swift action for the same turn) to get an extra standard action, would his channeled spell still "hold the charge" on the Overwhelm spell, since his turn has not yet ended?
Arcane Channeling (Su): Beginning at 3rd level, you can use a standard action to cast any touch spell you know and deliver the spell through your weapon with a melee attack. Casting a spell in this manner does not provoke attacks of opportunity. The spell must have a casting time of 1 standard action or less. If the melee attack is successful, the attack deals damage normally; then the effect of the spell is resolved.
At 13th level, 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. Doing so discharges the spell at the end of the round, in the case of a touch spell that would otherwise last longer than 1 round.
Also, you are never able to "hold the charge" on a channeled spell, correct? It doesn't ever last beyond your current turn?
*In full disclosure, the Beguiler would actually be using 3.0 Haste, granting an extra standard action per round. I just framed the question with Celerity, so that it was applicable to 3.5 RAW.
