Does that mean if your attack misses, the charge is still there the next turn?
No, the way i see it, the charge will dissipate.
For instantaneous spells, such as "Shocking Grasp", if you were to miss
every single attack for the round, the charge would be held and that would increase the duration of the spell to more than 1 round. According to the Duskblade's 13th level ability, that would cause the spell to dissipate.
You could, however, do this with the 3rd level ability.
Example:
- Attack (not a full-attack) action channeling "
Chill Touch"
- that 1st attack misses (EDIT: actually, this would work even if you hit, if you have more than 1 touch to deliver).
- charge holds.
- You are now able to perform a full attack in the next round, delivering the spell with every attack - up to the maximum of touches allowed to the spell by your level.
While we're talking about duskblades ...
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 one round.
Does the channeling last a whole round, such as for AOOs you make when it's not your turn, or does it only last for the full attack, and any AOOs you make don't benefit from the channeling?
I asked this same question some time ago... I couldn't find the topic, but here's the conclusion:
By
definition...
A round can be a segment of game time starting with the first character to act and ending with the last, but it usually means a span of time from one round to the same initiative count in the next round. Effects that last a certain number of rounds end just before the same initiative count that they began on.
(emphasis mine)
So, the channeled spell would last until the start of your next initiative count (i.e. your next turn), which would allow you to use the channeled spell for AoOs you perform until then, as well. You just have to keep in mind that you can't affect the same target with the same spell twice in the same round (the Duskblade's ability limits that).
