Just to be clear, I was interpreting the feat as channel one spell, but then I saw the post that seemed to interpret otherwise. Upon rereading it, I think it could be stretched to channel multiple spells...but then upon reading the potential for coupling it with
Whirling Blade (a 2nd level spell), it seems like it could be way too much damage. I could technically cast
whirling blade and channel three 5th level spells into each of my melee attacks. From the feat alone, that would be a +15 to hit and then additional 15d4 damage per attack. If I get a good line of opponents within range...lets say 5 opponents...that's a total of an additional 75d4 (75-300 pts) points of damage potentially in one spell action. So...my 5th level spell is
prismatic ray and I can cast three of them per day. If I cast 3 of those (instead of channeling), I could presumably luck out with 80 points of electrical damage from each one (totalling 240 pts of "guaranteed" damage), or turning to stone, or sending to another plane provided I get past spell resistance and reflex saves. And I would have cast each one separately over three separate turns. Now let's say I dump all my remaining spells (7 1sts, 7 2nds, 7 3rds, etc) into the
whirling blade...my attack bonus is off the charts. I am pretty much guaranteed to hit every target that is affected by normal physical damage and slice every one of them up like a spiral-sliced ham. Granted that is an extreme hypothetical scenario, but I cannot legitimately believe that would have been intended.
Sorry that I had to work out that math for myself...all of your previous posts all summarized this nicely. I appreciate the input. I will ask my DM, but I think I will end up with a single spell sacrifice interpretation. I am okay with that...I don't want lots of math
Thanks, all!
