I think the reroll power has to be used up before it comes back into your pile of powers; I would rule personally that means that the original power you are rerolling has to resolve one way or the other.
The text of Combat Challenge doesn't specify that they have to be the fighter's marks though; I think this may be a loophole. I agree that currently a multi-classed F/P would work as you describe.
Hm, that creates a double jepoardy situation for someone marked by a paladin who has a fighter adjacent. Non-stacking marks was done to avoid those situations; I think it is likely that the intent would be for only the fighter's own marks to trigger the extras from Combat Challenge.
Powers that mark targets just inflict the marked condition. They don't come along with all the fancy extras that happen when you mark someone with Divine Challenge or Combat Challenge, even if you aren't multiclassed.
I think a more useful direction for this thread to go would be identifying those 'specific exceptions' that achieve optimal status without going for a post-racial 18.
We know of the following from the thread so far:
tiefling warlock (infernal)
dwarf fighter
What else is out there that qualifies?
I'm not sure why I should think the fact that a bunch of monsters from Greek myths have Greek names (truly shocking) has anything to do with scholars naming monsters.
I'm firmly in the pro-behemoth camp. Naming things the same way modern scientists do is a bit immersion breaking for me.
4e cleric fluff indicates that the cleric draws his power from his investiture more than directly from the deity. Granted, you might want to discard that as it is a decently large change from before.
Given the mechanics of 3e turning, I am having a hard time imagining a character who has only...
A short rest takes 5 minutes, so if they were taking a rest during that 8 minute gap, then all the things that go along with a short rest (encounter powers recharging, etc.) would apply.
The rogue Garrotte Grip power, pg. 123 in the PH, gives an example of the way 4e would handle this sort of thing, like the 'use as a shield' thing. Grabbing, that anyone can do, is sort of a generic maneuver. To do anything fancy, that's a power.
Well, that's not quite right - you can pick prayers up after the fact with the later power swap feats (and paragon multiclassing or hopping to a cross-class paragon path.)
Have you played much 4e? What feels like the defining characteristic of the leader role classes in actual play is...
It can also pay off, in theory, if you're willing to stick it out with a full multiclass build, where you can pick that 3rd at will up at 11th level that uses your primary stat from your multiclassing choice.
