His text says:

When attacking at range 2-3, you may spend 1 evade token to add 1 hit result to your roll.

What exactly does this mean.

A. You get to change one of your dice to a hit if it was a blank or eyeball.

B. I take an extra die and place it into the pool with the rest of your attack dice that I rolled. So if I rolled 3 hits I would now have 4 hits?

I am led to beleive that its option B because all of the cards that change the results of a rolled die say that you change a blank to a hit/focus.crit or change a focus results to a crit/hit results.

For all intents and purposes, B is correct. In reality you would just treat the token as the extra hit, but using a die as proxy works fine. I don't believe there are any abilities that doing that would be confusing.

Edit: just keep in mind the hit added is *not* a die: it cannot be rerolled, etc.

B is correct-ish.

Basically, the way that an Evade token would apply to defense, Kir Kanos may also apply to offense.

Indeed, it's not a die to be rerolled. It is simply an "added" hit result and a die is being used as a token/marker. Because this happens in the Modify Attack Dice phase, I tend to place it separate from the rolled results, in case the defender has any abilities that modify my dice.

Wouldn't this be considered an ability that modifies attack dice? So the defender would do all his modifications of your dice before you even get to use Kanos' ability. Right?

Absolutely, but we play pretty casually here, so I tend to put the result out there just after I roll anyway. If the defender's got anything to adjust, we know that the odd die on it's own wasn't rolled with the original roll. Works OK for our group.
