And that's the problem. You started with assumptions and chose the evidence to support it, rather than see all the evidence, and use Occum's Razor to come to your assumptions.
Wow. You're making a lot of assumptions about my thought process there.
I assure you, my analysis was much more rigorous that you suggest, and started with
evidence not assumptions. But I did arrive at my assumptions before I started this discussion, as did you.
But just to be thorough I did a word search on EVERY instance of the words "critical hit" in the players handbook,
and the latest errata for the PHB and DMG.
There are actually not that many references outside of feats and powers sections, but here they are.
Pg 217 - High Crit: "A critical hit deals..."
pg 276 - Critical Hit: "A critical hit deals..."
pg 276 - Example: "If she scores a critical hit, she deals..."
pg 278 - Critical hits "When... (criteria are met), you score a critical hit, also known as a crit." (this is mirrored under the Natural 20: section)
pg 278 - Critical hit damage/Maximum damage - (the result of scoring a critical hit) "...determine the maximum damage you can roll..."
SO, given this evidence, when presented with the question:
"What
is a critical hit, and what does scoring a critical hit
do?" (
NOT "how do you get a crit")
I come to the following conclusion:
A critical hit is a hit that deals maximum damage and extra damage.
My other assumptions follow from this.
Now if there are any more insinuations that I'm being disingenuous with my arguments I will have to take offense.
