Narrator:
move through fire and attack does not get you a shit ton of dodges
Unless Gareth took an All Out Attack, kicked while doing a Committed Attack, or made any attack that isn't an "arm" attack
1 while doing a Move and Attack... he can Dodge every attack he is
aware of.
Dodge can get very broken with Swashbucklers and Martial Artists when that Dodge score inches up into the low teens, since it doesn't negatively increment with usage (I consider any Dodge above 11 to be entering 'broken' territory personally, but in a DF game, I'd allow it).
1 - Basically as per Martial Arts, if you attack with a hand or hand armed weapon, you can Dodge, if you make an attack that employs any other body parts: foot, head, mouth, butt, knee, groin, etc, you cannot Dodge (this includes slam attacks as that requires your body).
I usually treat Committed Attack the same way, but then I also broadcast that in my House Rules so it's known in advance.
Amelia Montaigne:
Don't Dodges count as reactions to incoming attacks and, assuming not stunned etc, are independent of a PC's move/maneuvre?
Yes and no. They are reactions, but whether or not you
can Dodge does depend on the Maneuver you take, as noted above, some Maneuvers (plus attack method) preclude Dodge entirely and others penalize it (Committed Attack all allowed defenses are at -2, Do Nothing [Stunned] all defenses are at -4).
Also, Dodge used to be "an abstraction that includes 'passive defensive' movements, not just actively dodging", as that was the old excuse for why you can dodge
bullets and lasers in GURPS. And in Martial Arts, Dodge is described in a few places as being an abstraction that could be "body parrying" in close combat (ie, parrying a grab or other grappling attack by twisting, or interfering with the attempt, but not actually moving from the space).
