Afterburners: "After you fully execute a maneuver, you may spend 1 energy to perform a boost action, even when stressed."
It does not have "Action:" specifically as outlined in the Rules Reference ( http://infinitearenas.com/xw2rules/index.php?page=actions ) for it to qualify as a Standard Action. Does this imply, as I think it does, that the option to use takes place right after you finish your maneuver but before the Perform Action step of the Activation Phase?
If so this opens up allot of impromptu arc dodger and other options via a blue or white maneuver + burn an energy from the Afterburners card to perform a boost, then, in the Perform Action step, perform a Barrel Roll Standard Action (for arc dodging if on the Action bar), another action (Focus, Target lock, etc.), or a linked action series without Boost.
