# What unfortunate side effects am I missing in allowing a feint as part of movement at a -10 penalty?

Within Mutants and Masterminds, if you have a feat called Acrobatic Bluff, you can make use an Acrobatics check in place of Bluff for the purpose of feinting to make someone flat-footed for your next attack. It is, by default, a Standard action, but the game allows you to do it as a Move action with a -5 penalty (which can be countered by a 1 PP Challenge Feat to remove that penalty). Obviously, making it a Free action for a -10 penalty can cause issues with the action economy since it's essentially cost-free (other than possibly racking up the -1 penalties to subsequent attempts against the opponent), but one of the iconic moves in the comic books is the agile gymnast doing a series of handsprings and cartwheels across the floor to confuse the opponent before striking (c.f. Harley Quinn in many of her performances).

How would allowing an Acrobatic Bluff check at a -10 penalty for doing it as part of movement break the system? Obviously, someone with a high enough bonus might be able to consistently overcome the penalty (particularly if the GM lets them buy off the penalties with Challenge Feats) and there's some risk of people doing it all of the time "just because", but it seems largely reasonable to me. Am I missing anything other than that it isn't in the book already?

I posed the same question on the Atomic Think Tank and the point was raised that the Charge action is a Standard action where you can move 30 feet and attack. Doing the Acrobatic Bluff as a Move action at the beginning and then doing a Charge is a viable action here, it seems. It feels really strange to me since mechanically it works out as "let me distract you by doing a backflip and then run straight at you and attack!" but it does achieve a similar effect and only with slight modifications to attack and defense bonuses (in 2E, +2 to attack and -2 to defense. In 3E, -2 to attack).

• Have you tried simulating some fights? I can't provide technical balance guidance (never tried the system), but since you have some ideas, actual play may help you a lot. – Kahler Apr 15 '14 at 14:15
• A little bit on my own. I'm not very good at setting up simulations. There's some good work done on the ATT on the effects in general of getting an opponent flat-footed, namely that it's devastating against characters who are defense shifted due to losing half of their bonus, and the various feint moves have been noted under "Virtual PL" problem powers where they kind of break the system enough that you might want to consider lowering the maximum effect for that character.

The biggest reason is that, as you have stated, it is primarily useful against people who are defense-shifted.

There's already a bias in the game towards toughness shifted characters since Area attacks bypass your active defenses (which isn't quite offset by the fact that active defense don't degrade as they're beaten, like toughness does).

The biggest issue that I can see is that it would let a damage-shifted character bypass the active defenses of a defense-shifted character much more easily and avoid the PL-limit imposed on Area attacks.

So an acrobatic tank could have a +20 bonus to Acrobatics and routinely make a d20 + 10 roll against a defense-shifted character's Insight/Acrobatics roll. A defense-shifted character would thus have to be either almost as acrobatic (+10 bonus or better) or extremely insightful (+10 bonus or better) to have a 50% chance to not be flat-footed.

It's an understandable thing, I think - granting the flat-footed condition as a skill check is a relatively potent thing. How badly it affects your game depends on how many defense-shifted characters there are.

Keep in mind that your player's character can always use the Set-Up advantage to transfer the flat-footed condition's benefit to another character. It's much more in-line with how comic combat works, and it actively engages characters in working together.

• Kind of a general problem with feint attacks, but I allow that allowing movement at the same time might further break the action economy. Accepting your answer. – Sean Duggan Apr 29 '14 at 20:13
