Price of Limitation "One Attack Only" in Defenses

[NaiveWanderer]

TLDR: How much would the Limitation "One Attack Only" worth for Defenses? LIke, this Defense only works once, to reduce single Attack?

I'm trying to make a "temporary invulnerability" skill where a character could survive even the most absurd attacks just because he got "lucky."

Checking Powers, I liked the suggestion of using Injury Tolerance (diffuse) i liked especially because this advantage doesn't protect you against area damage! (I pictured the power as being something that could be justified as a "glancing blow" and so it wouldn't work against things like explosions)

This was my first attempt:

Injury Tolerance (Diffuse) [100]

• Emergencies Only, -30%
• Limited Use (1/day),-40%
• Reflexive,, +40%
• Require awareness, -20%
• Unreliable (activation 14), -10$

But then I realized, reading Limited Use that "For most advantages each use is 1 min of activation." Well that's not exactly what I was thinking, that way the character be "invulnerable" for 1 minute?!

So I applied "Duration Reduced 1/60 by -35%" But that still doesn't seem right to me, after all with that the advantage would still last the entire turn, and I would like it to last only for one attack.

There is already a "One attack only" limitation for Striking Strength for -60%, but this seems too much compared to -35%. How much would a fair price be for that single limitation?

"One Attack Only" on Striking ST is specifically to make it so that one attack mode you have - a kick, a Natural Weapon, etc - is the only thing the boosted ST applies to, but it applies every time you use it.

As for your build, if you want it to only last for an instant, use Reduced Duration 1/100 -40%. This makes it last less than a second (specifically, 0.6s), and thus can be treated as lasting only long enough for a single action - a defense in this case. Do note that this results in a net -100%, which gets capped to -80% - you may want to reconsider some of your other Limitations to get it closer to -80% to start with.

There's a modifier in powers under "Requires (Attribute) Roll" called Active Defense. It seems obvious to allow it to activate as a defense as part of the limitation. You also don't need (and shouldn't add) Unreliable, since this mod comes with a built in activation roll of DX/2 + 3 (+CR if applicable).

So, it becomes:
IT: Diffuse (Active Defense -40%).

You can further add 1/Day (-40%) if you only want to be able to make the attempt 1/Day.

(Yes, IT isn't listed under Force Field, but in this context as a self only defensive ability it works like the other *Tolerance traits).

EDIT: FWIW, I also would allow a power talent to add since it does for all the powered (Power Dodge, Power Parry, Power Block). I'd also consider it a Block action if you want to buy enhanced block as an advantage as well.

The Limitation usually doesn't permit this but i think yes i can use -40% to emulate "towards only one attack" thank you! I will try to tone down the limitations too hehe or put some enhacenments

I am tryna not put Active Defense because it's for a character who most always use All Out Attack! in fact the advantage is only being made bc he is the type of character to escape dangers barely alive (but escaping it, indeed!)

Considering the character is meant to simply be getting lucky, getting rid of Requires Awareness -20% would fit - characters like that are typically harder to manage a sneak attack on as well. But I think you may be underestimating how often the character is likely to be subject to potentially-fatal Injury if he's constantly All Out Attacking. Some degree of Luck, Limited to forcing attackers to reroll their attacks when they hit, might work a bit better, at least against ranged attacks (melee attacks are likely to be around skill 16 unless the foes are amateurs or are taking penalties for hit locations, as an All Out Attacking foe is a prime target for a Telegraphic Attack; with succeeding 3 times with skill 16 is only marginally harder than succeeding once with skill 15, so it doesn't help much there). It would be both cheaper and available more often to boot - Luck starts at [15] (while IT:Diffuse cannot go below [20]) and is available once per hour of play time. Only working to make foes reroll attacks is worse than any of the -20% options (notably, Combat -20% would automatically include that option but not be limited to it), so probably -30% or -40%.

The no defense is a fairly serious limitation as to what you can take. Warp (Blink Only, 1 yard step only) would fit nicely, but it's considered a dodge.

Have you considered Serendipity? A coincidence to move you 1 yard out of the way of a fairly nasty hit seems like a fair ask. You can even throw on Cosmic +50% and Emergencies Only -20%, then round it up to 20 to arrive at a similar point cost as IT w/-80% worth of limits. Of course, you trade 1/day for 1/session, but it seems like a fair trade.

I'd go with Luck (Wishing, to use after the fact +100%; Emergencies Only -30%; Protectively only - to make enemy attacks vs the PC reroll -20%) at whatever level you can afford rather than doing the 1/Day thing. Some combats drag long enough that you could use Extraordinary a couple of times in an encounter or Ridiculous every couple of rounds.
