Power attack considerations


Advice


Hi there,

I was wondering, in terms of damage efficiency, the possibility to alternate different attacks. Then I gOt stuck thinking about power attack.

Both fighters, champions and barbarians ( not sure about the other melee classes ) will benefit by using this feat.

A fighter will obviously be able to score more crits than other classes because of higher proficiency.

A barbarian and a champion will simply trade a second attack with 25%/35% chance of success for a single one with double the success. And maybe a chance to crit.

I don't know during the road to lvl 20, but an ancient gold dragon has AC 46

Which means that a barbarian or a champion will have 20+7+3+6= +36 bonus to hit. Which means no crit chance. And 1/2 chance to miss or hit.

Barbarian could trade armor to gain hit in the endgame ( I don't remember the feat lvl ), but here again we are facing the wall of put all into a single attack.

Even if 2 attacks, when they 2 both occour, would be better in terms of dmg.

Also we have to remember the furious focus feat,which let you consider a power attack as -5 instead of -10,with 2h weapons ofc.

So now we don't even have to worry about the second attack.

Personally I Hardly find good reasons to make different attacks, except maybe a lunge
, Which in my opinion is pretty good, and maybe something else i forgot.

Tl;dr we probably be using attack power the whole time.

+36 to hit against AC 46 is 5% chance of critical success, 50% success, 45% chance of failure, and 5% chance of critical failure (though that's unlikely to be distinct from a normal failure).

If a party member gets in position to flank, or any of the other numerous ways of providing a bonus to an attack roll or penalty to AC that characters can accumulate come into play, you can tilt those numbers even more in favor of the attacker.


Ofc you have the naturals.

But they remains whatever and you should consider more the Normal hit chance than a natural 20, which is a 5% chance.

If it occours good, but mostly you will see just Normal hits. So let's stick with this instead of a too many random scenario.

Also what you said about lowering enemy armor doesn't change the fact that power attack with furious focus feat will still be the best choice.

Unless you want to go for a this attack ofc.


Power attack is generally a damage decrease except against targets with high AC relative to your attack bonus.

The other thing to consider is that on level challenges are supposed to be challenging, typically you're intended to fight things 1 or 2 levels below your level for "non-challenging" encounters, these should make up the bulk of your "daily fights" with mini-bosses potentially being of level, and bosses potentially being 1 or 2 levels above (be careful because it can be dangerous).

Doing some math on a greatpick wielding fighter making two regular iterative attacks at level 20 vs AC 46 average damage should be about 37.4. Making a power attack (cost two actions) gives average damage of about 33. Slightly worse.

Power attack is useful if you have to go against DR, but is otherwise generally worse than making two regular iterative attacks. It's no longer a must have.

If you're really interested I can post the damage calculations, but I believe they are correct.


I am just trying to understand.

About the calcolation you made, it is ok to say that power attack uses 2 actions, but we can say tha if we compare 2 scenarios

1) first

-first attack > power attack +36 hit
-second attack > attack + 31 hit

2) second

-first attack > Normal attack +36hit
-second attack > Normal attack + 31 hit
-third attack > Normal attack + 26 hit

All vs 46 ac

I don't get how the first rotation would be worst than the latter.

Also, even if we were facing lower lvl enemies. Let's say with 42 AC, it would be always the same. The first hit will have higher chance to hit and could eventually crit. Same goes for the second one. While the last one will only have 25% chances to hit.


When you want to have a lot of crits go double slice.

At redit is a detailed power attack Analysis.


That's a really good idea.
Even if a see some issues:

First, you have to get 2 weapons, which means 2x any enchantment you want to get. Basically, you pay it double.

Second, to have no penalties, your off hand must have the agile trait. Which means Pick in main hand and light Pick in off hand.

Finally, it counts as 2 Strikes when it comes to attack penalty.

It is not bad as build, but if the second attack after power attack hits, then difference would be huge.

You could eventually forgo an agile weapon and go 2x medium Picks, which would be a huge dmg.

Or eventually hope to hit with your third attack using the off hand.

Gonna check the Reddit thread.
Thanks


There is a rune which mirrors the runes from your main weapon. So, you don't have to get all runes two times.

With double slice you have 2 attacks without MAP. The third and second attacks are not very helpful, when you want to fish for crits.

You rarely have a third action to attack. But you're right that in that case, Power Attack may end up being better than not power attacking.

Without map if you have an agile weapon as offhand.

And if you want to fish crits, you are likely to do it with a pick, and weapon specialization with Picks.

The second attack could not be useful for crits, i totally agree. But if you have a -5 instead of a -8 or -10 you have high chances to score a hit. Some more damage.

I say this because even though we are talking about crits, we have to consider the damage on the whole turn.

Ps: The rune which mirror your main weapon is good. I wonder of it would work with divine ally and the fourth rune.


Yes, if you compare Power Attack + a second attack with Furious Focus then you might come out ahead of making two strikes.

However, as Superbidi pointed out you rarely are going to want to spend all 3 of your actions in a turn making attacks. I would have to run the math for 3 strikes vs Power Attack + Furious Focus strike. In that scenario Power Attack might will probably come out ahead, but that math doesn't account for the Action Economy cost of dedication all 3 actions to attacks (and the math cannot do so).

I simply compared two strikes (for two actions) to Power Attacking (which costs 2 actions).

The strikes only routine also isn't using any feats to enhance the fighters capabilities in any way, so you have to look at things like Certain Strike or Intimidating Strike, which it's hard to do a comparison against since the effects aren't simply damage.


The average damage is higher with attack+exacting strike+attack then power attack + attack.

The item which mirrors Runes onto your second weapon is a ring. If it were a Rune, that would be a loss of weapon effectiveness because you wouldn't have that slot for a damaging Rune.

Power Attack is a good, low-level way to break items and get through hardness & DR (as are some other feats which stack damage). Since retraining is a normal mechanic in PF2, Power Attack has its time to shine before being put on the shelf.
The existence of Furious Focus though, makes me wonder if PA is meant for long term use.

Also, Power Attack has to be balanced around a PC with a d12 weapon, so I'd expect other weapons would be sub-par automatically (even if the difference is incremental).

And there are corner cases, like if fighting a creature w/ a fiery aura, spikes, or say a Rust Monster and you want to hit it as few times as possible while still killing it.

power attack coutns as 2 attacks for MAP.

so its

1) first

-first attack > power attack +36 hit
-second attack > attack + 26 hit

2) second

-first attack > Normal attack +36hit
-second attack > Normal attack + 31 hit
-third attack > Normal attack + 26 hit

Quote:
You unleash a particularly powerful attack that clobbers your foe but leaves you a bit unsteady. Make a melee Strike. This counts as two attacks when calculating your multiple attack penalty. If this Strike hits, you deal an extra die of weapon damage. If you’re at least 10th level, increase this to two extra dice, and if you’re at least 18th level, increase it to three extra dice.

edit: ah i see people are expecting you to have furious focus.

Yeah, if you make 2 attacks with power attack and furious focus there is potential for it to be better than strike + strike + strike. But if a fighter is making 3 strikes instead of using their class feats I would hope the routine using class feats is better, else it means they're actively bad choices.

But the problem is that many turns there is a chance you wont be able to use all 3 actions to strike. That will depend heavily on how your GM runs combats, but as an example my group now has much more mobile combat. Non-melee combatants don't stay next to a melee combatant, at least until they see they have AoO. And now we run everyone as not assuming AoO exists until they're used by someone. PF1 had the habit of everyone just locking in place until they died because of AoO. In the sort of game I'm currently playing in 70% of turns involve making at least one stride per turn. Basically every turn involves doing something besides spending 3 actions to make attacks.


Furious focus is mandatory as hell!

which is why i kinda assumed people wouldn't be taking it, power attack is really only great if you're overcoming DR or hardness, and only with a very large damage dice.


power attack is good as a second attack with minus 5 to hit then statistically better than an additional hit with -10 to hit


Power attack as first attack (with Furious Focus and a second attack) is mathematically better than regular attack first and then power attack.

The accuracy loss to the more damaging of your two attacks is significant.

If I were giving fighters general advice it would be only to use power attack when you are trying to overcome hardness or DR and not otherwise.

You get enough class feats that you could drop one on Power Attack and not be too sad if you only used it occasionally, but I personally think Sudden Charge and Exacting Strike are much better choices.

Yeah. Honestly I always saw exactly that as Power Attacks niche. To overcome heavy defenses, either good AC or resistance (or defensive reactions). PF2 actually manages to make PA fill that role.


I prefer to use power attack + furious focus and then a second attack.

Eventually I can trade the second attack for a true strike, but because of the fighter higher attack ratio, is usually better to strike twice.

First with power attack
Second with a Normal one.

If you find that mobs tend to move away from you and you are not able to use 3 actions to attack, you could consider to use haste, from spell/wand or whatever.

Ring of wizardly could help you mantaining haste 3+ fights per day.

So you could even dedicate 1 action to stride.

Eventually, you could consider a reach weapon.
