If I crit with Mythic Power Attack and Mythic Vital Strike, how much damage do I do?


Rules Questions


For sake of simplicity, let's say I'm hitting with a regular longsword, +1 BAB, no strength bonus (I know the numbers aren't possible, but that's not important for hypotheticals).

Standard MPA hit: 1d8+3
Critical MPA hit: 2d8+12

Standard MVS + MPA hit: 2d8+6

Now, with MPA, the damage that would normally be multiplied on a critical hit is double the non-critical damage bonus. 6 points in our hypothetical example.
So does that mean the Critical MVS + MPA is;
3d8+18 (1d8+6 for vital strike, plus the 2d8+12 for the crit)
or would it just be;
3d8+15 (1d8+3 regular damage, plus the 2d8+12 for the crit)?

Extra hypothetical
Since Mythic Vital Strike states that you add the damage bonus that would normally be multiplied on a critical hit, and Mythic Power Attack adds double it's normal bonus on a critical hit, would Mythic Vital Strike in fact always add double the usual Mythic Power Attack damage? (so 1d8+3 + 1d8+6 in our example)?

Power Attack (Mythic):

Benefit: When you use Power Attack, you gain a +3 bonus on melee damage rolls instead of +2. When your base attack bonus reaches +4 and every 4 points thereafter, the amount of bonus damage increases by +3 instead of +2. In addition, the bonus damage from this feat is doubled on a critical hit, before it's multiplied by the weapon's critical multiplier.

You can expend one use of mythic power when you activate Power Attack to ignore the penalties on melee attack rolls and combat maneuver checks for 1 minute.

Vital Strike (Mythic):

Benefit: Whenever you use Vital Strike, Improved Vital Strike, or Greater Vital Strike, multiply the Strength bonus, magic bonus, and other bonuses that would normally be multiplied on a critical hit by the number of weapon damage dice you roll for that feat.

Extra damage from sources that wouldn't normally be multiplied on a critical hit isn't multiplied by this feat.

The way I read it given your example...
Normal longsword damage with Mythic Power Attack would be 1d8+3.
A Critical Hit with Mythic Power Attack would be (1d8+3)x2, or 2d8+6.
A Critical Hit with Mythic Power Attack and Mythical Vital Strike would be ((1d8+3)x2)+(3x2)+1d8), or 3d8+12.

Note that the Mythic Vital Strike states that you gain additional damage for the number of weapon damage dice you roll for this feat, ie for the Vital Strike feat. When attacking with Mythic Vital Strike, you are actually using Vital Strike and Mythic Vital Strike is augmenting it. Therefore, since Vital Strike adds one damage die for a longsword, the Mythic Vital Strike adds a +3 bonus from Mythic Power Attack that is multiplied by the longsword's critical bonus if x2.

Let me add that I have not used Mythic rules in our game and I am only giving analysis on how I see these two feats interacting with a Critical hit.

I believe there should be one mythic power attack iterative thanks to this line:In addition, the bonus damage from this feat is doubled on a critical hit, before it's multiplied by the weapon's critical multiplier.

So a crit in this example would be 2d8+12. (bonus dmg doubled on a crit 3x2=6, which is then doubled by the x2 multiplier)

Now with vital strike I have no idea about the static bonus. It will be 3d8 + 18 or 24 would be my guess. I would lean towards +18, but I think mythic needs reigning in where ever possible.

Or just call your opponent dead. Most people have gotten rid of the odd line in mythic power attack, especially as it isn't repeated in deadly aim.


Enough.


Vital Strike only adds dice; it doesn't mix the bonuses in. Mythic Vital Strike multiples your static bonuses (the ones that would be multiplied in a crit) by the number of dice you gain from using a Vital Strike (by RAW, the "weapon damage dice you roll for this feat.")

Thus:

Base = 1d8.
Vital Strike = +1d8.
MPA = +3.

Normal hit: 2d8+3.

Crit:
Base = 2d8.
VS: +1d8.
MPA = +12.

Critical hit: 3d8+12.

-----

Now let's suppose a 15th level fighter with Str 20 (+5). You'll have +12 (base!) from your MPA. You're wielding an Estoc+3 one-handed, which is 2d4 base damage and x2 on crit damage. You're also using Greater Vital Strike.

Base: 2d4
MPA: +12
Str: +5
Weapon enhance: +3
VS: +6d4. Now since we're getting 6 dice for the feat, we get x6 on our bonuses.

Normal hit: 8d4 + 120.

Crit:
Base: 4d4
MPA: +48 (doubled, and redoubled for crit)
Str: +10
Weapon enhance: +6
VS: +6d4 (VS doesn't give MORE dice on a crit.) Still x6 on our bonuses.

Prepare to faint: 10d4 + 384.

Hope that helps.

I could disagree with your premise but it doesn't matter too much. Welcome to mythic where the rules are even more incomplete.

As for the 15th level example (with a very low strength), just add in foe-biter and that's how and why demon lords get killed in one shot.

I know it's low. I just wanted to keep the numbers simple rather than realistic. :)

Most people will NOT play with 2d4 dmg weapons Mythic Vital Strikes adding 2x the modifiers of 1d8 Weapons.

If this is true, then Large Greatswords (3d6) or Huge Ones (4d6) are definitely your dream weapons, because they deal x12 and x16 damage with Mythic Greater Vital Strike! Which I don't think they do, or those Mythic Dragons just one shot everybody with base 6d6 Greater Vital Strike bites doing x24 damage.

Simply put, Just multiple the weapon damage when Mythical Vital Striking by the Vital Strike modifier.

So, basically, you're doing x2, x3 or x4 damage.
The line about 'as if it were a crit' is so you don't add in damage dice from things like Sneak Attack.

Mythic Power Attack will only add to a Critical Hit and will have no effect whatsoever on a Mythic Vital Strike. The crit damage is added after the fact.

The reasoning being...?


This is how everything interacts.

1. Vital Strike adds a number of weapon-base damage rolls based on feat rank:

VS - 1 set
IVS - 2 sets
GVS - 3 sets.

2. As RAW, Mythic VS multiplies your total static bonus by the number of damage dice "rolled for {Vital Strike}."

3. Mythic Power Attack modifies Power Attack so that it gives you a static bonus of 3 + 3 every 4 BAB you have; and doubles this value when you confirm a crit, and before you apply the crit.

@Throne: The reasoning being that it's the other way around: Mythic Vital Strike applies its effect to static damage bonuses, including the one from Mythic Power Attack.


I don't know what you are asking properly. But if I was to just answer the title of this thread, the answer would be simple.

Example my large nodachi is 2d8 damage, 18-20/X2. I have both Mythic Power attack and mythic vital strike. I have +6 str and +9 BAB, no other bonus just to keep it simple.

My normal damage (2d8+{9 from str with two handed weapon}+[13 from mythic power attack rounded down]) = 2d8+22 (one set)

If I crit with nodachi, it's X2. So it's 4d8 +44 (2 sets)

If I just Vital Strike, no crit. It's 4d8 +44 as well. (2 sets)

Now if I both vital Strike and crit. It's (2d8+22 from normal +{2d8+22 from crit}+[2d8+22 from vital strike])= 6d8 + 66 (3 sets)

If I get improve vital strike, I add one more set, if I get greater, I add another set on top.

I think that's how it work.

If you crit with MPA, your PA bonus is doubled.

With +9 BAB and two handed weapon your PA bonus is
+3 x1.5 (2-handed) = +4.5
x3 (for +9 BAB) = +13.5 rounded down to +13.

On a critical hit it becomes
+3 x1.5 (2-handed) = +4.5
x2 (for MPA crit) = +9
x3 (for +9 BAB) = +27

And finally your crit with your large nodachi is (2d8+27+9)x2 = 4d8+72.
I think the MVS additions are correct, (2d8+22 for each feat) :
MPA+MVS = 6d8+94
with Improved VS = 8d8+116
with Greater VS = 10d8+138

Yeah, it's quickly becomes many numbers crunching and I advise my players to have a sheet with all possibilities calculated ahead in advance in order to save time during combat situations.
I do the same for NPC and enemies.

That's why I was keeping the numbers as simple as possible, with one just one weapon dice, just the basic MPA bonus, and just the first Vital Strike feat :P

All other permutations can be iterated out from there.

But yeah, basically, the question amounts to 'does Mythic Vital Strike multiply Mythic Power Attack's doubled-on-a-crit bonus, or just the base bonus?'


It would, because Mythic Power Attack (even on a crit) defines part of the static damage bonus. Mythic Vital Strike multiplies the static damage bonus.


That seems to be the consensus.
