Mythic Abilities Stacking

[Stuart Waring]

Hi All,

We are playing with the mythic rules, and i am curious about how certain abilities stack together.

Note that this is a with a level 20 Tier 10 character.

The things i am particularly interested in are Perfect Strike (path ability), the Foe-Biting ability that can be placed on a Major Artifact Legendary item (My theoretical character is wielding a +5 Holy, keen sword), and the Critical Master path ability

Foe Biting doubles the damage, including the 2d6 vs evil (for evil creatures only obviously)

Perfect Strike also doubles damage AND raises the critical multiplier by 1.

Being as i have Improved Vital Strike and Power attack, my normal damage is 3d6 + 90 (+2d6 vs evil)

i see a number of possibilities all of which are fairly ludicrous (best one outlined below).

The best case scenario: Foe Biting & Perfect strike add to x3 (rather than x4 - think i read about this somewhere in core rules), which is then tripled by the crit multpilier, giving a total of 1080 damage for a single hit (3d6 + 2d6 maximised by Crit master = 30 + 90 = 120, x3 (Foe Biting + Perfect Strike) = 360 x 3 (Crit multiplier) = 1080!!!!)

For the record that is enough to kill all CR30 monsters in a single hit.

I know it could simply be banned as a house rule, but if it is possible i would love to try it once just to see my GM's face.

Any ideas on how to resolve this (or a reference to a core rule specifically preventing this kind of stacking specifically sought!)

Things that double multiple times don't straight double. They simply increase the multiplier by one. So, 2 x2 abilities are really a x3 ability.

Multiplying: When you are asked to apply more than one multiplier to a roll, the multipliers are not multiplied by one another. Instead, you combine them into a single multiplier, with each extra multiple adding 1 less than its value to the first multiple. For example, if you are asked to apply a ×2 multiplier twice, the result would be ×3, not ×4.

Foe-Biting: When this item deals damage, its user can use mythic power to double the total amount of damage it deals. If the attack is a normal attack, the bearer can expend one use of legendary power to double the total amount of damage. If the attack is a confirmed critical hit, the bearer must instead expend two uses of legendary power to double the total damage. Damage from weapon special abilities (such as flaming) and precision-based damage are also doubled.

This ability can be applied only to weapons. An item must be a minor or major artifact to have this ability.

I would argue that foe biting is phrased such that it should be applied last after all other calculations, but otherwise agree with Buri.

Basically a crit would be for you (((5d6 + 90) * 4) * 2) at the cost of two myth power.

This is the logic I think I have applied above, so are my calculations correct?

Thanks for the input

You seemed on the fence. Just providing the reference. :)

Thanks Covent - can you please run me through how you got the *4 then *2 at the end?

Even on an average dice roll (15), you would be talking about 840 damage - still enough to kill all the CR 30 monsters in a single blow.

NP. A x2 weapon goes to x3 due to crit multiplier increase from perfect strike and x4 from perfect strikes doubling. Then after all other calculations the total damage would be multiplied x2 when spending two myth power to activate for biting.

As perfect strike is missing the total damage wording from foe biting, I belive it just acts as another normal crit multiplier.

This is just how I read it.

That makes a lot of sense, thanks.

Including the Critical Master ability, and you get 960 damage on a confirmed critical hit. Nasty.
