Improved Natural Attack, Strong Jaw, Stonefit Gloves and Behemoth Hippos

[Jadeite]

How much damage would a Druid with Improved Unarmed Strike, Weapon Focus (bite), Improved Natural Attack (bite), Improved Unarmed Strike, Feral Combat Training (bite), Strong Jaw and Stonefist Gloves deal with a bite attack while wildshaped into a behemoth hippopotamus?

[Drakkonys]

With Improved Natural Attack (bite) you'd have 6d8 with a bite attack. I assume Strong Jaw would double the damage to 12d8, seeing as there's no fixed value on the table. It does say

"If the creature is already Gargantuan or Colossal-sized, double the amount of damage dealt by each of its natural attacks instead."

Also, if you look up under Improved Natural Attack description you'll see that 6d8 scales to 8d8 then to 12d8. That's two size categories larger.

Stonefist Gloves double your unarmed strike damage, and here you have a natural weapon so they would not apply. Feral Combat Training does not increase damage from natural weapons and it's used for monks who have natural weapons (a lizardfolk monk, for example).

Improved Unarmed Strike, Weapon Focus (Bite) and Feral Combat Training (bite) would have no impact on the damage you deal while wild shaped since unarmed strikes do not count as natural weapons.

You were taught a style of martial arts that relies on the natural weapons from your racial ability or class feature.

Prerequisites: Improved Unarmed Strike, Weapon Focus with selected natural weapon.

Benefit: Choose one of your natural weapons. While using the selected natural weapon, you can apply the effects of feats that have Improved Unarmed Strike as a prerequisite, as well as effects that augment an unarmed strike.

Special: If you are a monk, you can use the selected natural weapon with your flurry of blows class feature.

These heavy, stone gloves feel surprisingly supple to anyone who puts them on. While a creature wears stonefist gloves, his unarmed strike damage is treated as if he were one size category larger, and bypasses hardness of 8 or lower. When a mythic creature uses these gloves to make a sunder combat maneuver, he adds half his tier as a bonus on the combat maneuver check.

Construction Requirements

Cost 5,000 gp

Craft Magic Arms and Armor, Mythic Crafter, stoneskin

Yes, but hippo's bite attack (as well as all animal attacks) are natural weapons, not unarmed strikes.

[Jadeite]

Feral Combat Training (bite) would apply effects that augment unarmed strikes to the selected natural weapon (bite).

Don't both Strong Jaw and Stonefist gloves have the effect wording of, "as if x size categories larger"? If so only the greater effect should work.

Weapon Special Ability, Impact: Does this stack with the lead blades spell?

No. The weapon special ability and the spell are similar effects; note that impact lists lead blades as a construction requirement.

Since Stonefist Gloves have Stoneskin as a prerequesite, it should work.

[James Risner]

A case can be made that the "as if X size larger" effects do not stack.

FCT also allows the unarmed damage dice to override the Bite damage dice, but would not allow you to increase the size of the Bite damage dice. Use the Monk Unarmed Damage case with FCT. It allows you to use Monk unarmed dice instead but not increase the naturals.

Correct. They don't stack with improved natural attack either btw.
