3d10 natural attack + INA

[Stalker0]

There's a creature I have that deals 3d10 damage with a natural attack. If I were to use INA on it, what would the damage go to?

There's a creature I have that deals 3d10 damage with a natural attack. If I were to use INA on it, what would the damage go to?

Considering only the INA rules, it would have to be 6d8.

Considering the increased damage by size, it would be 6d8.

Using the weapon sizing rules, it would be 6d6, 3d12, or 6d8. Of these, I'd choose 3d12 because d12's are underused.

I would go with 4d10 because it just feels right.
