A question for those who allow vital strike on a charge

[Beorn the Bear]

I allow charge attacks to be resolved with vital strike feats. I was looking at a build I was working on for a mounted character, and the lance and spirited charge feats multiply damage on a charge. How would you rule this interacts with the vital strike damage? does only the base damage get multiplied on the charge from these abilities, or would the vital strike damage as well?

You do not multiply extra damage dice from vital strike. Not opinion, you never multiply damage dice other than the original base dice. Basically just tack the bonus roll on after you do the spirited charge damage.

Edit: I found the rule

Multiplying Damage: Sometimes you multiply damage by some factor, such as on a critical hit. Roll the damage (with all modifiers) multiple times and total the results.

Note: When you multiply damage more than once, each multiplier works off the original, unmultiplied damage. So if you are asked to double the damage twice, the end result is three times the normal damage.

Exception: Extra damage dice over and above a weapon's normal damage are never multiplied.

Because the vital strike specifically says that the extra damage is not multiplied on a critical hit (but rather added to the total), I think it would make the most sense to do the same with damage multipliers from a charge.
