Mammoth Hide Armor Mounted Charge

[Cubed]

Does the Mammoth Hide Armor (Melee Tactics Toolbox p. 23) damage bonus apply to mounted charges? While Rhino Hide Armor (Ultimate Equipment p. 129)
specifically states that the additional damage applies to its mounted charges Mammoth Hide Armor does not.

Mammoth Hide Armor:

This +2 hide armor is made from woolly mammoth hide.
It seems to move with and bolster the wearer, and has only
a –1 armor check penalty. Once per round, when the wearer
makes a successful charge attack, the mammoth hide deals an
additional 3d6 points of damage to the target. This damage isn’t
multiplied on a critical hit or by effects that multiply the damage
of a charge, such as Spirited Charge. Mammoth hide also
protects the wearer from cold environments as the endure
elements spell.

Rhino Hide Armor:

This +2 hide armor is made from rhinoceros hide. In addition
to granting a +2 enhancement bonus to AC, it has a –1 armor
check penalty and deals an additional 2d6 points of damage
on any successful charge attack made by the wearer, including
a mounted charge.

The fact that Mammoth hide references spirited charge (which requires you to be mounted) suggests that it works when mounted.

I believe one of the rulings was that on a mounted charge both you and your mount are considered to be charging. I can't find a reference to it quickly, though. I don't see any reason it shouldn't apply in the armor's description, so I would likely allow it on charges, mounted charges, and probably aerial dive charges as long as they followed the rules for charging.

Thank you both!

Check the updated version in Adventurer Guide. It works on the first successful charge in a round and calls out to work while mounted.
