I have a party of with 3 Mounted members, they're saying that when they charge with their lance they hit for +28 (x3) for every time they preform a spirited charge with a Power attack + Smite.
This is the only rule I found that has anything to do with multiplying damage aside from criticals, it's really hard to set up a Campaign if they can literally hit for a minimum of 93 dmg when charging. Is there something I'm misunderstanding? The Lance says it doubles your damage already, spirited charge makes it 3x.

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.
Do I just have to make situations to force them off their mounts? Because dear god.
