Re: A 1466 Contention
There are two reasons why Snap Kick provides an extra attack on a Charge:
- The extra attacks limitation for Charge attacks lists only general rules cases; the exceptions given (high BAB, TWF) require no feats to obtain, and thus extra attacks from feat(s) aren't "such as" those examples; they're different in kind from those examples.
- Snap Kick is specifically "an ability that changes that". From FEAT DESCRIPTIONS (Player's Handbook, page 89):
Feats exist to provide exceptions to the normal rules, and the Benefit condition ("when you make a melee attack with one or more melee weapons") is satisfied on a Charge.Benefit
What the feat enables the character ("you" in the feat description) to do.
