Cavalier

[Sarrah]

A Cavalier "Spirited Charges" (3x damage with a lance) someone. If later in the same round another person provokes an attack of opportunity from the Cavalier, does the Cavalier's "Spirited Charge" bonus apply to the attack of opportunity? ... Cavalier's Charge (+4 to hit) bonus apply to the attack of opportunity?

Basically, do bonuses that help with attacks last until the beginning of the character's next turn?

[Bad Sintax]

No. If that were the case, it would say "This lasts for 1 round." The extra damage from the charge and the +4 to attack is just on the single charge attack.

Why would you get a bonus from charging when you weren't charging?

[Sarrah]

When there is a penalty to charging (+2 to hit, -2 to AC), it lasts the whole round (-2 to AC). I cannot find where it says the +2 to hit does not last the entire round. I will keep looking for it.

[Imbicatus]

No, it applies only during the charge. In FAQ, [see what I did there? :)] You only get the bonus on your first attack in a charge if you have pounce.

[Rub-Eta]

It would be specifically noted if it lasted longer than one attack.
