Can combat abilities such as knockdown be combained with charge? If you target a foe and then select knockdow and right after select to charge the target, will the knockdown still fire as it should? Cant test it myself right now and curious about it.

Yes, you can queue up Knockdown as part of the Charge. However, it will use up the only attack you have for that round, so it's not really useful to do, unless you have Dire Charge.

Very good thanks.

if you have the shield feats there is also the shield charge feat that uses the imp. knockdown bonus size modifer

Shield Charge
Type of Feat: General
Prerequisites: Shield Bash, Base Attack Bonus + 3
Specifics: If you hit an opponent with your shield as part of a charge action, in addition to dealing damage normally, you will perform a trip check without provoking an attack of opportunity. If you lose, the defender does not get to try to trip you in return. Size increasing or diminishing effects can affect your trip. (The +4 size bonus from Powerful Charge applies as well as a +4 for Improved Knockdown)
Use: Automatically once a Shield ability such as Shield Bash or Shield Slam hits a target during a charge or Selected

Aye,Shield Charge is great. I use on my main all the time. However this considered a non-shield charger, which I should have pointed out.
