There is some confusion on what damage is doubled and what is not doubled on a confirmed critical.
For Example A Level 9 paladin with a Holy Longsword with standard damage does d8+11 and 2d6 Holy. This is base with str and pluses for the magic on the sword.
So if the Paladin does power attack +6 to damage and a smite evil +9 for his level, Inspire Courage (+2 attack/damage), and favored enemy (+1 attack/damage) bonus from the ranger, what damage is doubled on the confirmed Critical?
I assume the +6 from Power attack, and the other +3 points from the misc. bonuses?
If I am correct he rolls a d8+20 twice then adds the +9 for smite evil and 2d6 from the Holy bonus.
Or is he adding the Smite evil bonus twice as well?
Also is there a limit to how many feats you can use in a round, for example the same Paladin has power attack, smite evil (class skill) and cleave, greater cleave. Can he use all of them in a single round?
