Some of these rules reference "virtual" values. A PC's virtual stats are the same as his normal ones, minus the effects of buffs. A monster's virtual level is equal to its CR. To calculate a monster's virtual BAB, treat it as if it had a number of racial HD equal to its CR; for instance a CR 9 Dragon would have +9 BAB, as if it had 9 Dragon HD. A monster with HD equal to double its CR or more increases its virtual BAB by one step (eg. a CR4 Fey with 8HD would have +3 BAB - average rather than poor), while HD triple its CR increases its BAB by two steps. For monsters with class levels, halve the virtual stats gained for nonassociated levels.
Performing a full attack is a standard action. You get one primary attack and a number of secondary attacks based on your BAB. Secondary attacks are made at a nonstacking -5 penalty which can be reduced by Multiattack, like secondary natural attacks. Everyone gets the Two-Weapon Fighting chain for free. Natural weapons are wielded in the same manner as manufactured weapons, but you cannot make claw attacks with an occupied hand.
Standard-action maneuvers replace one primary attack, and full-round-action maneuvers replace a full attack.
When charging, you may end your movement in any square from which you could strike your opponent. Ride-by Attack implies that this was intended.
Whenever you deal hitpoint damage, increase that damage by your virtual BAB. For instance, a 6th-level wizard casting fireball would deal 6d6+3 damage.
You can make a number of attacks of opportunity per round equal to your Int modifier (minimum 1). Combat Reflexes increases this as normal.
Initiative checks are virtual BAB checks, modified by your Dex score.
Ranged precision damage (and the Point Blank Shot feat) functions within the first range increment rather than within 30ft; for every additional range increment reduce the damage dice by one. For instance, an lv3 rogue with a longbow could deal +2d6 sneak attack damage to a target within 100ft, +1d6 sneak attack damage to a target within 200ft, and could not sneak attack enemies further away. Abilities which increase the range at which you can deal precision damage let you ignore one range increment for every 30ft of increase.ClassesSkills
Skill points are not multiplied at lv1. Your maximum rank in any skill is equal to your character level. If you would have a skill as a class skill for any class, you gain Skill Focus in that skill for free. Add the bonus from Skill Focus to your ranks in that skill for meeting prerequisites.
