Combat Style (Ex)
At 2nd level, a ranger must select one of two combat styles to pursue: archery or two-weapon combat. This choice affects the character’s class features but does not restrict his selection of feats or special abilities in any way.
If the ranger selects archery, he is treated as having the Rapid Shot feat, even if he does not have the normal prerequisites for that feat.
If the ranger selects two-weapon combat, he is treated as having the Two-Weapon Fighting feat, even if he does not have the normal prerequisites for that feat.
The benefits of the ranger’s chosen style apply only when he wears light or no armor. He loses all benefits of his combat style when wearing medium or heavy armor.
