Feats of Opportunity
Thunk! Thunk! Do year hear that? It’s the sound of opportunity knocking: some unlucky hobgoblin flat on his back. That’s right, in Pathfinder, opportunity attacks the meek as well as awaits those bold enough to take advantage of it. To that end, I offer you the unique chance to make the fullest use of your opportunities with these brand new feats, which, if you haven’t guessed by now (and thus probably never will), all have to do with attacks of opportunity.
Advantageous Opportunist [Combat]
You are adept at exploiting the weaknesses of your foes and can place your blade in the most effective spots when your opponents turn their back.
Prerequisite: Base attack bonus +1.
Benefit: You deal additional damage and strike more accurately whenever you make an attack of opportunity. You gain a +1 bonus to all attack and damage rolls made as part of an attack of opportunity. These bonuses increases by an additional +1 for every 4 points of base attack bonus you possess (to a maximum of +6 at base attack bonus +20).
Expert Opportunist [Combat]
You are well practiced in the art of attacking those who foolishly leave themselves open to you, and have learned to take advantage of all the opportunities around you.
Prerequisite: Base attack bonus +1.
Benefit: You may make an additional attack of opportunity each round.
Special: You can gain this feat multiple times. Its effects stack.
Exposing Strike [Combat]
When your foes leave themselves open, you are able to attack them in such a way as to put them completely off balance, leaving them vulnerable to further attacks.
Prerequisite: Base attack bonus +1.
Benefit: Whenever you successfully deal damage to a creature with an attack of opportunity, that creature is knocked off balance, suffering a -2 penalty to AC and to all attack rolls made until the beginning of their next turn. Multiple instances of this ability do not stack.
Master Opportunist [Combat]
You are so practiced in taking advantage of the weaknesses of others that you can attack foes who expose themselves with blinding speed.
Prerequisite: Combat Reflexes or Expert Opportunist, base attack bonus +6.
Benefit: Whenever a creature provokes an attack of opportunity, you may make an additional attack of opportunity against that creature, assuming that you have enough remaining attacks of opportunity available to do so this round.
Special: You can take feat again when your base attack bonus reaches +11 and +16. Its effects stack.
Supreme Opportunist [Combat]
You have completely mastered the art of opportunistic combat, even surpassing the practiced defenses of so-called experts.
Prerequisite: Combat Reflexes or Expert Opportunist, base attack bonus +6.
Benefit: Whenever a creature performs a combat maneuver, you may make an attack of opportunity against that creature, even if they would not normally provoke an attack of opportunity for doing so (such as if they had the Improved Disarm feat, for example), albeit with a -5 penalty.
