I've got a robilar knockback dungeoncrasher build and I want to fully understand how does it work.

So, let me get this stright:

Jack the barbarian has a sword on his hand and both feats in the title in addition to combat reflexes. ...and a line of enemies is at each side of him making a kind of hallway. Let's say he intentionally runs through that hallway.

Robilar's Gambit - Benefit:

At the start of your action, you can adopt a fighting stance that exposes you to harm but allows you to take advantage of your opponents' exposed defenses as they reach in to attack you. Anyone who strikes at you gains a +4 bonus on attack rolls and damage rolls against you. In return, they provoke attacks of opportunity from you each time they swing. Resolve your attack of opportunity after your foe's attack.


Karmic Strike - Benefit:

You can make an attack of opportunity against an opponent that hits you in melee. On you action you choose to take a -4 penalty to your Armor Class in exchange for the ability to make an attack of opportunity against any creature that makes a successful melee attack, or melee touch attack against you. The opponent that hits you must be in your threatened area, and this feat does not grant you more attacks of opportunity than you are normally allowed in a round. You specify that you are activating this feat, and the change to Armor Class and your ability to make these special attacks of opportunity last until your next turn


1.- Does he get an AoO from each AoO he generates? Does he get 2?

2.- Does succesful tumble check prevent him from makin one or both of the AoO's against each enemy?

3.- Can he intentionally not use a AoO to make it later against anothe enemy in the "hallway"?

4.- Is there a feat that rewards you if you decide not to spend your AoO but neither spends it?

It's reasonably straightforward.

  • If Jack provokes an attack of opportunity (which means he didn't make a Tumble check to avoid it), then
  • If a guy in the hall chooses to attack Jack (they might not, after seeing the first couple dissolve in a red mist), Jack may choose to attack them, if Jack still has an AoO for the round (Combat Reflexes only gives you up to your DEX bonus).
  • If that guy hits Jack, Jack may choose to attack him again, if jack still has an AoO for the round (Combat Reflexes only gives you up to your DEX bonus).
  • Repeat.

You never have to take an attack of opportunity, either Jack or his opponents.

  1. He gets an attack of opportunity when they swing and when he hits. He gets two only if they hit. He gets one if they try.

  2. You need to make multiple tumble checks, one for each enemy you pass, and can choose to not make a tumble for certain enemies, ensuring that they have an opportunity to attack you.

  3. He can intentionally not use an AoO to save it for later in the same round. Since AoOs are limited to one (or your Dex mod if you have Combat Reflexes), this is a good consideration to make in normal combat as well.

  4. Not that I'm aware of.

One thing to note: Robilar's Gambit requires Combat Reflexes, so any character doing this trick is going to have multiple AoOs. –  DuckTapeAl Jul 6 at 1:20
