Various Bullrush Questions

[TGMaxMaxer]

Ok, several questions here, all important since they all apply to a character I am building. I will include full feat text for these, to help with all the hunting, copied from the pdfs or PRD.

Does the bonus to Bullrush CMBs from Imp Bullrush and Gr Bullrush get factored in while using Shield Slam?

Shield Slam:

In the right position, your shield can be used to send opponents flying.
Prerequisites: Improved Shield Bash, Shield Proficiency, Two-Weapon Fighting, base attack bonus +6.
Benefit: Any opponents hit by your shield bash are also hit with a free bull rush attack, substituting your attack roll for the combat maneuver check (see Combat). This bull rush does not provoke an attack of opportunity. Opponents who cannot move back due to a wall or other surface are knocked prone after moving the maximum possible distance. You may choose to move with your target if you are able to take a 5-foot step or to spend an action to move this turn.

Does Gr Bullrush trump the clause in Shield Slam, thereby granting AoO to enemies moved by the bullrush? That is the specific benefit of the feat, to cause movement from a bullrush to provoke.

Greater Bullrush:

Your bull rush attacks throw enemies off balance.
Prerequisites: Improved Bull Rush, Power Attack, base attack bonus +6, Str 13.
Benefit: You receive a +2 bonus on checks made to bull rush a foe. This bonus stacks with the bonus granted by Improved Bull Rush. Whenever you bull rush an opponent, his movement provokes attacks of opportunity from all of your allies (but not you).
Normal: Creatures moved by bull rush do not provoke attacks of opportunity.

If you have a feat that grants a swift action on the completion of a successful attack, can it be performed during an AoO? Such as making a Shield Bash with a Spiked(or normal) shield using Shield Slam as the AoO, thus proc'ing Spiked Destroyer?

Spiked Destroyer:

You can attack with your armor spikes while using bull rush or overrun.
Prerequisites: Worshiper of Gorum, proficient in spiked armor.
Benefit: When you succeed at a bull rush or overrun combat maneuver, you may automatically make an attack roll with your armor spikes against the target of the maneuver as a swift action. This attack is made using your highest attack bonus

Since a spiked shield is a weapon in and of itself, can a critical hit be used to proc Bashing Finish?

Bashing Finish:

You follow a powerful blow from your weapon with an opportunistic bash from your shield.
Prerequisites: Improved Shield Bash, Shield Master, Two-Weapon Fighting, base attack bonus +11.
Benefit: Whenever you score a critical hit with a melee weapon, you can make a shield bash attack against the same target using the same bonus as a free action.

Hello. I'll give some help, as much as I can. As these aren't really Pathfinder Society specific questions, this thread may be moved to the general Rules Questions boards.

Yes, I believe so. The attempt is separate from the attack, so you're essentially doing the bash, then getting a free Bull Rush.

The verbiage on those feats are a little confusing, but the AoO for the Shield Slam Bull Rush mentioned above is towards the attacker, not the victim. If the attacker didn't have the Improved Bull Rush feat, it provokes to do a Bull Rush. Shield Slam negates that AoO when done in this fashion.

The AoOs in Greater Bullrush means that the attackers allies (but not the attacker) get AoOs against the victim for movement caused by the Bull Rush..

No. Swift Actions can only be taken on your turn. If it were an Immediate Action, then it might work.

This isn’t really a PFS related question (other than the fact it may be for a PFS character). But here’s an answer anyways.

Improved Bull Rush and Greater Bull rush apply their bonuses to all Bull Rush attacks. So if the Improved Shield Bash grants a free bull rush, then yes, you’d get the +4 to your free Bull Rush, and you’d cause them to provoke AoO’s.

Swift actions can only be taken on your turn, so no, you could not use the Spiked Destroyer feat on an AoO.

Expect table variation with Bashing Finish. Some GM’s may feel that using the spiked shield to trigger an additional spiked shield attack breaks the spirit of the feat. However by the way the feat and the way Shield Spikes are written, I would say it should work ok.

PRD wrote:

Shield Spikes: These spikes turn a shield into a martial piercing weapon and increase the damage dealt by a shield bash as if the shield were designed for a creature one size category larger than you (see “spiked shields” on Table: Weapons). You can't put spikes on a buckler or a tower shield. Otherwise, attacking with a spiked shield is like making a shield bash attack.

An enhancement bonus on a spiked shield does not improve the effectiveness of a shield bash made with it, but a spiked shield can be made into a magic weapon in its own right.

Thx for the responses, I was already factoring in the Imp Bull rush feat so hadn't even looked at the Shield Bash reference meaning for the wielder.

I was thinking that swift being a 1/round thing wouldn't work on AoOs... just wanted to be sure in case it did, (secretly hoping for that free swing in addition to my AoO).

Bashing Finish shouldn't come up much anyways Spiked shield is 20 x2, and not plannin on keen or imp crit on that weapon, so not a big concern, again just clarifying my own interpretation.

Love this forum thing, less than a day turnaround on (usually) well reasoned answers.
