Increasing Flanking Bonus

[Amphetryon]

DISCLAIMER:
This is mostly a thought experiment, rather than a practical optimization exercise. As such, damage multipliers that would otherwise be key to a flanking build are of secondary importance. The primary concern here is increasing the to-hit bonus from flank, starting at 1st level. Any input on how to achieve that specific goal is welcome.

{table]Kenku Wolf Totem Barbarian 1 | Vexing Flanker |
Barb 1/Ranger 1 | Track, Favored Enemy [pick one] |
Barb 1/Ranger 2 | Adaptive Flanker, Two-Weapon Fighting |
Barb1/Ranger 3| Endurance |
Barb 1/Ranger 4| Riding Dog (tfw) companion |
Barb 1/Ranger 5| Martial Study (Clinging Shadow Strike), Ranger Spells |
Barb 1/Ranger 5/Rogue 1 | SA+1d6 |
Barb 1/Ranger 5/Rogue 2 | Evasion |
Barb 1/Ranger 5/Rogue 3 | SA+2d6, Martial Stance (Island of Blades)|
Barb 1/Ranger 5/Rogue 3/Warblade 1 | Leading the Attack, WRT, Hunter's Sense, Moment of Perfect Mind |[/table]

Currently that makes +8 to hit against flanked opponents, and they can be flanked from odd angles. From here, advance White Raven maneuvers to increase flanking benefits.

Thoughts? Improvements?

[AslanCross]

I know you've already put down human, but the Kenku (MM3) gets AND gives a double flanking bonus from the beginning. (As well as granting +3 bonus when aiding another.)

[boomwolf]

I believe ravinar (race from MM 2 methink) gain a +4 flank instead of +2. (and better "aid another" ability)

[El Dorado]

Swashbucklers gain Improved Flanking at 8th level.

[Amphetryon]

Which would be more advantageous: Kenku or Ravinar, and at a lower LA?

[Gametime]

Can't find the ravinar, but kenku have no level adjustment. They only gain the flanking bonus, though; it doesn't say anything about the ally getting it.

They do give +3 when aiding another, though.

The spell Tactical precision (Bard 2) in the Spc Increase the bonus by 2 when two creature affect by the spell are flanking.

[Runestar]

Does the kenku's flanking bonus stack with vexing flanker or overlap? Both simply say to increase to +4.

[Bibliomancer]

Rilkan (Magic of Incarnum) gets +4 to flanking instead of +2, so you could use that instead of Kenku if you wanted to go into incarnum. However, it might overlap with Vexing flanker (like Kenku) depending on how you read it.

[Soonerdj]

More of a Teammate bonus but I do believe the Nightsong Infiltrator and Nightsong Enforcer each gain bonuses to flanking.

[Amphetryon]

So, assuming the RAW doesn't specify overlap with Vexing Flanker, and enough ranks in UMD to consistently activate a wand with the Bard spell Tactical Precision, we're up to +10 flank bonus to hit.

Is that as high as it gets?

[Soonerdj]

Found the entry, Nightsong Enforcer from Cadv

Flanking Teamwork (Ex): When a nightsong enforcer
of 5th level or higher flanks an opponent, the enforcer
and all other allies who threaten the same opponent gain
a +1 circumstance bonus on their attack rolls (in addition
to the normal flanking bonus, if it applies).

[Thurbane]

If you don't mind taking a -4 penalty to AC, Reckless Offense gives you +2 to hit (in general, not just on flanks).
