Canny Tumble + Disorienting Maneuver

[Richard McGuffin]

I just want to make sure I understand this correctly. If you use acrobatics to move through an opponents space do these two feats stack? So you could gain a +4 to hit on the first attack or does the circumstance bonus not stack?

Canny Tumble ACG
Prerequisite(s): Dodge, Mobility, Acrobatics 5 ranks.

Benefit: When you use Acrobatics to move through an opponent's threatened area or space without provoking an attack of opportunity from that opponent, you gain a +2 circumstance bonus on your next melee attack roll against that opponent, as long as you make that attack before the start of your next turn.

Disorienting Maneuver UC
Prerequisites: Dodge, Acrobatics 5 ranks.

Benefit: If you successfully use Acrobatics to tumble through an opponent’s space, you gain a +2 circumstance bonus on attack rolls against that opponent until the start of your next turn. If you choose to make a trip attempt against that opponent, you gain a +4 circumstance bonus on your combat maneuver check. This bonus on trip also lasts until the start of your next turn.

Sidenote: I find it odd that the newer feat has three strikes against it. It has stronger prerequisites, works only on the first attack and doesn't give a bonus to a combat maneuver.

They don't stack as they are both circumstance bonuses.

Good question. If we look to the Dungeon Master's Guide we find that circumstance bonuses don't stack if they arise from essentially the same source.

So, do these two bonuses arise from essentially the same source? I think they might.

[Richard McGuffin]

Ok, they don't stack. Thank you.

Also the only advantage of Canny Tumble over Disorienting Maneuver is that you can use it through a threatened area not necessarily through the opponent's space right?

[Lakesidefantasy]

Yes, which reduces the DC by 5 (relative to tumbling through their space).

Also, if you fail the acrobatics check to tumble through a foe's threatened area you simply suffer an attack of opportunity but you continue to tumble through. On the other hand, if you fail to tumble through a foe's space you are stopped and suffer an attack.

[Richard McGuffin]

Cool thanks guys! Just wanted to clear that up in case of pushback.

Update: A new advantage of Canny Tumble is that the target loses its Dexterity bonus to AC, making this feat especially handy to anyone who sneak attacks.

And they do stack. Circumstance bonuses stack unless from the same source. Two separate feats are separate sources.
