Bleed is confusing (Pathfinder)

[Valdras]

I have been looking at some unarmed feats like Belier's Bite and Boar style which add bleed damage to your unarmed attacks, but it is confusing.

Boar style (http://www.d20pfsrd.com/feats/combat-feats/boar-style-combat-style), says if you hit twice, you can tear flesh and do 2d6 bleed damage.

Bleed (http://www.d20pfsrd.com/gamemastering/conditions#TOC-Bleed) says at the start of the bleeding persons turn, if the bleed is expressed in a dice roll, you re-roll it and they take the damage.

Boar Shred (http://www.d20pfsrd.com/feats/combat-feats/boar-shred-combat), says that if you tear flesh (2d6 bleed damage) then once per round at the start of the the opponent's turn, they take 1d6 bleed damage.

But it says that bleed damage cannot stack, so why the hell would you take Boar Shred and lower your bleed damage by 1d6?

Also, Belier's bite (http://www.d20pfsrd.com/feats/combat-feats/belier-s-bite-combat) makes your unarmed do 1d4 bleed, so that wouldn't work with Boar Style either right?

So does it do damage when you hit them, or does it do damage when its their turn? Or both?

I'm confused, can someone help me? lol

This is a well-known problem and no official clarification seems to be out there yet. The common consensus seems to be that the 2d6 from Boar Style is meant to be a Rend rather than bleed, while Boar Shred applies the actual bleed, but this is a suggested houserule rather than RAW. For them both to be bleeds unfortunately doesn't make much sense.

[Kasbark]

Yeah, it's because Boar Style is supposed to be Rend damage instead of Bleed.

Since there is no errata on this, if you GM plays with Boar Style as bleed damage, don't pick up Boar Shred.

How I read it:
You hit someone straight up, you do damage.
You hit someone twice or more with unarmed and you have Boar Style, you do damage + 2d6 more.
You hit someone twice or more with unarmed and you have Boar Shred, you do damage + 2d6, then every round after that, until the bleeding is stopped, the target of your damage takes an additional 1d6.
If you have the bite, your unarmed strikes would do an additional d4, but if you get the twice hit to proc Boar Style, it would not stack. So more consistent (only have to hit once), but you would have overlap.

I have a coupe theories

Bleed effects do not stack with each other unless they deal different kinds of damage.
What is different types of damage?

Boar Style lets you deal bludgeoning and slashing with the extra ability to tear the flesh for 2d6 bleed damage. Boar Ferocity adds piercing damage with a potential bleed of 1d6 damage.

Now Boar Style would not likely stack with it self because its the same source. However slashing bleed damage from Boar Style could potentially stack with piercing bleed damage from Ferocity.
That is however unlikely, as they most likely mean ability damage/drain vs hit points.

Some suspect that Boar Style was supposed to say rend and not bleed, or that the bleed damage from Boar Style doesn't persist.(its a one time thing). While Ferocity persists normally.

Belier's Bite isn't part of the core rules, I don't even believe its part of Paizo's open gaming content as it isn't on there official SRD. It also predates errata into how bleed damage works. (the no stacking clarification)

The different damages means HP or Ability damage

Plus the Belier's Bite is from this Pathfinder Companion: Cheliax, Empire of Devils (http://paizo.com/products/btpy89ca), so it has to be official surely.

Illithid are official in 3.5 but you shouldn't see their status online because they aren't OGL. My point was to be caution of online content that isn't from the official pathfinder SRD.
