Druid / Ranger Animal Shaman / Shapeshifter mix- Damage adds?

[TGMaxMaxer]

Ok. Trying to mix a ranger/druid Shapeshifter/Animal shaman build for the best DPS I can get to, although this is a concept build, so not ever going to be the best DPS. Natural weapon style character and wanna see how to get as much damage as possible.

If I had wanted to fully optimize it I would be lion/saurian, I know. But I was asked to not tweak it to the hilt, now the char is in play, and I should have done more since it's no fun not being able to damage things that were built to take the barb/falchion fighter a while to kill.

I'm trying to at least pull my weight combat wise and be somewhat useful next to a Falchion Fighter and a Barb greataxe wielder. I know i'll never keep up.

Race: Tiefling +Str/Wis -Cha, although i'm keeping the SLA so I can't use the racial for claws. Did take the tail racial.
20 pt buy, normal WBL. 2 Wolf Shaman Druid/ 2 Wild Stalker Shapeshifter Ranger. Druid took Wolf Domain, Imp trip feat and early entry into some ranger spells.

So far, Str 16 Dex 16(level 4) Con 14 Int 10 Wis 16 Cha 6. Char just hit level 5.

Bonus "Legacy" item created by the GM for each character, not to be counted into costs but also not completely under our control for abilities, mine is an amulet in the vein of AoMF and Nat Armor on the same item.(We don't have them yet)

3PP are allowed on a case by case basis, even some 3.5 options (we have a soul muse bard from arcana 3.5)

Will have no problems after level 8/9 keeping up, looking at around 26-28 str by then for 2 combats/day.

1st feat: Natural armor +2(tiefling)
3rd feat: Aspect of the Beast(claws)
5th feat: Power attack, unless someone can suggest better.
7th feat: Shapeshifting Hunter (will be 4/3, is allowed to work with the rage powers that were traded for favored enemy instead, altho at -3 level per the archetype)
9th feat: Shaping Focus (possibly traded for 7th)

Has Claw/Claw/Bite with a trip on the bite for 2 mins/day, claw claw for rest. +2 Str(size)/scent for 5 mins/day 6 round/day of shapeshifter as swift action (+4 str enhance, specifically stacks with polymorphs/wildshape) Will have Rage for 10 rounds/day at lev 8(morale +4str) as free action. Will have wildshape at level 7, canine options. (subpar), and jump straight to huge animal/large magical canine at 11.

Best I can find is claw/claw/bite on a wolverine for a canine type option, until I get magical beasts.

So far, i'm doing 3x1d4+3(+ trip on the bite), +4 with SLA, +6 with shift, at +7/+7/+7 (8 with alter self, 10 with shift)

I have the Bristle spell(APG), which trades Nat armor for hit, and I can cover PA for another +4dam in exchange for -2 AC.

Until level 7-8ish, I'm trying to find a happy medium for some extra damage, as the barb is doing 20-30 a round, (like they do) and the fighter is doing 15-20 easy. My best is 8-10 dam/hit, and the GM is having to use DR to slow them which makes me useless.

Take a closer look at your spell list. Magic Fang works like Magic Weapon which makes your natural attack magical and overcomes damage reduction. Unfortunately, it only works on one attack. Greater Magic Fang can give a +1 to all of your natural attacks. It is a 3rd level Druid spell and your character needs to be a 5th level druid in order to cast it. You might be able to get a wand that casts this spell for you. I don't know the rules for using a wand for a spell you don't have yet.
-OR-
Feat: Eldritch Claws (Combat)
Who needs magic weapons? Eldritch tricks are no match for your bestial ferocity.
Prerequisites: Str 15, natural weapons, base attack bonus +6.
Benefit: You natural weapons are considered both magic and silver for purpose of overcoming damage reduction.
2nd lvl Druid BAB +1, 3rd lvl Ranger BAB +3 = 4
2nd lvl Druid BAB +1, 4th lvl Ranger BAB +4 = 5
2nd lvl Druid BAB +1, 5th lvl Ranger BAB +5 = 6, or

3rd lvl Druid BAB +2, 2nd lvl Ranger BAB +2 = 4
4th lvl Druid BAB +3, 2nd lvl Ranger BAB +2 = 5
4th lvl Druid BAB +3, 3rd lvl Ranger BAB +3 = 6
(5th level Druid BAB is only +3)
or some combination thereof.
-OR -
4 levels of monk will also give you some interesting abilities including a ki pool at the 4th level for making unarmed attacks like magic attacks and overcoming damage reduction as long as you have some ki left in the pool.

[TGMaxMaxer]

I don't have enough levels to mix in another 3/4 BAB class. Plus, in order to use the Ki pool with natural attacks... I would have to have Feral combat training. Natural attacks are separate from Unarmed Strikes unless you use that Feat.

By 8th level (4/4) I'll have Bulls Str, Rage, and Huge size wild shape (Animal Shaman->6th, +4 Shaping Focus=10th level for chosen animal type), not that I expect to get that big with normal space confines, but maybe a time or two. At 9th I'll have Smite evil 1/day as well(planar wild shape) and DR and SR.

The Versatile Weapon spell can help with other special material DR.

It can be cast upon natural weapons.
