CrazyGab's page

here the advices i'll take:
1st Level - Take Barbarian, no archetype
2nd Level - Vivisectionist Alchemist
3rd Level - Alchemist

Discovery - Feral Mutagen

Feats - Power Attack, Extra Discovery (Bleeding Attack)

With Feral Mutagen, you will have 2 1d6 Claws and a 1d8 bite while you are using your Mutagen.

Add Enlarge Person as one of your Extracts.
Take Power Attack.

Use your Rage.

Use a Strength-based Mutagen.

With Mutagen and Rage, you will have a STR of 26.
28 with Enlarge Person, and your claws will move to d8's, your bite to 2d6.
Power Attack will add even more damage.
+1d6 from Sneak Attack (Vivisectionist)
+ bleed damage, which you said you wanted

for natural attacks, you can take all of them in a single full-attack action at your highest attack bonus for primary ones, and at -5 for secondary ones. Things get ugly as you add manufactured weapons (swords, the claw blades, etc).

At present, all of your attacks, CrazyGab, can be primary.
