So, I've found Shifter (more specifically Wild Effigy archetype) to be incredibly strong if built right, but after attempting to make the build I found that A LOT of things just don't work.

So here are my findings

I've done some extensive testing on Wolverine shifter, here are my findings:

WORKS

• Fang of Malice (+2 AC when raging)
• Demonic Resentment (+1 AB/damage when raging)
• Promise of Power (self-trigger Rage as free action)
• Stalwart, Improved Stalwart (up to +10 DR/-)
• Close to the Abyss (Magical Gore natural attack)
• Call to Violence (+2 AB/dmg)
• Reckless Stance (+6 AB, -6 AC)
• Guarded Stance (+6 AC)
• Wrecking Blows (+3+CON damage)
• Master Shapeshifter (+4 STR/DEX/CON)

KINDA WORKS

• Beast Totem (+5 Nat AC) - only works with Wolverine rage, not external
• Limitless Rage - Works for Wolverine Rage but you need external rage to pick the Mythic Ability
• Powerful Stance - no damage is added unless you take different rage class, but once you do it works with Wolverine Rage too

DOESN'T WORK

• Level 15 shifter fatigue immunity
• Fiend Totem - horns are displayed, no natural attack
• Mangling Frenzy - No DR is added
• Lethal Stance - no AB is added
• Animal Fury - No bite attack

WTF

• Skald's Inspire Rage with Powerful Stance adds damage boost equal to Shifter CL

Note on Rage Power stances - they don't seem to care about your Shifter level at all, and will grant full bonuses. So if you take Guarded Stance at level 8 you'll just get +6 Dodge AC
