So I recently made a character who multiclassed between alchemist and barbarian who focused primarily of two-weapon fighting. I was only planning to go 6 alchemist because I really cherished some of those later rage powers the barbarian gets, such as pounce and come and get me. That left me with 3 discoveries. Spontaneous healing seemed like a good choice when paired with a barbarian with DR. Currently we are level 3, and I am 1 Wild Rager/ 2 Ragechemist (old save dc and plans to pump will).
But then I thought about and saw the vestigial arm discovery, and a lightbulb went off in my head. By level 7, I could have 2 vestigial arms, as well as 2 normal arms, and I can wield 2 Great Axes. I can use one of the great axes in 2 of my hands, and the other great axe in my other 2 hands.
Would this effectively allow me to fight using Two-weapon fighting as well as Two-handed fighting at the same time? If my understanding is correct, then you still only have 1 main hand, and the other 3 are all considered off-hand. So whatever great axe you use in your main hand would use 1.5 Str since you are using it in 2 hands, and your other great axe would use full strength (since it is halved due to off-hand, but adding .5 due to using 2 hands to wield). This changes to 1.5 Str in offhand with the Double Slice Feat. Not only this, but using power attack in this fashion would increase the damage by .5 for both the main and off-hand great axes due to both using 2 hands, but the off-hand great axe would then lose the .5 due to it being in the off-hand. This would effectively make power attack a lot more feasible with two-weapon fighting.
Is my understanding of this interaction correct?
