So I'm working on building Doctor Octopus and looking to add tentacle attacks (without using a cheesy synthesist summoner). A Kraken Caller Druid gets two at 4th level in their natural form (and more later). I was thinking about adding a 1 level dip in Shifter and make use of their Alternate Natural Attacks to turn their two claw attacks into two tentacle attacks, but I'm unsure if I can.
Here is the Alternate Natural Attacks text:
A shifter can draw on her chosen animal aspect to transform her hands into deadly weapons, as represented by the shifter’s claws class feature, but not every animal has prominent claws. The following list provides alternate natural attacks for the shifter claws class feature. Each time the shifter activates her shifter’s claws ability in her natural form, she can manifest one of the alternate natural attacks listed below for any of her chosen aspects, or those that relate to her archetype. Each alternate natural attack replaces one of the shifter’s claw attacks. The shifter can gain up to two different alternate natural attacks with this method. These alternate natural attacks modify only the damage type of the shifter’s natural attacks and otherwise function exactly as the shifter claws class feature.
The bolded part is the part that's tripping me up. I, of course, want to go with an Octopus aspect, which has these natural attacks listed:
Octopus: Bite (B, P, S), tentacle (B).
Am I able to turn my two claw attacks into two tentacle attacks? Or would I have to turn one claw into a bite and one into a tentacle?
Also, if I turn one or more claw attacks into tentacles, do my whole arms become tentacles thereby making them unusable for other things?
And can I take Alternate Natural Attacks with the Adaptive Shifter archetype?
Finally, am I correct that when using the Kraken Caller's Wild Shape ability to add tentacles while in my natural form I can also stack on Shifter's claws?
