Ok, a couple questions here:
1) Tumor familiar says that the Alchemist's extracts and mutagens count under the "share spells" feature for the familiar. So, I can detach my hedgehog familiar and pour an Alter Self Extract down his throat, turning him into an orc, gnome, etc? And if I then give him a feral mutagen to drink, he gains the natural attacks, right?
2) It says that familiars use either their Str or Dex bonus for natural attacks. Does this apply to attacks granted to them from a feral mutagen, for example?
3) If yes for 2, is it only a feature of animals/familiars that they can use the better of Str or Dex mods, or is that for everyone? Again, if my alchemist uses a feral mutagen and has better Dex than Str, can he use his Dex mod for those attacks?
Thanks
1) Yes
2) Yes
3) I believe that comes from their size, not type/familiar abilities.Better to take Improved Familiar, get something like an earth mephit, and tear things up.
So if you take the Tumor Familiar discovery you can then apply the Improved Familiar feat? It'd be pretty awesome to have an Imp tumor, hehe.
Re: your answer to number 3--if it's based on size, then how would it work with alter self and feral mutagen? Like, if I just use a feral mutagen on the diminutive sized hedgehog he can use his dex mod with the attacks, but if I alter him into a medium-sized creature and "ferally" mutate him he now has to use his Str mod? Is that right?
Abilities, bonuses, and penalties, based on size, change, with size changes.
So when my small-sized gnome uses reduce person to become tiny-sized, now he can use his Dex mod for his natural attacks instead of his Str Mod? Or do you have to be even smaller?
