I was talking with a friend the other day, and I came across the idea of playing a polymorph-focused caster.
Now, with the many supplements that Paizo has published, nearly every type and major subtype of monsters have been covered, there are a few that remain.
Aberrations: Highly varied and difficult to properly balance, but such was the polymorph school in general, Similarly to Undead anatomy, this spell seems quite possible.
Construct: Also quite difficult, probably needs to be modeled after Plant Shape, due to similar immunities, with only the highest level of the spell granting magic immunity, if at all.
Fey: See Abberation, probably isn't necessary due to most fey being non-combatants.
Ooze: Admittedly, the Cave Druid archetype already does this, kinda. Still, I'd like to see a full version that is actually built to mimic oozes.
Lastly, Outsiders: This creature type is so big and vast that I don't see any way to do justice to the various types of outsiders other than to do seperate spell sets for each of the alignments, catching entire major species as well as fringe outliers.
Perhaps we could also do with a dragon polymorph that handles linnorms and other dragons that exist slightly beyond the bounds of Form of the Dragon.
Anyone?
In case of dragons it would be simple: just add the linnorms (and other reatures of dragon type) to the list of shapes allowed, beyond chromatic and metalic dragons.
I think it would take a bit more than just a simple addition of the other types, because a lot of other types of dragons have different abilities compared to their counterparts. Example: Drakes, whom don't have a true breath weapon per se, but have their spittle ability. Also consider that some linnorms and other dragons, including primal and imperial dragons, have differing sets of breath weapons. As the rules stand now, you can't breath a cone of lightning, despite taiga linnorms, cloud dragons, and sky dragons having them. And what about poisonous dragons, like the wyvern?
The way I see it, its a bit too late to rewrite an entire spell set just to include more types of dragons in the same spell, which is why I reccomend that dragons that don't follow the typical pattern of true dragons in terms of progression and abilities ought to have their own spell.
Any thoughts on the other creature types?
