Level Up (A5E) Enlarging Parasitism thoughts

I was so psyched when I saw the feat name in the preview, now that I’ve got my hands on it I’m a little disappointed that it’s buried three feats into a 5 feat chain.

I feel like it could be combined with ingens survivor and still be a well balanced feat, or remove the feat prerequisites for ingens survivor. I do however understand why the fifth feat is so far down the chain.

I know I’m pretty biased, my favourite spell is enlarge and I’m always hunting for a permanent size increase in games.

What are your thoughts on the feat or feat chain?

Features that change your size can easily get very problematic.

Adding a feat prerequisite push the effect at least 4 levels higher (and higher levels have their own other problems that a GIANT pc might not even matter that much)

If you stick to the examples as written (so it only enlarges Small to Medium and Medium to Large) you can still get to Huge by a simple Enlarge spell. If it could also apply to larger sizes (Galeoni come to mind) you could look down on Cthulhu or "The Kraken" with a combination like this
