I, uh... hmm. Three is significantly less to work with than four, for terms of ideas. I'll see what I can do, though. I'll definitely have to familiarize myself with the class more.

Hey, uh... if your charisma mod is large enough, wouldn't you be able to take Blossoming Tendril and Ornate Blossom, and use them to extend a budding tentacle from another budding tentacle which extends from another budding tentacle, and so on? And in so doing, essentially use a cheaper form of long tentacle that doesn't accrue an attack penalty?
