I mean....I like more power and skills. But I am really struggling with the idea that in order to do this I am going to need to allow multiple vile little creatures swimming in my brain. I am not even a big RPer, I lean more to the combat strategy and exploration side of things. And even for me this is difficult so swallow (or in this case, drill another eye hole)
In my opinion the idea of putting more things in your head sounds a bit silly. I think it would seem more reasonable if instead of adopting and welcoming them to your brain, you still killed the other tadpoles but were given the option for your own tadpole to somehow absorbe their essence or something.
