I am sad that we have to tell people that putting additional illithid tadpoles in your brain is probably a bad idea. Then again we have instructions on packs of toothpicks.
I would choose to see this as an option for people who choose "power at any cost" - this is pure Lord Voldemort and Horcruxes. You gain power at the expense of yourself.
Remember, Astarion WANTS the tadpole but wants to control it because it "frees" him to some extent. So this is related to that.
What is incredible is that this is likely just a tiny part of the game that incorporates a path you can go down and its supports how much you want to descend into iniquity and self destruction.
Bravo!
I don't think people needed a warning to understand that tadpoles are bad in the EA, but now you see a whole screen and upgrade tree related to them and nothing that actually encurages you to ignore a system of the game that seems to be a large part of your potential character progression.
Everything up to that point is about how having a tadpole in your head is suuuuper bad.
Look, I get it, there are gamers out there that don't have two braincells to rub together and have zero awareness and for THOSE people they are going to just roll their faces across the keyboard in response to everything, die horribly 500 times and quit the game. All of this on story mode btw.
You will NEVER be able to dumb the game down enough to make it safe for them.
The average gamer will get tadpole = bad and won't mess with it.
Then you get the super gamers, the roleplayers, and the smart lasses and laddies who are going to have a lot of fun with this in various ways.
