One of the most important choices you’ll have to make in Baldur’s Gate 3 is whether or not to allow the Emperor to evolve you. So, here’s what we’d recommend doing in the Larian Studios RPG.
Baldur’s Gate 3 is a massive title with a vast amount of content from different companions to meet, quests to take on, and all kinds of choices to make such as your character’s class and race. Throughout your time in the game, you’ll have to make a lot of decisions that will ultimately impact the world and story.
One of the biggest choices in Baldur’s Gate 3 comes when the Emperor offers to evolve your character and no matter how you respond, this particular conversation will have a huge effect on the rest of the game.

The choice to accept or reject the emperor’s offer rests on you
Is it worth it to let the emperor evolve you in Baldur’s Gate 3?
Yes, you should let the emperor evolve you in Baldur’s Gate 3. Even then, the whole picture is much more complicated than just a Yes or a No.
This is because, if you choose to get evolved then you will gain access to powerful Illithid abilities. However, it comes at a cost where your physical features are changed for the rest of the game. Naturally, the powers are worth and you will get infinitely strong.
However, it is crucial to understand that if you do not let the emperor evolve you then there will be no negative consequences. The emperor will still give you the Astral Tadpole and it will be stored in your inventory.
The emperor will respect your choice in this matter and let you go. Apart from that your physical features will remain unchanged. Therefore, the ultimate choice will come down to what you decide to go with. If you feel that changing your physical features for the power is not worth it then you can always decline the emperor.
