Imagination Manipulation

So, I have an OC named Powerstrike who wields the Great Force via imagination manipulation. His primary weaknesses are:

Health: Can't use his powers if he's not in his peak mental state like being exhausted or sick. Can and will cause strain.

Power limitations: can absorb/copy 10% of powers for 10 minutes during a 10-second timeframe. A full 10 seconds lets him permanently keep the power at its original strength.

However, I'm having trouble choosing which superpower manipulation works best, superpower manipulation or power warping.

It’s a normal night like any other and you get in bed to go to sleep but as soon as you close your eyes you see him a giant figure his body looks like tree bark his eyes made of fire you find yourself floating in a strange green-blue smog you try to wake up but you can’t your stuck suddenly The being speaks and says “I am 𝕸𝖆𝖑𝖍𝖆𝖈𝖆 sigh this contract and gain unfathomable power.

If this entity made you a deal would you take it?

These are the terms of the contract are: You are under obligation to obey Malhaca becoming his herald, signing this contract you agree that you must answer to Malhaca and Malhaca alone, (if you sign the contract it is impossible to break it) in exchange for servitude he will grant you a portion of his power giving you absolute power over dreams, and the minds of others as well as the power to manipulate imagination and fictional lordship. And you will also become immortal would you except this deal? Or would you try to escape? Who knows what he will do to you if you refuse.

I think imagination manifestation is my favourite because of the near limitless things you can do with it. Like I’d probably create a whole friend group of people who have powers and then we can be like the real life avengers or something like that 😂👌
