Exactly, and if you aren’t destroyed by the vast cosmic energy of an infinity stone, You could end up with a worst fate, Like how The red skull ended up on Vormir guarding the soul stone For about 70 years!
The Reality stone can manipulate reality in any way. @Heartz13 your referring to the MCU version, but i think it already can manipulate reality, it just needs the space stone to have better range and the time stone to make the reality alterations permanent. And btw Wanda Maximoff got her powers 'unlocked' bt the mind stone, so she already possessed those powers before. It was just locked away within her.
And @Mysterylobo The space stone has the ability to manipulate space, space=matter=energy. So yeah, the stone did give carol the powers that are connected to it. And again Pietro and Wanda got their powers mentally unlocked(that means they already had them) before they were experimented on, Hydra found a town in Sokovia (Where Wanda and Pietro lived) that had a host of people who had abnormal genetic make-ups(Probably a hint for Mutants in the MCU).
Mind stone: basically almighty mind which means: psionic energy manipulation, psycho warp, personal domain, godhood basically. All based on the mind since ur the master of it you’ll always be in control
