Thank you all for the advice, and to all the people saying my dm is a jerk if he messes with my wish, i just want to say he loves roleplaying and this wish is being granted by a very chaotic being (idk what it actually is) so its not that the dm wants to ruin my game, but as per the creatures...
My dm is a totally fair person, but he does love ruining wishes if he spots a chance to. My current best idea is "i wish to be physically stronger" but i feel like that could increase my dextarity or constitution.
