Highly necessary

If I wrote, "X is necessary for Y," it would mean, "If there is no X, then there is no Y." (requirement) If it is not a requirement, how do you write it?

- "X is a factor that [contributes](/en/contributes) to the establishment of Y." - X is an important element for Y." - "X is [a cause](/en/a%20cause) of Y." None of this feels right. - How about, "X's [contribution](/en/contribution) is high." - Considering that you initially wrote "[need](/en/need) high," maybe the nuance you're trying to express is packed in "[degree](/en/degree) high."
