Is Hex worth it at high levels?

[KorvinStarmast]

It's a decent pick for the Fey-Touched feat. Doesn't use up a spell slot and can work pretty nicely with non-Warlock builds. The damage isn't game-changing especially at high levels but the ability check hit is pretty nice for a grappler or a few other circumstances.

That is where my Rune Knight got it: Fey Touched. Also, the misty step once per LR is good for certain pursuit and escape situations.
