How to make the same bullet pattern from the video below?

Hello, so it's me again with something based about my last topic, here i just want to replicate the function of a game that i recorded, mainly the mechanic of making the spear rotate and face towards the player really smoothly.

I don't know how do i replicate it in the way that after the rotation slows down, it will perfectly rotate-facing the players acquired position. Yes it won't predict or face it all time, will just get the player X and Y cordinates when the spear is created, stops rotating and launch it.

Just see the video below, it's happens at the 3rd and 5rd attack patterns.

There’s a “rotate toward position” action that lets you smoothly rotate to face a location.

Oh, i forgot about that expression, helped me a lot, gonna try it and see if it works, really thank you!

Actually, can you explain me how to do that smoothly? Because i don't know how to use lerp if that's necessary, and i don't know either a good way to do it.
