I want to make a sword have a swinging projectile like Arkhalis, I made the projectile with the help of some older post on this forum. It's swinging, but my problem is, that I have no idea what to change in my code to make the "swing speed" lower (kinda like the "Murasama" from Calamity mod works). I have a gif to explain what I mean a little better (it's a little slow but you can see what I mean).
(I only mean "how many times a second" the damage is dealt, I know how to change the animation speed).
Here's the projectile code:
and here's the weapon code:
Is there a way to edit the code to make it work like that, or do I have to rewrite the whole code?
(I only mean "how many times a second" the damage is dealt, I know how to change the animation speed).
Here's the projectile code:

Vector2 vector14 = projectile.Center + projectile.velocity * 3f; // The following few lines are just to make this projectile 'gorgeous'.
// This adds a white/gray-ish light at the given position.

// the projectile is on the left side of the player while the player is still facing the right.

// that it'll break something for sure.
player.itemTime = 20; // Hmm yeah, not really know what I should explain about this...
player.itemAnimation = 20; // This is actually where we make sure that the player sticks to one animation. If you were to change the animation of your new Arkhalis,
// this is probably where you'd want to do this.
// For this last line you might want to read up what Atan2 actually does, but you might be able to guess what this does based on the 'itemRotation' name.
// This doesn't really do anything for the actual AI of the projectile, but makes sure that the 'item' is facing the correct way (although the player is not actually
// holding anything :p).
