How to create a sword slash particle effect?

Hi, i’m new to particle effects in general and I want to find out how this sword slash particle effect is made.
Pretty much like in these videos:

The “sword slash” effect is shown when the player hits the enemy with the sword (not the animtrails).
If anyone could give me a push in the right direction I would be very grateful!

You will need to learn how to use UE4’s Cascade or Niagara particle systems.

Here you can see a sped up version on how to create something like it: [UE4] -Wild Impact- Luos's A Particle A Day For A Year! 47/356 - SpeedCreate - YouTube

The lazy way would probably be to purchase a pack on the marketplace.

alright, maybe i’ll just use a mesh effect or something
