The Input System is required but it's only used in the demo scene so you can press buttons and navigate while in Play mode.
The Shader Graph is required for you to be able to edit the shaders.
The sword (made by Unity Technologies) and dummy are included in this asset pack, but read my documentation for a free and easy way to add the character animation.
Easily customizable assets, made with a clear documentation and structure, and made with the Shader Graph and Particle System.
I created the scripts and dummy just to help give context for the effects, not to be game-ready (but, of course, feel free to use them as they are or modify them for your projects). For example, the fire projectile has a script to make some particles disappear more quickly and some more slowly upon impact, to help you undertand how to make the transition from projectile to explosion look aesthetically pleasing.
