You can unlock special particle effects from events and in /perks to show off your style... well, in style! Swirling effects around you, sparkling trails following you, or even explosions whenever you teleport.
You can also get custom particle effects on the store or in /perks and come up with your own styles. (Limit of 5 effects per custom particle).
Do particles give me any powers?
No, they are purely visual and just for fun.
How do I turn particles off?
Use the /pp menu to disable or change your effects. You can also do /pp toggle to disable seeing others' particles if they get annoying
What do the particles look like?
You can see a list of some of the options here. When you make a custom one, you pick from the list of premade animations to mix and match your own idea!
