So how do we use these sparklers...?

Got the sparklers, but now I can't seem to figure out how to use them?

Any suggestions?

Good work BTW SE.

They are in your consumables pack. Open up your pack, select it, then sub-target yourself.

if you are asking for how to literally use them, press U on the keyboard. Then simply scroll down and find it, click on it, and bam!

Well I never... Thanks!

Great effect on them aswell. Amazing.
