This was initiated by my not being able to use Sparkle Powder at Ajaya. Alternatively, if lagging is the problem, why not implement a less laggy animation should a certain threshold be crossed? Or say, add another sprinkle option that lets you use only one pinch and limit the effect to, say, X random people within a certain distance to you (because you would throw powder in the air and not just drop it over your head)?
But yeah, used the powder for the first time a few minutes ago. It's awesome :D
