I was messing around in Creative, when I realized that Orbit causes insane levels of lag when enough of them are spawned.

A very quick way to do this is to cast the spell:

Projectile -> Burst -> AOE -> AOE -> Sensitive -> Orbit -> Pierce

Doing so summons an unholy amount of of Orbit entities, causing massive frame drops. If performance improvements are too difficult, I suggest adding a check that begins removing the projectiles under a certain threshold. Maybe add a silly particle effect when the projectiles turn "Unstable"

It seems like Burst in general causes a lot of lag as well, after trying it with Break
