HOOOOOOOOOOOOOOOLE

Buy these while ult on cd

Buy these when looking to ult soon

If you skipped TP, get it after EE
It's better value than Scourge at that point (unless enemies are spirit heavy)
If you have a lot of money and can't by TP and Scourge, Scourge does do more damage.

You don't need these if you hole them all.

I'm more of a hole guy, myself
