Purifying Light > Dark Flare > Javelin > Toppling Charge > Crescent Sweeps ULT > Jabs/Charge til dead.
I use that combo when I'm at range and close the gap.
In melee, I use PL > ULT > jabs until I can get them near half or less, hoping for those huge burning light procs, then: Javelin > Toppling Charge > Sweeps to finish.
Sometimes if I feel like I can't get the damage I want off of PL that day, I'll switch it off and move to Jesus Beam. I use one or the other for an execute. It just depends.
I think Javelin into Toppling Charge into X ability is a great way to hit 3 things at once and force the opponent to take it, haha. That is, to say, the whispers I get are very salty when I terrorize someone with that combo.
