Where did they move Banishing Arrow to?

I need to farm one. I’ve been stuck at a 14 for a bit. But I’ve checked.

Good question. I've scoured the Quest logs and can't even see it listed as a drop in the past 7 days. Same with Million Storm... wtf do they drop from?

They come from the exploding guys that appear in mining defense and a couple other UQs. since they don't actually drop anything its in the final crystal.
