Apparently there’s this glitch on solstice that DRASTICLY reduces the amount of grinding you need to do to get the Kindling!
You just need to do all the quest on one character,
Transfer your other characters armor over to the maxed out character, and just apply the silver ash there. The only thing you’ll miss out on is the little glow. But tbh, it doesn’t matter.
I recommend you take full advantage of this.
This is very helpful as I dreaded doing the hand canon and shotgun kills on all 3 characters.
