you can use 1-2 on your Way to clear Elevators -> Either refill when you have 3/5 Bonfires+Active Elevators -> OR -> Burn 4x at Fume Knights Arena (3 at least)

When I was new to the DLC, I wasted alot by tossing alluring Skulls beneath, trigger the Explosion (it gives I-Frames and Stuns all Enemys ~5 seconds) and go for All-In-Lever-Pull.
But I would rather use them exclusively around "Animated Armor" Enemy Types (The goofy moving Archer/Fire Guys), cause it makes them ressurrect themselves - And of Course around Fume Knights Arena!
Youtube has pretty good shorts about Locations/Runthroughs/Techniques for the DLC
