When I shoot the 11 dynamites with a flammable arrow, the dynamites disappear.

I would expect the flammable arrows light the dynamite.
I hope the pits slow down that skeletal juggernaut…
If I find a RC controller, I would make radio-activated pipe bomb and put the pipe bomb on top of the 11 dynamites.
Apparently, the flammable arrows just do nothing. After I activate the flammable arrow, when I shoot it at a dandelion, it doesn’t make a fire.
The flammable arrows are made from lamp oil(50), metal broadhead arrow(5), and rag.
I am playing 0.D.
