There's a bug, if the arrow kills in one hit, the explosion will not trigger, could anyone fix that?

Also can someone make a mod that enables flame enchanted bows to spread fire, or make an arrow that can spread fire?

does it work in a crafting table and fletching table

Small but effective! This looks just innocuous enough for me to be able to stick it into custom maps and other heavily modified worlds without breaking stuff.

Do standard spectral arrows also explode, if crafted with glowstone dust? If so, either renaming them and having it only trigger with the renamed arrows, or removing the crafting recipe for regular spectral arrows with glowstone dust, would work.

Very good!! :)

I guess theses TNT arrows also works from a dispenser. :p

Pretty expensive for survival :(
What about just 4 gunpowder per arrow? Like around it in a ring?

Thank you for this, you might want to add the recipe in the description.

For any one wondering it's:
1x Arrow + 1 TNT
