A Firemaking Bow is a firestarter in Survival 303.
The Firemaking Bow is the lowest-tier fire starter. Most players make this due to the fact that its resources are very abundant also makes it quite common. With a fire starter, simply click on any flammable item with the tool equipped. Keep trying until the selected item turns red. If this does not work then it may be fireproofed. To find out, simply take a burning leaf and put it against the item, if it burns then it's not. If it doesn't then it is likely that it is.
