How to Start a Fire in DayZ
The quickest way to start an early fire is to create a fireplace by combining 1 short stick and 1 rag and then crafting a hand drill kit by combining 1 piece of bark and 1 short stick. Use the hand drill kit to ignite the fireplace. Bark can be obtained by using a sharp object (knife, hatchet, etc.) on the trunk of a medium or large tree.
If you have an ignition source already, you can place any kindling on the ground and ignite it with the ignition source. This will create a fast-burning fireplace with no fuel. You can add short sticks or firewood to the fireplace to keep it going.
