A log is a renewable material required in various Carpentry recipes.
Logs are incredibly heavy, with a weight of 9. The player can combine logs using rope to reduce the weight to just a third. Up to 4 logs can be combined in this way.
Using a saw, 1 log can be converted into 3 wooden planks, which are incredibly important in carpentry. Logs can also be used to create log walls, which are slightly stronger than the variety crafted using planks, and with the added benefit of requiring neither nails nor a saw to craft.
Logs are a valuable fuel source for campfires and antique stoves, as they last 4 hours and are sustainable.
A log has a secondary purpose of crushing watermelons, though it is not as effective as slicing it with a saw.
The log is the resulting product when a tree is chopped down, which is done most effectively with an axe. It can be found while foraging and inside log stacks.
