I found an exploit which lets you spawn an infinite light source which follows you around as Willow. This allows you to keep yourself lit while rowing boats, using tools, or other stuff.
This video should explain it.
Spoiler
IT'S SO HIGH-QUALITY!
Steps to Reproduce
While rowing a boat, equip Willow's Lighter. then make your way to land without stopping the "rowing" process, Once on land, un-equip the lighter and you should get a little fire that follows you around.
