The Polar Bare Club Achievement
The Polar Bare Club10
Be naked, feels like temperature 0° or lower, and 100% wet
To obtain this achievement, it’s best to find a snow biome that is near a body of water. You will also need to make some red tea, which is made at a campfire (that has a cooking pot) using Bottled Water and Chrysanthemums. Once you have your tea, make your way to the snow biome, take off all of your clothes (a cowboy hat can be worn to make your temperature drop faster, but must be taken off to unlock the achievement), jump in the water, then go sit in the shade in the snow.
When your temperature gets down to 5 degrees, take the hat off if you’re wearing one, drink your red tea, and wait until your temperature hits 0. If you are crouching in snow your wetness won’t drop, but you will have to wait for it to get to 100% if you wore a cowboy hat. Once your body temperature hits 0, your wetness is 100% and if you are wearing no form of clothing or armor, the achievement will unlock.
