Free Diver - Minecraft

Stay underwater for 2 minutes - 30

First off you will need;

Brewing Stand

Water Bottle

Blaze Powder

Netherwart

Pufferfish

Blaze Powder can be made from Blaze Rod which are dropped by Blazes.

Netherwart can be found in small gardens in Nether Fortress in the Nether.

Pufferfish can only be found while fishing, but are rare.

A Brewing Stand is crafted with 1 Blaze Rod and 3 Cobblestone. Afterwards you need to place a Water Bottle in the Bottom of the Brewing Menu. Then place Blaze Powder in the "Powder Box" (Top Left Bottom with the Blaze Powder Outline). In the Top Box you need to place a Netherwart.

This will brew into an Awkward Potion. Then you need to place a Pufferfish in the Top Box to brew a Potion of Water Breathing (3:00). If you would like you can make it into a Potion of Water Breathing (6:00) by adding Redstone Dust in the Top Box, but it is not needed.

Next you need to go underwater and drink the Potion of Water Breathing, remaining underwater for 2 minutes in total. With the effects of the Potion, you can breath underwater and see much clearer underwater as well.

A Free Diver is someone who dives without Breathing Gear, such as Oxygen Tanks. Staying under water for long times, longer than the average person, up to 15 minutes on one breath.
