Aquatic Gear - Only One Command

Hello again! Today, I've made five items that will help you with all your underwater journeys!

Click here for the command!

Crafting:
Diving Helmet - Iron Helmet + Redstone Lamp + Prismarine Shard
Air Tank - Diamond + Iron Ingot + Bottle
Air Tank (Refill) - Air Tank (Empty) + Bottle
Wet Suit - Iron Chestplate + Prismarine Shard
Wet Pants - Iron Leggings + Prismarine Shard
Flippers - Leather Boots + Prismarine Shard
All recipes are floor crafting!

Tutorial:
First equip your Diving Helmet. It will give you night vision when you are
underwater. You will need an Air Tank to breathe underwater with your
Diving Helmet. Just have a full Air Tank in your inventory to breathe underwater!
Your Air Tank's air capacity will decrease by 25% every two minutes and thirty seconds!
When your Air Tank runs out, you can fill it back up with a bottle. Putting on your Wet Suit
and Wet Pants will increase the speed you swim underwater with your flippers. Flippers
will help you swim faster and more stably, allowing you to run on the bottom of the ocean!
