This is the complete diving gear, from the create mod, including the copper backtank, placeable/wearable, the diving helmet, placeable as head block/wearable, and the diving boots.
Copper backtank allows you to use pressurised air with many items, and if you use a diving helmet in the same time, you'll be capable of breathing underwater !!
Boots allow you to run and jump underwater, but when worn, you won't be able anymore to swim, also, mechanical belts won't carry you away anymore ...
Hope you enjoy this design, sorry the copper backtank is really ugly, but understandable at least ...
Tell me what you want to see, and I'll see what I can do.
