Nautilus Diver
by Qady
Nautilus Diver is a NeoForge equipment mod that adds a helmet giving the wearer unlimited underwater breathing.
What it does
The Nautilus Helmet is crafted from two Nautilus Shells and two hearts of the sea, and it grants an infinite water breathing effect while worn, unlike the turtle shell. Only NeoForge files are published, for 1.21.1, and the license is MIT, so the source code is open source. Client and server both need the mod.
