Helm of the Deep Sea Knight (Patreon)

Wondrous item, uncommon

This patinaed knight's helm has subtle frog-like elements worked into its otherwise functional design. Its narrow visor rests at eye level and is covered by a curved pane of thick glass. The helm weighs 6 pounds and takes 1 minute to don or doff. While wearing this helmet, you can breathe underwater, and you can walk normally on the bottom of any lake, sea, or other body of water. In addition, your weapon attacks suffer none of the penalties of underwater combat.

Valdis stepped through the wound in the wreck's hull, kicking up silt as the last sunlight glinted off the vital helm he wore on his shoulders. It was easy to reach the unquiet dead on land, but at sea, it was far more treacherous.

It was a grim honor to be here. None had walked these halls in decades—even those that tried to claim it never walked its timber planks as its specters once had. He picked through the vessel before coming to the galley. It was there that the ship's sickly, risen dead stood, swaying in the sea's gentle undercurrents like the seaweed outside.

And as the dead's heads creaked and groaned to look at the newcomer, the medium rested his violin against the helm and let the music flow through him and out to soothe the sea around him: the eerie tones of his music carrying through the water like a whale's song for the dead.
