Marine Diamond Armor[]
The Marine Diamond armor set is meant to be a sort of "upgrade" of the diamond set, giving the player nearly the same benefits (durability +110).
By equipping the full set, the player will be provided with infinite conduit power effect, giving Water Breathing, Night Vision and Haste. From v1.3, this armor also gives Dolphin's Grace effect.
The advancement "Undrownable" will be unlocked after wearing every armor piece.
Crafting[]
The armor can be crafted using the vanilla recipes, just with marine diamonds.
