This thick, colorless spread makes ships and watertight containers less susceptible to damage and leaks. One drum of sovereign sealant is sufficient to treat a boat or container of Huge size, or two hull sections of a larger craft.
A treated wooden item gains +2 hardness and is completely waterproof. A ship treated with sovereign sealant can lose one more hull section than normal before sinking.
Prerequisites: Craft Wondrous Item, minor creation.
Cost to Create: 4,000 gp, 320 XP, 8 days.
