The infernal dwarves travel across the Underland seas and the Sıfırda Rivers atop vessels of wicked construction, formed from the carcasses of long dead megafauna and powered by their bound souls. Creatures that are not Evil have disadvantage on checks made to pilot these unholy boats, and while in contact with it a Good creature is rattled (though anyone that is not Evil feels terrible discomfort while riding on it). Taking the boat onto the surface is a risky endeavor as well; on initiative count 20 each round it is in sunlight, the Zustramet logboat takes 25 radiant damage.
Despite its drawbacks however, creatures sailing the vessel through Underland have no random encounters against other creatures and if left to sail itself automatically heads towards the Kingdom of Zustramet. Furthermore the Zustramet logboat is able to utilize the Sıfırda Rivers, taking them when available and reducing the distance the party must travel to reach the Kingdom of Zustramet by half.
