HP: 300
AC 15 (Natural Armor)
Immunity: Psychic, Poison
Resistance: Blunt, Pierce, Slash from nonmagical weapons
Damage Threshold: 15 (30 under ship)
Damage Threshhold basically means the damage is subtracted by the given amount (ex: 15) or else its reduced to 0. So a guy with an axe doing 12 damage to the ship will fail to affect it since its DR subtracts 15 from the 12 damage, effectively doing 0 damage. And that is assuming the weapon was magica, otherwise resistances will reduce the damage to 6. Adamantine weapon’s ignore both resistances and the damage threshold. Weapons like cannons are not affected by DT either. Spells are though.
