Special Traits

  • Amphibious. The sea drake can breathe air and water.
  • Siege Monster. The sea drake deals double damage to objects and structures.


  • Multiattack. The sea drake makes one bite attack and one tail attack.
  • Bite. Melee Weapon Attack: +6 to hit, 10 ft. reach, one target. Hit: 22 (3d10 + 6) piercing damage.
  • Tail. Melee Weapon Attack: +6 to hit, 10 ft. reach, one target. Hit: 17 (3d8 + 6) bludgeoning damage.
  • Ball Lightning Breath (Recharges 5-6). The sea drake can breathe a ball of chain lightning as per the chain lightning spell except that each creature struck must succeed a DC 15 Dexterity saving throw or take 3d6 lightning damage. If it wishes, it can exhale tiny drifting motes of crackling electricity that deal no damage but rather act as dancing lights.
  • Capsize. The sea drake is skilled at ramming its bulk into the side of watercraft up to 20 feet long and 10 feet wide, whether swooping from above or swimming up from below. As an action, it can make a Strength (Athletics) check against every creature on board the boat, seeking to force creatures prone or force them overboard. It makes a single check and compares the result to all creatures on board. At the GM’s option, if it successfully Shoves all creatures on board, the entire boat capsizes.


  • Draconic Surge (3/Day). The sea drake can take an additional Dash action on its turn.


While obviously the product of draconic inbreeding, the heritage of sea drakes is less clear than that of other lesser dragons like wyverns and the like. Though among the strongest of such “false dragons,” sea drakes lack the mental acuity of their true dragon forebears, though they do possess a certain brutal cunning. Although amphibious, sea drakes spend the majority of their time in shallow coastal waters. Sea drakes are up to 14 feet long from their noses to the tips of their powerful tails. They weigh 2,000 pounds.

Rampage. The most solitary of all drakes, sea drakes prefer to hunt alone. Occasionally, however, they band together in packs to hunt larger prey. Such rampages can be a significant danger to coastal shipping.
