How to Catch the Sea Dragon in The Seven Deadly Sins: Origin

To catch the Sea Dragon in The Seven Deadly Sins: Origin, craft or purchase Gold Potions and intercept the creature at the lowest point of its coastal flight patrol. The Sea Dragon is an exclusive taming encounter that rejects standard lower-tier potions, requiring top-grade consumables to unlock the game's first companion capable of both aerial flight and deep-water diving.

Why the Sea Dragon Matters

Terrain exploration across Britannia often requires juggling specialized companions to bypass natural barriers. Standard flyers cannot submerge to explore sunken ruins, while dedicated aquatic mounts cannot scale coastal cliffs once you surface.

The Sea Dragon solves this friction by serving as a dual-environment mount:

• Mid-Air Gliding: Launch directly off seaside cliffs to ride updrafts across coastal islands.
• Seamless Diving: Plunge directly into open water without dismounting to explore submerged caverns and seabed nodes.
• Slot Efficiency: Consolidates flight and aquatic navigation into a single companion slot, eliminating pet swapping during exploration runs.

Preparation and Gold Potion Requirements

The Sea Dragon cannot be captured with green or blue taming elixirs. Approaching the beast without the correct consumable prevents the taming prompt from activating, leaving your character vulnerable to aggro in open water.

Before heading to coastal waters, prepare the following:

• Stock Reserve Potions: Bring three to five Gold Potions. High-tier taming carries variance, and having a reserve prevents wasting an encounter if an attempt fails or an aggro reset occurs.
• Bind to Quick Access: Place Gold Potions directly onto your active action belt so you can trigger the prompt immediately upon entering interaction range.
• Check Surroundings: Survey nearby shoreline threats to avoid entering combat during the channeling window.

How to Locate and Intercept the Sea Dragon

The Sea Dragon patrols open coastal reefs and offshore waters along a repeating circular flight loop. It alternates between soaring at high altitudes and descending close to the surface of the water.

1. Take High Ground: Scout from a seaside cliff overlooking the patrol loop. Track the creature's serpentine silhouette and aquatic fins to identify where it reaches the bottom of its flight path.
2. Clear Local Hostiles: Eliminate nearby coastal predators before the Sea Dragon approaches. Taking damage while taming cancels the interaction.
3. Wait for Low Descent: Do not pursue the creature while it climbs into high airspace. Wait until it glides downward near sea level.
4. Close the Distance: Dash or glide toward the creature as it skims the water surface to trigger the capture radius.
5. Channel the Potion: Activate your Gold Potion the moment the interaction prompt appears, remaining still until the capture confirmation registers.

If the Sea Dragon enters combat mode before you trigger the potion, retreat to the shoreline immediately to drop aggro. Attempting to force an interaction while taking damage will interrupt the channeling process and waste your positioning window.

Traversal Capabilities Compared

The Sea Dragon's primary value lies in its hybrid flexibility compared to single-purpose mounts:

Prioritize using Gold Potions on the Sea Dragon over standard single-purpose creatures to gain full access to Britannia's aerial routes and submerged exploration zones with a single companion.
