There are currently 18 commendations for you to unlock during Season 15, Wild Seas. While many are straightforward, several can take time to complete.
To complete all the available commendations, you must hunt down and defeat the two fearsome Ancient Megalodons roaming the Sea of Thieves! Taking down the Ancient Feared Redmaw and the Ancient Barnacled Dread and reaping their rewards will count toward most commendations.
With more features to arrive later during Season 15, you can expect more commendations to complete.
Hunter of the Feared Redmaw
Defeat Ancient Feared Redmaws.
To complete this Commendation, you must defeat the Ancient Feared Redmaw ten times.
The Ancient Feared Redmaw is one of two Ancient Megalodons that can be active.
If the Ancient Feared Redmaw is active, you can randomly encounter it while sailing the sea. However, you will want to reach Hunter’s Call Emissary Grade V to always find it.
Similar to how reaching Reaper’s Bones Emissary Grade V reveals all other Emissaries sailing the sea, achieving Hunter’s Call Emissary Grade V reveals Ancient Megalodons roaming around.
So, if the Ancient Feared Redmaw is active, it will be on your Map Table once you reach Emissary Grade V. It will appear as a red shark fin icon with a flame below it. If you see a different shark fin, you can always try diving to a new server to see if it has an active Ancient Feared Redmaw.

You're Going to Need a Bigger Bucket!
Attempt to extinguish the Ancient Feared Redmaw with a water bucket.
To complete this Commendation, you must throw water on the Ancient Feared Redmaw from your bucket. You can grab a bucket of water from the sea, water in your ship, or the bilge. Once you have found the giant shark and have water ready to throw, douse it on the Ancient Feared Redmaw when it is near your ship.
You can wait for it to charge your ship for a bite or sail next to it.

Mega Fire Stopper
Extinguish a fire during an encounter with an Ancient Feared Redmaw.
To complete this Commendation, you must extinguish a fire on your ship started by the Ancient Feared Redmaw.
When the Ancient Feared Redmaw bites your vessel, it will light it ablaze. When the giant shark bites your ship, lighting it on fire, throw a bucket of water on some of the fire to put it out.
Friendly Fire
Cause an Ancient Feared Redmaw to overheat and explode using fire.
To complete this Commendation, you must cause the Ancient Feared Redmaw to overheat and explode using fire. The Ancient Feared Redmaw already continually heats up until it overheats and explodes. However, you can speed up the process by damaging it with fire. You can use the Ashen Winds Skull, Ashen Roar, Firebombs, or Gunpowder Barrels.
One easier method is to shoot the Feared Redmaw with Firebombs when it charges you for a bite. The larger the flames on its back, the closer it is to exploding.

The Ancient Barnacled Dread is one of two Ancient Megalodons that can be active.
If the Ancient Barnacled Dread is active, you can randomly encounter it while sailing the sea. However, you will want to reach Hunter’s Call Emissary Grade V to always find it.
Similar to how reaching Reaper’s Bones Emissary Grade V reveals all other Emissaries sailing the sea, achieving Hunter’s Call Emissary Grade V reveals Ancient Megalodons roaming around.
So, if the Ancient Barnacled Dread is active, it will be on your Map Table once you reach Emissary Grade V. It will appear as a purple shark fin icon with a lightning bolt below it. If you see a different shark fin, you can always try diving to a new server to see if it has an active Ancient Barnacled Dread.

Dark Tides Defeat
Deal damage to the Ancient Barnacled Dread using a Trident of Dark Tides.
To complete this Commendation, you must damage the Ancient Barnacled Dread with a Trident of Dark Tides.
You can find Tridents of Dark Tides randomly on beaches, inside Siren Shrines, and Siren Treasuries. Before heading out to take down the Ancient Barnacled Dread, find a Trident of Dark Tides in one of those places.
Once you’ve tracked down the Barnacled Dread, you’ll want to destroy some of its coral and rock shields to reveal a weak spot. Once you can see a weak spot, a patch of blue, glowing scars, shoot it with the Trident of Dark Tides to unlock the Commendation.
On Eel-ectric Tides
Kill an Eel-ectric Ocean Crawler with a Trident of Dark Tides during a Barnacled Dread attack.
