Quick Answer

Crimson Sentinel is an Epic ship, it is completely free, and it expires.

It comes from the Pirate King's Trail, a 7-day beginner event, alongside the Epic healer Madame Lulu. Miss the window and there is no second chance.

It deals both Blaze and Drowning damage-over-time, which makes it genuinely unusual — most hulls commit to one damage type. And since a 6-star Epic beats a 2-star Legendary, a free Epic you can fully upgrade outperforms a Legendary you rolled once and cannot finish.

If you are in your first week, go claim it now. This is the highest-value thing a new account can do.

Why a Free Epic Beats a Rolled Legendary

Shipbuilding gives you 62% Rare, 28% Epic, 10% Legendary, and built ships roll random skills. So the realistic outcome of chasing a Legendary early is: you don't get one, and if you do, its skills may be wrong.

Crimson Sentinel skips all of that. It is guaranteed, it is Epic, and you can pour every upgrade material you have into it knowing it will not be superseded for months.

The same logic makes Providence — the Epic tank from Season 2's 30-day Sea Voyage event — worth claiming too. Between them, a new account can field two solid Epic hulls without a single pull. See the ship tier list.

Dual Damage Over Time

Crimson Sentinel deals Blazing and Drowning, and the numbers explain when it works:

	Blazing	Drowning
Damage	10% of ATK per second	20% of ATK per second
Duration	8 seconds	5 seconds
Stacks	Up to 10	Up to 10
Special	—	Ignores armour

Two consequences:

It needs fights that last. Both effects stack to 10 over 5–8 seconds. In a three-second exchange neither reaches meaningful value, which is why damage-over-time underperforms in fast PvP.

It is excellent against armour. Drowning ignores armour entirely, so Crimson Sentinel keeps working against tanks and sea monsters that shrug off direct damage. That is a genuinely valuable niche for a free ship to occupy.

Crewing It

The three slots, matched to Blazing for the free +20% attribute bonus:

Slot	Hero
Captain	Lester — the Blaze Captain, applies burning
First Mate	Will — Epic blaze First Mate, free from Azure Promise day 2
Gunner	An amplifier such as Cursed Ed, or a rage hero

For the Drowning side instead: Barnacle as Captain and Eileen (Epic drowning First Mate) or Adeline as Gunner.

Rage matters here. Damage-over-time has to be applied by skills, and skills cost rage — so Oscar (cuts skill cost by 2 early) and Wanda (accelerates rage generation) raise its real output more than flat damage would. See the combat mechanics guide.

Gems: yellow matched to whichever damage type you are building around. A mismatched yellow gem contributes literally zero — see the captain equipment guide.

How Long Does It Stay Good?

Longer than you would expect. Epic hulls that are fully upgraded hold their own well into the mid-game, and the Drowning component keeps it relevant against armoured targets even after you have better hulls.

Upgrade it properly rather than hoarding materials for a Legendary you may never build. The same argument applies here as to heroes: finished beats theoretical. See the ship upgrade requirements guide for parts and set bonuses.

FAQ

How do I get the Crimson Sentinel?

From the Pirate King's Trail, a 7-day beginner event. It also awards the Epic healer Madame Lulu.

Is Crimson Sentinel good?

Yes — a free Epic with dual Blaze and Drowning damage, and fully upgradeable, which matters more than rarity.

Can I still get it after 7 days?

No. The event window is a hard deadline for new accounts.

What heroes should crew it?

Lester as Blaze Captain with Will as First Mate, or Barnacle and Eileen for the Drowning side.

Is it good in PvP?

Less so. Damage-over-time needs 5–8 seconds to stack, and player fights often end faster.

Is it worth upgrading fully?

Yes. A fully upgraded Epic outperforms a half-finished Legendary, and the Drowning component keeps it useful against armour.

Dual Blaze and Drowning damage-over-time — unusual for one hull.
Drowning ignores armour, giving it a lasting niche.
