For Sea of Conquest heavy spenders ($500+/month) who want to know which heroes are worth building, and which ones will drain your Conches without paying it back.
The Echo Conch and Hymn Conch economy is the backbone of hero progression in Sea of Conquest. At $500+/month, you are generating a meaningful supply of summons, and every one of those summons either builds toward a competitive formation or dilutes your investment across heroes that will eventually sit on the bench.
A tier list that ranks heroes by strength in isolation does not tell you what you actually need to know: which heroes are worth your sustained investment, which ones you can build over time, and which SP heroes justify the premium they demand.
This Sea of Conquest tier list ranks heroes by investment return across your full formation, with specific attention to SP and Limited heroes and the honest cost-benefit question that most tier lists skip.
Before the tier breakdown, here's the framework: your formation needs a durable Flagship that absorbs damage and lets your side ships work, plus specialized damage ships built around specific archetypes — Artillery, Cutthroat, Blaze, Drowning, or Strategic.
The heroes that deserve your first investment are the ones that anchor either your Flagship's survivability or your primary damage archetype's output. Everything else is secondary until your core formation is competitive.
Hero rarity in Sea of Conquest runs Legendary (orange) and Epic (blue). Legendary heroes are the ceiling for each role. Epic heroes can fill gaps and some (particularly Cursed Ed) remain relevant even in high-end formations.
SP heroes are a separate category with their own investment logic, covered at the end of this guide...
Chien is the current pillar of Flagship defense. His damage mitigation and tanking capabilities are so strong that he makes your Flagship durable regardless of formation context. He does not carry the Captain tag, but that does not matter — the defensive value he provides is irreplaceable at competitive play levels. If you are spending seriously in Sea of Conquest and have not prioritized Chien, your Flagship is underperforming.
Toothsome Tom is the best aggro-generating Captain for your Flagship right now. His kit pulls enemy attention away from your side ships and onto your tank, which is exactly the job the Flagship Captain needs to do. Combined with Chien, you have the most durable Flagship core available in the current meta. Tom is the Captain, Chien is the wall, and together they make your Flagship extremely hard to sink.
Callahan Durrach is a shielding powercreep that pushes Flagship durability to another level entirely. Running Toothsome Tom, Chien, and Callahan together creates a Flagship setup that forces opponents to pour shot after shot into it while your damage ships work uncontested. If you have these three, your Flagship is not a liability — it is a strategic weapon.
Old Ahab remains relevant as the king of fleet-wide shielding. He is not as cutting-edge as Toothsome Tom for the Captain role in the latest meta, but his fleet-wide protection makes him a swiss army knife for players who need more Flagship durability before accessing the newer Legendary options. He is also significantly easier to rank up through available summons than the newest S-tier heroes.
Cordelia is the best support in the game. Her healing, dispelling, and fleet-wide utility make her relevant across every game mode and every stage of account development. The important placement note: Cordelia heals more when the ship she is on takes more damage, which means she performs better on a high-ATK side ship than on a fully tanked Flagship. Place her accordingly and she delivers sustained value no other support matches.
Griffin is your AoE damage carry. His wide-targeting damage profile makes him the top performer against enemy formations with multiple ships. When you are attacking anything that has a formation, Griffin is the hero your Artillery ship wants. His investment return is high because AoE damage is consistently the highest-output category in formation fights.
Cursed Ed earns permanent S-tier status despite being an Epic hero. His kit applies a Cursed effect that makes affected enemies take more damage of any type and suffer extended skill cooldowns and rage reduction when hit.
That damage amplification benefits every hero on every ship in your formation simultaneously. He can be placed in any Gunner slot across your roster, meaning he stays relevant even as you add more Legendaries. The best Epic in the game and arguably the most investment-efficient hero in it.
Bones is a high-damage single-target Cutthroat Captain. His kit focuses down specific targets — the right tool when you need to eliminate an opponent's key hero or break through a flagship with heavy HP. He is a glass cannon that needs protection from your Flagship setup, but in the right formation he delivers elite single-target burst. Worth building as your Cutthroat ship primary.
Sharky is the Artillery archetype's heavy hitter for multi-target AoE. His kit launches multiple attacks against enemy formations, making him extremely effective in battles where the opponent has spread ships. The self-stun after his active skill means timing matters, but the raw damage output compensates for the positioning requirement. Worth building alongside Griffin if your budget supports both.
Season-specific Epic heroes filling support slots in Drowning and Blaze archetypes round out A-tier. Adeline fills the Gunner position on Drowning ships in S2 and makes that archetype significantly more competitive. Build these after your core formation is established.
Eileen, Kelvin Hobbes, Luna, Boa, Ophelia: These heroes provide real value in specific ship roles and content types, but none of them anchor a formation the way S-tier heroes do. Build them to fill gaps once your Flagship core and primary damage archetype are invested. Do not prioritize Conch spending toward B-tier heroes when your S-tier slots are still incomplete.
Heroes like Henry Hell, Betty, Jango, and Armstrong are early-game utility that gets replaced as your roster develops. Do not invest significant resources here. They serve their purpose in the first weeks of account progression and are then functionally retired as you build your competitive formation.
SP heroes are the most powerful heroes in Sea of Conquest by kit strength. They are also the most expensive and the most complicated investment decision in the game. Here is the framework for evaluating them honestly:
SP heroes in Sea of Conquest are not pulled from the standard Conch summon pool. They are built through dedicated event spending during a limited window — typically a seasonal event with exclusive currency and milestone tracks. Once the event ends, your ability to build that SP hero disappears until a potential re-run. This means the investment is time-constrained, front-loaded, and often substantial to reach competitive star ranks.
At the highest star ranks, SP heroes represent genuine power ceiling increases. An SP hero fully built is one of the strongest units available. The critical qualifier is fully built — an SP hero at low star ranks often does not outperform a fully invested Legendary from the standard pool. The investment is only competitive if you can build the hero to the point where the SP-specific abilities actually activate and scale.
For players spending $1,000+/month with a complete core formation, SP heroes are a meaningful next-tier investment. For players still building their Flagship core and primary damage archetype, spending on an SP hero before your S-tier Legendaries are complete is spending out of order. Build Chien, Toothsome Tom, Callahan, Cordelia, and Griffin first. Then evaluate SP heroes as the formation ceiling upgrade.
Some SP heroes are limited releases with no confirmed re-run schedule. The time pressure this creates is intentional, and it is the reason whale players make some of their most expensive reactive spending decisions in Sea of Conquest.
The discipline here is the same as any event-driven spending decision: evaluate whether the hero fits your current formation priority, whether you can reach the star rank where the kit becomes competitive within the event window, and whether your budget supports it without pulling spending from S-tier Legendary investments that are not yet complete.
If the answer to any of those is no, the timer is not a reason to buy.
The most common formation mistake in competitive gangs is members building the same heroes independently, which creates roster duplication and limits what the gang can field collectively. As Gang leader, coordinating which members build which archetypes gives your gang flexibility in Showdown o' Gangs and territory fights that a roster of identical formations cannot match.
Share this investment framework with your top spenders and map who is building Flagship defense, who is building Artillery, who is building Cutthroat. A gang where whales specialize is meaningfully stronger than a gang where every whale builds the same three heroes.
Building a competitive formation in Sea of Conquest is a sustained commitment. S-tier Legendaries require consistent Conch spending and duplicate investment to reach competitive star ranks. SP heroes require event-window budget that competes with your standing Legendary development. At $500-$5,000+/month, every purchase in that stack runs through App Store or Google Play retail, and that overhead is present on every transaction, every month.

Generally yes, but Cursed Ed is the exception. He belongs in every competitive formation regardless of how many Legendaries you have because his damage amplification benefits the entire fleet. Build him early and keep him in your roster permanently.
Yes. Cordelia is the best healer in the game and the Melody of the Ocean pack is one of the clearest value purchases available to new spenders. Get her early and start ranking her up. She is relevant through every stage of account development.
Only if your core formation (Flagship defense core and primary damage archetype) is already competitive. If your S-tier Legendaries are incomplete, building an SP hero before them is spending out of order. Finish your foundation first.
The strongest current setup is Toothsome Tom as Captain with Chien and Callahan Durrach providing mitigation and shielding. Old Ahab remains a strong alternative for the Captain role for players who do not yet have Toothsome Tom. See our full Flagship formation guide for ship part and stat recommendations.
