How to Level Up Heroes Efficiently in Sea of Conquest

Collect skill books from routine missions and quests, focus scarce materials on heroes that fit your ships and are realistic to develop, and verify older level-cap advice in-game.

For efficient hero leveling in Sea of Conquest, collect skill books through routine missions and quests, invest in a small group of heroes suited to the ships and roles you use, and keep advancing your Adventure Level. Treat Adventure Level’s effect on the hero level cap as older, unconfirmed guidance: check the live game before planning around it. Current XP costs, caps, and drop rates are not established in the available sources.

Hero levels and Adventurer Level are different

Hero levels use skill books, which Pocket Gamer identifies as rewards from missions and quests. Adventurer Level is account progression: it rises through tasks and unlocks missions and story chapters. Do not confuse progress on the account track with the materials used to level an individual hero. Pocket Gamer’s beginner guide explains this distinction, though the reviewed page does not show its original publication date.

A practical, low-waste leveling routine

  1. Clear available missions and quests. Pocket Gamer names these as sources of skill books. Collect predictable routine rewards before looking for a specialized farming route.
  2. Choose a small core of heroes. Match heroes to the jobs and ships you actually use. The beginner guide describes specializations such as First Mate and Gunner; a roster’s intended role matters when deciding where limited resources should go.
  3. Check whether you can complete the next upgrade. Before spending scarce materials, consider a hero’s current star level and whether the needed advancement resources are realistically available. The Sea of Conquest Handbook’s roster guide recommends finishable investments for free-to-play players, weighing role, damage type, star level, and availability. The independent guide says it was checked against version 1.1.790 in September 2026; that version label is the guide’s metadata, not a guarantee about the game’s current live version.
  4. Keep moving along the Adventure track. A TalkAndroid guide from 11 March 2024 reports that Adventure Level raises heroes’ maximum level and recommends spending stamina on Adventure EXP. This is older, secondary advice, not a verified current cap rule; confirm the relationship in your game before treating it as a progression requirement. TalkAndroid’s guide contains that recommendation.
  5. Inspect current event and shop rewards. A Mobile Game Tips guide dated 13 July 2026 suggests checking missions, events, and shops for hero materials. Its specific reward and drop suggestions are not confirmed by official game documentation reviewed here, so verify the actual rewards in the current client before spending stamina or currency around them. Read the guide.

How to choose which heroes to level

There is no single best investment for every account: the right choice depends on your ship lineup, progression stage, and available resources. Compare candidates on these factors before using scarce materials:

  • Role and ship fit: Prioritize heroes whose specialization serves a position or ship you rely on.
  • Damage type: Consider how the hero fits the damage needs of your lineup.
  • Current stars and upgrade path: A hero is a more practical investment when you can make meaningful progress with the advancement materials you can obtain.
  • Availability: Favor a hero you can realistically finish over a newer option whose required resources are out of reach. This is the roster guide’s stated free-to-play investment principle.

Use premium currency cautiously

Pocket Gamer says Emeralds can be used “in a pinch.” That makes them an optional fallback, not a default leveling method or a proven best-value purchase. Collect routine skill-book rewards and assess your roster before deciding whether spending Emeralds is worth it.

What is not established about current leveling

The official Sea of Conquest site confirms the game and publisher context, but the official material reviewed does not provide a current hero XP curve, upgrade-material costs, complete level-cap table, or detailed drop rates. Those values should be checked in the live hero upgrade interface rather than inferred from older guides. Avoid relying on a fixed farm route or promised yield unless the game currently shows it.
