AFK Journey: Celestial and Underworld Hero Development Guide: Resource Investment and Prioritization

In AFK Journey, with the constant addition of new heroes, effectively allocating resources to enhance all-around strength becomes a crucial challenge for every player. Different heroes perform significantly differently in PvP, Dreams, Endless Mode, and AFK phases, so establishing strategic development priorities can significantly improve your team's effectiveness. This guide will provide a detailed breakdown of the usefulness, development order, and resource investment recommendations for all Celestial and Underworld heroes, helping players achieve optimal growth in the game.

Core Essential Heroes: Account Building Basics

Elijah & Lailah

Elijah and Lailah are the most essential heroes in the current meta, playing a decisive role in AFK phases, Dreams, and PvP battles.

Core Value: Their ultimate abilities and unique weapons significantly enhance the overall team's effectiveness.

Usable in all game modes, including Endless Mode and boss challenges.

Development Strategy: It's recommended to upgrade both heroes to Supreme+ as soon as possible to ensure continued effectiveness in high-difficulty levels and ranked battles.

Operation Tips: Elijah and Layla can flexibly fill dual roles as damage dealers and support within a team. Their skill sets can inflict significant damage to enemies while also enhancing their teammates' survivability.

Reinier

As a veteran Celestial/Underworld hero, Reinier's value has remained stable and continues to grow.

Core Mechanics: Unique repositioning and damage transfer abilities, particularly useful in the endless phase preceding the Dream boss.

Development Strategy: Simply upgrade to Mythic+ to play a core role, requiring only eight Hero Cards.

Resource Investment: Low initial investment, significant results, and a substantial boost to overall account progress.

Practical Tips: Reinier is a near-essential player in the endless phase of the Dream and defensive PvP lineups. His skill set significantly reduces the team's incoming damage and creates space for core damage dealers to deliver damage.

Secondary Heroes: Key Damage and Buffs

Baelran

Baelran is a Celestial Hero with powerful area-of-effect control and true damage.

Core Value: True damage penetrates enemy defenses, while offering high durability and destructive power.

Useful Scenario: Advancing into the Campaign and Arena stages, especially after acquiring core essential heroes.

Development Strategy: After Elijah, Lyra, and Rainier, Baelran should be your next development priority.

Phraesto

Although Phraesto was once a top-tier hero, his utility in early boss encounters has declined with the introduction of new heroes.

Skill Traits: Damage is based on enemy health, primarily effective on Endless difficulty.

Development Strategy: It is recommended to use him as a support component or a tactical tool for specific boss encounters, rather than a core damage dealer.

Special Abilities: He can summon illusions, increase the number of units on the field, and provide a shield bonus, still offering some strategic value.

Harak

Harak is a somewhat niche meta hero, but excels in certain boss encounters.

Mechanic: Increases critical strike rate and haste at the start of the fight, and consumes the weakest unit for bonus damage at the end.

Development Strategy: Must be used in conjunction with Fraestor to maximize his potential.

Practical Tip: In Endless Mode, the absence of Harak will significantly reduce damage scores. It is recommended to develop him after establishing a core lineup.

PvP and Niche Heroes: Strategic Investment

Saida

Saida offers powerful damage and crowd control during AFK phases, but the investment cost is high.

Development Barrier: Requires at least +15 for the exclusive weapon to reach its full potential.

Strategic Value: If the original boss, Crystal Crawler, is added to the Dream Cycle in the future, Saida will become a high-priority pick.

Dunlingr

Dunlingr is a skill-based PvP hero whose value depends on the number of other heroes a player has.

Suitable for: High-spending players with diverse lineups can fully utilize his abilities.

Development Strategy: Free-to-play or low-spending players can hold off on investment and prioritize core essential heroes.

Cryonaia

Cryonaia is a high-burst nuke hero that freezes enemies and deals area damage.

Resource Requirements: High acquisition and upgrade costs, primarily suited for premium player lineups.

Practicality: Excellent in PvE, but lacks self-healing, so investment should be cautious.

Kulu

Kulu has some utility in AFK and PvP, but is generally a low priority.

Development Recommendation: Use only as a supplemental hero, not a priority for resource investment.

Skipable Heroes: Low resource allocation

Tarlin: Average performance across all modes, replaced by stronger active heroes.

Dionel: While bursty, not suitable for prioritizing resources.

Scarlita: Unstable ultimate, serves only as a support bonus.

Berial: Virtually useless in PvE, lacks versatility, and resource investment is not recommended.

Strategy Tip: Unless you've already invested heavily in these heroes or have no other options, avoid building them to avoid wasting limited resources.

Build Priority Summary

Core Essential Heroes: Elijah & Lyra, Rainier → Comprehensive coverage in AFK, Dream, and PvP.

Key Damage Hero: Balran → Core damage and balanced offense and defense.

Support and Niche Heroes: Fraesto, Harak, Seda → Effective in specific scenarios.
