Hero 레벨ing System

레벨ing is the most basic form of hero upgrade. Each level increases base stats (HP, 공격, 방어).

How to Gain EXP

• Campaign Battles: The primary EXP source. Use stamina to grind stages.
• EXP Potions: Consumable items that grant EXP directly. Save these for your best heroes.
• 이벤트: Many events reward EXP potions.
• 일일 퀘스트: Provide small but consistent EXP.

레벨ing Strategy

1. Focus on 3-5 core heroes. Don't spread EXP across your entire roster.
2. 레벨 your main combat hero first (usually your best S-tier).
3. Keep economy heroes leveled enough to activate their passive bonuses.
4. Use EXP potions on heroes that are hard to grind (e.g., heroes you can't easily campaign with).

레벨 Caps

Each hero has a level cap determined by their star level (ascension tier):

• 1 Star: 레벨 30
• 2 별: 레벨 40
• 3 별: 레벨 50
• 4 별: 레벨 60
• 5 별: 레벨 70
• 6 별: 레벨 80+

To progress beyond a level cap, you must ascend the hero first.

Hero Ascension (별)

Ascension increases a hero's star level, raising their stat growth rate and level cap. This is the most impactful upgrade method.

How to Ascend

Each ascension requires:

• Duplicate hero shards (specific to that hero)
• Generic ascension materials (available from events and shops)
• In-game currency (cash)

Shard Sources

Ascension 우선순위

1. Main combat hero (usually S-tier DPS or Commander)
2. 부지휘관 combat hero (tank or support)
3. Main economy hero (Mr. Ledger or equivalent)
4. Gathering hero (Foreman)
5. 방어 hero (The Architect)

Rule of thumb: It's better to have one 6-star hero than three 3-star heroes. Focus your shards.

스킬 업그레이드s

Each hero has 3-4 skills that can be individually upgraded. Skill upgrades provide the most noticeable power increase per resource spent.

Skill 유형s

1. Ultimate Skill (Skill 1): The hero's signature ability. Always upgrade first.
2. 패시브 Skill (Skill 2): Always-active bonus. 업그레이드 second.
3. Active Skill (Skill 3): Activated on cooldown. 업그레이드 third.
4. Trigger Skill (Skill 4): Conditional activation. 업그레이드 last (if at all).

스킬 업그레이드 자재

• Skill Books: Generic upgrade material, available through events and quests.
• Special Skill 자재: Hero-specific, obtained from events and the alliance shop.
• 화폐: 현금 cost per upgrade.

업그레이드 Strategy

• Max the Ultimate first — it's the most impactful skill.
• Don't upgrade skills on heroes you'll replace. Save materials.
• During 2x skill upgrade events, spend saved materials.
• Prioritize DPS heroes' skills over support heroes' — damage scaling is more valuable.

Hero Gear & 장비

Gear provides additional stat bonuses and can be upgraded independently of the hero.

Gear 슬롯s

Each hero typically has 4 gear slots:

1. Weapon: 공격 bonus
2. Armor: 방어/HP bonus
3. Boots: 속도 bonus
4. Accessory: Special bonus (crit, dodge, etc.)

Gear Quality 티어s

• 커몬 (Gray): Basic stats
• 레어 (Blue): Decent stats + 1 substat
• 에픽 (Purple): Good stats + 2 substats
• 레전더리 (Gold): Best stats + 3 substats
• 신화 (Red): End-game gear

Gear Strategy

1. Don't invest in low-tier gear. Save upgrade materials for 에픽+ gear.
2. Match gear to hero role — DPS gets attack gear, tanks get defense gear.
3. 업그레이드 weapon first for DPS heroes, armor first for tanks.
4. Set bonuses (if available) can be game-changing. Aim for full sets on key heroes.
5. Farm gear from events rather than spending resources on the gear shop.

Gear Recycling

• Don't discard old gear — recycle it for materials.
• Upgrading gear to +3 or +5 is efficient; beyond that, costs increase exponentially.
• Replace gear as you acquire better pieces, but don't over-invest in temporary equipment.

---

Hero Bonds & Synergy

Some heroes have special bond bonuses when paired together in the same march or facility.

How Bonds Work

• Certain hero combinations unlock passive stat bonuses.
• These bonuses stack with individual hero skills.
• Bond requirements are typically thematic (e.g., two "Combat" heroes).

Notable Bond Combinations

팁: Check each hero's bond list in their profile. Plan your team around active bonds for maximum benefit.

Hero Assignment Strategy

Where you assign heroes matters as much as how upgraded they are.

Assignment Categories

1. 행군 지휘관: Leads combat marches. Your strongest combat hero.
2. Garrison Commander: Defends your base. Best defense hero.
3. Facility Staff: Assigned to buildings for passive bonuses.
4. Gathering Leader: Leads gathering marches for speed/load bonuses.

Assignment Optimization

Rotate assignments based on needs: Use economy heroes during peace, combat heroes during war.

Resource Management for 업그레이드s

Hero upgrades are resource-intensive. Here's how to manage the costs:

EXP Potion Economy

• Save EXP potions for new heroes that need to catch up quickly.
• Don't waste potions on heroes at their level cap.
• Grind campaign stages with excess stamina for passive EXP.

Shard Economy

• Never shard a hero you might use later. Even B-tier heroes have niche uses.
• Save surplus shards for ascension events that reward progress.
• Prioritize shards for your main 3-5 heroes.

Skill Material Economy

• Always keep a reserve of skill books for new hero releases.
• During rate-up events, you may pull a new hero — have materials ready to upgrade them immediately.
• Don't fully upgrade skills on temporary heroes.

Gear Material Economy

• Farm gear materials from events, not the shop.
• Recycle old gear for upgrade materials.
• Only upgrade gear you'll use long-term.

F2P vs P2P 업그레이드 Paths

F2P 업그레이드 Path

• Focus on 3 core heroes and ignore the rest.
• Prioritize one S-tier hero (from free summons/events) and max it completely.
• Use A-tier heroes as fillers — they're cheaper to upgrade and still effective.
• Be patient — upgrades come slowly without spending. Consistency wins.
• Maximize free resources from daily activities, events, and alliance.

낮음 Spender Path

• 월간 패스 accelerates all upgrades through extra gems.
• 배틀 패스 provides consistent upgrade materials.
• Focus spending on one S-tier hero rate-up rather than spreading across banners.
• Buy first-purchase bonuses during your first month for maximum value.

Whale Path

• Max your top 5 heroes in parallel.
• Rotate rate-up spending to build a diverse roster.
• Invest in gear heavily — it's the most whale-impacted upgrade system.
• Still follow counter-based team building — raw power can't overcome bad strategy.

커몬 업그레이드 Mistakes

1. Spreading resources too thin. Upgrading 10 heroes to level 30 is worse than upgrading 3 heroes to level 60.
2. Upgrading skills evenly. Always max the Ultimate first. Other skills are secondary.
3. Investing in C/D tier heroes. Even fully upgraded, they're weaker than un-upgraded A-tier heroes.
4. Ignoring gear. Gear provides significant bonuses. Don't neglect it.
5. Not using bonds. Hero bonds provide free stat bonuses — always activate them.
6. Wasting EXP on level-capped heroes. Ascend first, then continue leveling.
7. Upgrading low-tier gear. Save materials for 에픽+ gear.
8. Not checking event schedules. Many events provide 2x upgrade bonuses — time your upgrades accordingly.
