Hero System

1. Hero System Architecture

The Hero System is a core progression mechanic featuring 179 playable heroes that provide combat leadership, resource bonuses, and strategic advantages.

Heroes are organized by:
9 Camp Factions, with factional warfare bonuses.
4 Rarity Tiers (B/A/S/SS), which determine base potential.
14 Quality Grades (Q2–Q15, internally 1–14), which define level caps from 30 to 140 and stat growth.
5 Arms Types, which control troop specialization.
5 Base Statistics, each with hero-specific growth curves.

2. Hero Rarity and Quality Tiers

2.1 Rarity System (4 tiers)

Rarity controls access to higher qualities and reflects base hero potential.

Distribution:
~62% SS, ~27% S, ~9% A, ~2% B.

2.2 Quality System (14 progression tiers)

Quality determines level caps, access to skills, and stat multipliers. Advancement consumes duplicate copies and materials.

Key milestones:
Q3: first active skill.
Q4–Q7: additional skills and major stat boosts.
Q8–Q10: Gold star progression at constant or slowly rising level caps.
Q11–Q14: Platinum tiers at level 100 with increasing stat growth.

3. Camp System and Factional Warfare

Heroes belong to one of 8 active camps, providing faction bonuses and weaknesses.

Icon	Camp Name	Counters	Bonus	Heroes
	The Solari Neutral	None	None	36
	The Minutemen Teal	Vindicators	+20% damage	19
	The Vindicators Purple	Wildlings	+20% damage	17
	The Wildlings Yellow	Watchers	+20% damage	19
	Watchers Blue	Minutemen	+20% damage	20
	Lawbringers Pale Gold	Wreakers	+20% damage	1
	Wreakers Red	Lawbringers	+20% damage	1
	Spacetime Travelers Cyan	None	Neutral	7

Main warfare loop:

• Minutemen → Vindicators → Wildlings → Watchers → Minutemen.
• Counter advantage grants +20% damage against the weaker camp.

Strategic implications:
Build cross‑camp lineups to exploit counters.
Solari and Spacetime Travelers are neutral (no bonus or weakness).
Lawbringers and Wreakers exclusively counter each other.

Alliance‑based recruitment and shops (alliance heroes system).
Story and campaign rewards, hero quests, and activity events.
Fragment/shard collection and synthesis.

Details of recruitment systems are fully described in the dedicated recruitment document.

6. Leveling System

Heroes can reach up to level 140, gated by quality up to level 100 and by special currencies afterwards.

6.1 EXP‑Based Levels 1–100

Experience requirements grow nonlinearly; some notable steps:

Diamond bypass becomes extremely expensive; it exists but is not efficient for most players.

Level caps are tied to quality:

6.2 Level 101–140 (Special Currencies)

Beyond level 100, standard EXP is replaced by:
Hero Essence / Token.
Premium Essence for milestone boosts.

Example requirements:

Level 140 is an extreme long‑term goal.

7. Quality Advancement System

Quality advancement varies by hero type. Here are the three main advancement paths:

First-Gen Heroes

Tutorial and early-game heroes. Simpler advancement path but lower endgame potential.

Combat Heroes

Main roster SS and S-tier heroes. Complex advancement with higher material costs but superior stats.

Solari Heroes

Special faction heroes with unique advancement requirements and progression paths.

Advancing quality raises level caps, unlocks skills, and boosts stats. Requirements vary by hero type and quality tier.

7.1 Advancement Types

Two main consumption patterns:

• Basic Path
• Used for Q2→Q6.
• Requires fewer hero copies and more common materials.
• Advanced Path
• Used from roughly Q7 upward.
• Requires more copies and rarer materials.

Indicative pattern:

7.2 Special Advancement Paths (38 Heroes)

Enhanced progression paths are available for 38 heroes, giving rewards at specific qualities.

Typical milestones:
Q4: Initial reward package (resources and materials).
Q5: Enhanced rewards.
Q6/Q7: Premium tier packages.
Q9/Q10: Legendary milestone rewards.

Example featured heroes:
2411 (Galande) – milestones at Q4, Q5, Q7, Q9, Q10 plus promotional media.
2412 (Kelly) – similar advancement track.
2111 (Mira) – six distinct milestone rewards from Q4 through Q10.

7.3 Copy Requirements (Approximate)

Very rough total duplicate requirements from starting quality:

Exact values vary by hero and path type.

8. Skill System

Heroes typically have 4–5 skills. Skills unlock at specific qualities and can be individually leveled.

8.1 Skill Unlock Schedule

General pattern:
Q3: first active skill.
Q4: second skill (often a passive or secondary active).
Q5: third active.
Q6: fourth active.
Q7: fifth skill (only on certain heroes).

Example – Enrique

Skills:
Armor Crush (active) – AoE damage + DEF reduction.
Zombie Hunter (passive) – Bonus damage vs zombies.
Additional passive buffs unlocked at higher qualities.

Unlock progression:
Q3: Main active skill (Armor Crush) – deals weapon damage to all enemies and reduces their defense.
Q4: Zombie Hunter passive – bonus damage against zombies.
Q5–Q7: Additional passive buffs and enhanced effects.

Example – Doris (2105)

• Ironclad (teamwide damage mitigation buff).
• Efficient Gatherer (passive) – Increased gathering capacity.
• Additional passive skills for support and utility.

Unlock:
Q3: primary defensive skill.
Q4: gathering passive.
Q5–Q6: additional actives.

8.2 Skill Leveling and Materials

Skills generally have 20 levels, using skill-specific and generic materials:

Material requirements:
Hero-specific skill stones – Each hero has their own unique skill material.
Generic skill materials – Shared across all heroes for common upgrades.

Higher levels require exponentially more materials. Skill level 15 is a good baseline for most heroes.

8.3 Skin‑Modified Skills

Some special skins (like Season of War skins) replace or enhance hero skills with modified versions. See the hero skins guide for details on skill-modifying skins.

9. Skin System

Hero skins provide visual customization and in some cases, combat bonuses:

10. Special Systems
