Flint is a Generation 2 Mythic Infantry hero with a Combat subclass. He arrives around Day 40 of server age when Generation 2 unlocks — the first significant roster upgrade window after the Generation 1 heroes that most players have already invested in.

His identity is fire. Every skill in his kit either deals fire damage, amplifies fire damage, or triggers off surviving fire damage. That thematic consistency translates into mechanical consistency: Flint's Exploration and Expedition kits both reward building around him as a centrepiece rather than slotting him in as a secondary pick. Players who invest in both his skills and his exclusive gear get a meaningfully different hero than players who half-build him — Dragonbane unlocks two skills that recontextualise abilities he already has, changing how you play him rather than just adding damage.

The honest summary: Flint is one of the strongest Generation 2 investments available, the Lucky Wheel is the only efficient way to build him during his generation window, and the gem requirements are substantial enough that going in without a plan is expensive. This guide covers the mechanics, the numbers, and the decisions worth making before you spin.

Unlock & Acquisition

When He Becomes Available

Flint cannot be obtained before your server reaches Generation 2. The standard unlock timing is approximately Day 40, though minor variation by server has been observed — a small number of servers have reported Day 42–43 for the Generation 2 unlock rather than Day 40 exactly.

Once Generation 2 opens, three acquisition channels activate:

Lucky Wheel — the primary source by volume and efficiency; Flint is the featured hero during Generation 2 wheels
Hall of Heroes — a secondary source with lower volume
Daily Deals — occasional shard offers that supplement but do not replace Lucky Wheel investment

What Opens at Generation 4

At Generation 4 (approximately Day 195), the shard economy expands significantly for Generation 2 heroes:

Intel Missions begin awarding Gen 2 hero shards
Hero Hall Recruitment updates to include Flint shards
Fortress Battle rewards rotate from Generation 1 hero shards (Molly/Zinman) to Generation 2 hero shards (Flint/Philly)

If you are on a younger server still in Generation 2 or 3, these channels are not yet available. Your planning should treat Lucky Wheel as the primary lever.

Shard Requirements & Star Progression

Unlocking Flint requires 10 shards. Advancing him to five stars requires 1,065 shards total — a number worth sitting with before deciding on a target star level.

Star Level	Tier 1	Tier 2	Tier 3	Tier 4	Tier 5	Tier 6	Stars Total	Cumulative
Unlock (0★ → 1★)	1	1	2	2	2	2	10	To 1★: 10
1★ → 2★	5	5	5	5	5	15	40	To 2★: 50
2★ → 3★	15	15	15	15	15	40	115	To 3★: 165
3★ → 4★	40	40	40	40	40	100	300	To 4★: 465
4★ → 5★	100	100	100	100	100	100	600	To 5★: 1,065

The 4★ vs. 5★ Decision

The most common planning mistake is treating 5★ as the default target without accounting for the cost curve. The jump from 4★ to 5★ alone requires 600 shards — more than the entire 0★ to 4★ journey combined. Most F2P and light-spending players find that 4★ (465 shards) is the realistic ceiling during Generation 2, with 5★ becoming achievable once Generation 4 opens additional acquisition channels.

4★ is not a consolation prize. Flint's skills and Dragonbane upgrades contribute independent of star level, and the stat gains from 4★ to 5★, while meaningful, do not fundamentally change what the hero does. Getting Dragonbane to the levels that unlock both special skills often delivers more return on investment than the shard grind from 4★ to 5★.

Skill System Overview

Flint has two separate skill categories that operate in distinct game modes:

Exploration Skills are active in story missions and Arena battles. These govern Flint as an individual combatant: his personal damage output, his survivability, and his attack speed.
Expedition Skills are active when Flint leads troops on the world map. These govern his effectiveness as a commander: buffs to the troops under him and debuffs he can apply to enemies in the field.

Skill Manuals are type-specific. Mythic Exploration Skill Manuals cannot upgrade Expedition Skills, and vice versa. Both manual types are obtained from the same Lucky Wheel system, so gem investment in a wheel event advances both categories simultaneously. The question is skill priority within each category — covered below.

Exploration Skills

Fires of Vengeance

At max level (5/5): Deals Attack × 84% fire damage every 0.5 seconds. Applies a 30% damage amplification debuff to the target for 2 seconds.

Flint's primary damage engine. The two components work together rather than independently: the rapid-tick fire damage creates a consistent stream of hits, and the 30% amplification debuff causes each of those hits to land harder. In Arena, the debuff also benefits any ally attacking the same target during its 2-second window, making Flint particularly effective when paired with another high-output damage dealer firing into the same target.

The 0.5-second tick rate is fast by Exploration skill standards. Once Heat Diffusion's attack speed bonus is factored in, the practical output of this skill exceeds what the 84% multiplier alone suggests.

Priority: Max this first. Everything else in Flint's Exploration kit either amplifies or enables this skill's damage. Partial investment here delivers the weakest version of his core loop.

Incinerator

At max level (5/5): When Flint drops below 50% Health, he recovers 40% of his maximum Health. Triggers once per battle.

On its face, this reads as a pure defensive skill — a single emergency heal. That reading is accurate but incomplete, because once Dragonbane is equipped at the appropriate upgrade level, the trigger condition also fires Vengeful Task: a 24% Attack boost that lasts for the rest of the battle. This transforms Incinerator from a survival tool into a two-part event — a heal and a permanent damage buff — both activated when Flint is pushed past half health.

The once-per-battle restriction matters for Arena placement. Flint's survivability beyond that single trigger relies entirely on his Defence stat and star level. Frontlining him against sustained damage threats without sufficient gear or stars will result in second deaths he has no recovery for.

Priority: Max second. The heal value is fixed percentage-based and scales with max Health, which is determined by gear and stars rather than skill level. Get Fires of Vengeance to 5/5 before committing manuals here; then commit fully, because Incinerator's interaction with Vengeful Task makes it one of the most impactful skills in his kit once Dragonbane is in play.

Heat Diffusion

At max level (5/5): Grants Flint a 7% Attack Speed increase.

A passive multiplier on Fires of Vengeance rather than an independent contribution. Faster attack speed means more ticks of 84% fire damage per second and more frequent applications of the 30% amplification debuff. The 7% figure looks modest in isolation; its value is that it scales every other offensive action Flint takes rather than adding a flat damage number.

Priority: Max third. The compounding effect is genuine, but the marginal gain per upgrade level is smaller than the gains from maxing the skills it multiplies. It benefits from being built after the core kit is in place rather than alongside it.

Expedition Skills

Burning Resolve

At max level (5/5): Grants all troops under Flint's command a 25% Attack increase.

The most reliable skill in Flint's Expedition kit — no proc chance, no conditional trigger, no threshold to cross. Just a 25% Attack buff applied to every troop in his march from the moment the battle starts. On a full march, this compounds across every unit's damage output for the entire engagement.

Priority: Max this first among Expedition skills. Consistent, unconditional buffs to your whole force are the foundation of effective march builds, and 25% Attack across all troop types is a strong floor to build the rest of the kit on.

Pyromaniac

At max level (5/5): Each attack has a 20% chance to ignite the target. Ignited targets take 40% damage per turn for 3 turns.

A proc-based damage-over-time skill. The 20% proc chance means it does not trigger on every attack, but across a sustained engagement it reliably contributes burn ticks to total damage. Against enemies who survive multiple rounds of combat, those three-turn burn stacks accumulate meaningfully.

The interaction with Immolation is worth noting: if an enemy is both ignited by Pyromaniac and debuffed by Immolation at the same time, the burn ticks land inside the amplified damage window.

Priority: Max second. The proc-based nature limits its ceiling at lower investment levels — unconditional buffs outperform conditional ones early. Once Burning Resolve is maxed, Pyromaniac becomes the highest-value upgrade remaining.

Immolation

At max level (5/5): 50% chance to apply a debuff causing enemies to take 50% increased damage.

Immolation is the ceiling raiser for Flint's Expedition damage, not the floor. A 50% damage intake increase is significant — but the 50% proc chance means it requires the rest of the kit to already be performing for the debuff to matter when it lands. When it procs, every source of damage hitting the affected enemy during that window is amplified: troop attacks, Pyromaniac burns, and damage from allied marches all benefit simultaneously.

Priority: Max third. It is powerful when it fires, but its value is conditional on the rest of the kit being in place. Maxing Burning Resolve and Pyromaniac first gives Immolation something substantial to amplify when the proc triggers.

Exclusive Gear: Dragonbane

Dragonbane is Flint's exclusive gear item. Acquiring it and upgrading it to the required thresholds unlocks two additional skills that function on top of his standard six — and one of them changes the fundamental read on a skill he already has.

Vengeful Task

When Incinerator triggers, Flint gains a 24% Attack boost that lasts for the remainder of the battle.

This is the skill that reframes Incinerator. The heal is still valuable — 40% max Health recovery is substantial in any Arena engagement — but it is no longer the whole picture. Taking damage past the 50% Health threshold now fires both a defensive recovery and a permanent offensive buff simultaneously. The second half of any battle in which Incinerator triggers sees Flint dealing 24% more damage for the rest of the engagement.

For Arena builds, this changes how opponents should threat-assess Flint: a low-health Flint is not a diminished threat. In many cases he is a more dangerous one.

Dragonbreath

Increases the Attack of defender troops by 15% when Flint is garrisoned.

A passive garrison buff that applies without Flint actively leading an expedition. This becomes particularly relevant when players transition their primary march commander to a Generation 3 hero — Flint continues contributing to base defence value even when he is no longer your frontline expedition choice.

The Lucky Wheel: Planning Your Investment

The Lucky Wheel is the engine of Flint's progression during Generation 2. Understanding what it actually returns — in shards, in manuals, and in gem cost — is the most important planning exercise you can do before committing resources.

Spin Costs

Spins	Gem Cost	Notes
1 spin	1,500	Standard rate
10 spins	13,500	10% discount over single spins
120 spins (full milestones)	~159,000	Total to reach final milestone

Always spin in bundles of 10. The single-spin rate is less efficient, and the milestone thresholds are structured around reaching specific spin counts — not specific gem totals.

Milestone Shard Rewards

The Lucky Wheel guarantees bonus shards at five fixed spin milestones, independent of what the individual spins land on:

Spin Count	Shards at Milestone	Cumulative Milestone Total
5	5	5
15	10	15
35	20	35
70	30	65
120	50	115

Reaching all five milestones in a single wheel event guarantees 115 shards from milestone rewards alone, entirely independent of RNG outcomes. Mythic Skill Manuals follow the same milestone structure.

Individual Prize Probabilities

Reward	Probability
5 shards	4.37%
1 shard	32.81%
Mystery Pack	~6.56% (two prize slots)

Combining the shard prize probabilities: each spin has approximately a 37.18% chance to return at least one shard. The weighted expected shard return per spin is approximately 0.547 shards from random prizes alone.

Projected Returns at 120 Spins

Source	Expected Shards
Random prize returns (120 × ~0.547)	~65–66
Milestone rewards (fixed)	115
Total expected	~180–181

These are probability-based estimates. Individual wheel outcomes will vary — some players will exceed this range, others will fall short. The 115 milestone shards are the predictable floor; random prize returns add variance on top.

How Many Wheels Does Flint Require?

At approximately 180 shards per full 120-spin wheel:

Target	Shards Needed	Full Wheels (approximate)
Unlock (1★)	10	Reachable at the first milestone (~5 spins)
2★	50	Less than one full wheel
3★	165	~1 full wheel
4★	465	~2.5–3 wheels
5★	1,065	~6 wheels

The Lucky Wheel appears multiple times during Generation 2, though the exact count varies across servers. Plan conservatively: budget for 2–3 complete wheels if targeting 4★. If targeting 5★, expect the grind to extend into Generation 4 when additional acquisition methods come online.

Free Spin Opportunities During State vs State Preparation Phase, players on servers where the Lucky Wheel timing overlaps with the event may receive 5 additional free spins on day 2 as a milestone reward. Whether this applies to your server depends on your SvS and wheel scheduling.

Skill Manual Acquisition

Mythic Exploration Skill Manuals and Mythic Expedition Skill Manuals are both obtained through the Lucky Wheel:

Milestone rewards include manuals alongside shards at the five fixed spin thresholds
Mystery Packs (a Lucky Wheel prize type) contain a variable quantity of manuals, reported at 2–4 per pack

Because both shard and manual acquisition run through the same Lucky Wheel investment, gem spend on a wheel event advances both shard count and skill levels simultaneously. There is no separate farming route for manuals during Generation 2. Your wheel participation is your manual budget.

Long-Term Relevance

Flint does not become obsolete when Generation 3 arrives. As a Generation 2 hero he remains competitive into the next window — generation power gaps are incremental, not absolute — and Dragonbreath provides passive garrison value even after he is no longer your primary expedition commander.

Expedition Lineup Frameworks: How Flint fits into the captain meta.

The Fortress Battle rewards, Intel Missions, and Hero Hall Recruitment all begin supplying his shards, the path toward 5★ becomes substantially more achievable without major additional Lucky Wheel gem investment. Players who enter Generation 4 at 4★ are well-positioned to close the gap over time without another major spending push.

The players most likely to be disappointed with their Flint investment are those who spent heavily on shards but left skills and Dragonbane under-developed. The hero's ceiling — particularly in Arena, where the Incinerator into Vengeful Task sequence creates a pressure-under-fire threat profile most opponents do not anticipate — is only reachable with both skill trees maxed and Dragonbane equipped to the relevant thresholds. Shard progression and skill progression are separate budgets that both require sustained attention. A 5★ Flint with unlevelled skills underperforms a 4★ Flint with a fully developed kit.
