Principle of Light Lumira Event – New Light Titan
Get ready for the Hero Wars Lumira Event: Principle of Light — an all-new event spotlighting the Titan Lumira and Apollo that brings a fresh mini-season format, a dedicated event map, and brand-new buff mechanics.
Much like the previous Verdoc event, you’ll navigate through several chapters featuring both hero- and titan-style battles, collect exclusive event items, and unlock major rewards by defeating bosses once you’ve amassed enough buffs.
With proper currencies like Valor Coins, Energy Crystals and Sapphire Medallions, expert shops and relic upgrades, the Hero Wars Lumira Event isn’t just another event — it’s a pure power grind to the next tier of your roster.
Hero Wars Lumira Event: Principle of Light – Overview
The Hero Wars Lumira Event: Principle of Light introduces the mighty Titan duo Lumira and Apollo, offering a new way of doing Titan events in Hero Wars. It merges a new adventure map, relic upgrade, and some currencies into a single progression-based, strategic experience.
- A dedicated adventure map consisting of seven chapters, exclusive bosses, and challenge scaling that pushes heroes and titans.
- A mini-season format such as that of the Guus and Verdoc events, in which reward for repeated play is rewarded by long-term progress indicators.
- A powerful Workshop system for upgrading Relics and unlocking Star Ring buffs to optimize rewards and combat potential.
- New event currencies — Energy Crystals, Valor Coins, and Sapphire Medallions — each linked to a special activity like battles, quests, and the Festival Gacha.
- An exclusive Festival Shop that employs Sapphire Medallions for exchanging Lumira and Apollo materials, Titan relics, and upgrade resources.
Unlike previous events, the Hero Wars Lumira Event: Principle of Light focuses both on hero and titan growth, calling for conscious energy management, relic optimization, and thoughtful usage of resources in order to maximize the potential of Lumira and Apollo.
Lumira Skills – Hero Wars Lumira Event
Lumira and Apollo are a Light element Summoner duo fighting from the Back Line. Lumira summons Apollo to redirect damage taken by allies to himself — and when Apollo falls, he grants the entire team a brief moment of invincibility. Here are their two key skills:
Apollotropia
Summons Apollo. While active, he spreads an aura that redirects part of the damage taken by allies within the aura to himself, up to a limit based on his Attack. When Apollo dies, allies in the area become invincible for 1 second. Apollo’s health depends on Lumira’s maximum health. Apollo can’t be attacked directly.
Spiritual Bond: Light
Lumira and Apollo start resonating and form a bond with the Light element. Thanks to it, they begin the battle with additional Energy and generate more Energy for Light Totem activation.
Hero Wars Lumira Event – Principle of Light Boss Battle
The Hero Wars Lumira Event: Principle of Light chapter-ending bosses can be accessed by reaching the respective buffs. Titan and hero fights alternate in raids, so preparation and synergy among your team is more critical than your damage.
Here in this section (when the event starts), I’ll provide per-chapter strategies with images of the exact same heroes or titans that you will need for each fight—so you can swipe the lineups and conquer each stage efficiently.
This submission type allows the Hero Wars players to submit their boss fight teams for the Lumira Event. Players can submit a screenshot of the team they used, identify the chapter and the battle type (heroes or titans), and leave brief comments on their strategy. Each submission is sent directly to the team at Olympus through email to help build a guide to the community consisting of real player-tested teams and tactics.

Unlocking Lumira and Apollo – Principle of Light
To unlock Lumira and Apollo during the Principle of Light event, players must collect 3,130 soul stones. These can be obtained from event progress, Valor Coins, and limited-time bundles that are rolled out for the event. Below is the amount of soul stones required for each star rank. The final evolution requires planning and constant activity throughout the event.
Lumira and Apollo Soul Stone Upgrade
To unlock and evolve Lumira and Apollo during the Principle of Light event, players must collect a total of 3,130 Soul Stones. Each star rank requires a specific number of stones, as shown below. Progress accumulates through event rewards and bundles.
Valor Coins Needed for Lumira and Apollo – Principle of Light
Purchasing Lumira and Apollo to higher star levels costs a large amount of Valor Coins, which are acquired through event rewards and fighting bosses within the Principle of Light event.
Each level represents the strength of Lumira’s relic upgrades and determines how well their elemental and primal energy rank in battle.
The greater the chapter and relic level, the higher coin investment to move forward.
The graph below indicates the estimated Valor Coins to increase Lumira and Apollo’s stars at different levels with the average 10% grand prize drop rate assumed.
Remember that outcomes may differ — lucky draws will decrease the overall expenditure, whereas botched jackpots will do the opposite.

Lumira Artifact Tome of Belav – Hero Wars Lumira Event
Lumira’s exclusive first artifact — Tome of Belav — is her elemental weapon, boosting Elemental Damage. While its stats are relatively minor compared to her overall Titan power, it remains one of the most valuable event-limited artifacts in the entire game.
It only appears during the Lumira event and can’t be obtained normally from the campaign or any regular chests.
It is only available to buy during the event from the Festival Shop, Battle Pass, or Mystery Island. The players need to make sure to obtain it while it’s still available, as it may not return for a few months after the event finishes.
If not seen, it will stay locked up until its next rotation during a Titan event.
| ★ | Fragment | Fragment (Total) |

| 2 | 440 | 500 |
| 3 | 1,400 | 1,900 |
| 4 | 2,500 | 4,400 |
| 5 | 5,000 | 9,400 |
| 6 | 9,000 | 18,400 |
Lumira Artifact Cosmos’s Seal – Hero Wars Lumira Event
Cosmos’s Seal is Lumira’s third artifact, boosting Attack and Health and shared among Summoner-type Titans.
It increases Lumira’s base stats and plays a key role in maximizing her performance in both offense and defense.
This artifact can also be obtained through the Festival Shop, Battle Pass, or Mystery Island — but like Tome of Belav, it is available only during the Lumira event.
Further copies purchased from this event are meant to be used by other Titans in the future, so it’s worthwhile even in addition to its present usefulness to Lumira.
If missed, it will be unavailable until another future return of this event.
| ★ | Fragment | Fragment (Total) |

Hero Wars Lumira Event – Principle of Light Relics
Three relics define the Hero Wars Lumira Event: Principle of Light. Each provides unique benefits and upgrade paths:
- Tome of Greed: Grants extra Valor Coins whenever you spend energy. Can be upgraded to level 15.
- Grail of Generosity: Reduces reward costs in the Altar of Fate. Can be upgraded to level 18.
- Amulet of Battle: Boosts buffs during boss fights to strengthen your lineup.
Upgrading relics requires strategic resource allocation. The Principle of Light event doesn’t offer a single “optimal” route — players must balance between relic upgrades, boss fights, and energy management.
Tome of Greed — Energy & Valor Coin Bonus – Principle of Light
Tome of Greed adds more Valor Coins for the event as you spend energy.
Each level increases your bonus by +1,000 Valor Coins. Because upgrades cost energy, it’s best to push this relic before you start heavy energy spending during the Principle of Light event.
The table below lists the energy cost per level and the total Valor Coin bonus at that level.
| Level |  Energy Cost (per level) |
Valor Coin Bonus (at level) |
|---|---|---|

Grail of Generosity Upgrade Costs – Principle of Light
In the Principle of Light event, the Grail of Generosity reduces the cost of rewards in the Altar of Fate. Each level you upgrade lowers the price, letting you stretch your Valor Coins further. Because upgrades consume energy, it’s key to know the energy required at each step and the discount you unlock.
Use the table below to see the energy cost per level and the coin-cost reduction in the Altar of Fate. Plan your energy spend to decide how far to push the Grail during the Principle of Light event and avoid overpaying for rewards.
| Level | Energy Cost |
 Reduction in Altar of Fate Cost |
|---|---|---|
| 1 | 0 | 100 (2800 → 2700) |
| 2 | 10 | 200 (2800 → 2600) |

| 18 | 100 | 1800 (2800 → 1000) |
| Total | 1250 |
Energy Requirements for Boss Fights
Completing all boss battles in the Principle of Light event requires a total of 790 Energy. Each chapter has its own Energy requirement, allowing players to plan exactly how much they’ll need before beginning their runs.
Once you’ve covered the full boss-fight energy cost, any remaining Energy can be used to upgrade relics such as the Tome of Greed and the Grail of Generosity, helping you maximize rewards and efficiency throughout the event.

FAQ — Hero Wars Lumira Event: Principle of Light
The Hero Wars Lumira Event: Principle of Light is a time-limited event dedicated to the new Titan duo, Lumira and Apollo. Players explore a themed map, defeat bosses, and earn special resources used to upgrade titans and relics.
Defeating all bosses requires approximately 790 energy. Any additional energy can be directed toward upgrading relics like the Grail of Generosity to lower costs in the Altar of Fate.
This relic reduces the cost of rewards inside the Altar of Fate. Upgrading it allows players to spend fewer Valor Coins when exchanging for event rewards, making it a smart long-term investment.
The Golden Ticket unlocks the premium side of the Lumira Battle Pass, offering significantly higher quantities of key resources such as Titan Potions, Artifact Spheres, Skin Stones, and exclusive items like Lumira’s avatar and exclusive artifacts.
Absolutely. The free side of the Battle Pass still provides a balanced mix of Emeralds, Energy Crystals, Bottled Energy, and Titan resources. Even without the Golden Ticket, consistent play yields great progress.
Experience is earned through event missions, energy spending, and completing boss fights. The more active you are during the event, the faster you unlock both free and premium rewards.
Plan your energy usage in advance, upgrade relics only when necessary, and prioritize boss completions before upgrades. Collect and open resource chests toward the end of the event for maximum efficiency.
