Hero Wars Nightmare Abode | Somna Event Guide
The Hero Wars Nightmare Abode event puts the spotlight on Somna, the newest hero joining the roster. This special event follows a structure similar to new hero events, bringing event quests, valuable rewards, and opportunities to strengthen Somna.
This guide covers everything we know so far about the Nightmare Abode Event — from quest progression and reward priorities to resource planning and event value. Preparing early lets you maximize your rewards, avoid wasting important resources, and decide whether this event is worth investing in for your Somna teams.
Somna Event Boss Fight
At the heart of the Hero Wars Nightmare Abode event lies the Somna boss fight. Similar to the Fluffy, Lyria, Byrna, and Cascade events, this challenge is expected to focus more on survival and consistency than on pure damage.
• Each round your team survives, you earn event coins.
• Event coins can be exchanged in the Nightmare Abode shop for Somna soul stones, upgrade items, and other valuable rewards.
• Once defeated, you can re-enter the fight and continue gathering coins.
• Success depends on lineups with strong healing, protection, and defensive synergy.
The longer you survive, the more coins you collect, making endurance the true strategy of the Nightmare Abode Somna event.

Somna Event Rewards: Nightmare Abode
The Somna event introduces a series of seven unique boss fights, each tied to a different chapter of the Hero Wars Nightmare Abode storyline. Each stage requires a specific number of Energy Crystals to progress, and defeating the boss grants valuable resources such as event coins, Somna soul stones, upgrade items, skin stone chests, and other useful rewards.
Remember — the Energy Crystals shown in the table below are per chapter only, not cumulative. To unlock all buffs and claim every reward, you will need to progress through all seven chapters step by step. This structure makes the Nightmare Abode event both a resource challenge and a tactical progression path for players aiming to maximize their gains.
Somna Chapters & Rewards: Nightmare Abode
These are the seven boss-fight chapters for the Nightmare Abode event. The rewards follow the same structure as similar special hero events. Energy Crystals are per chapter, not cumulative.

Careful planning is needed to reach the final unlock and avoid wasting valuable resources during the Somna Event.

Somna
Upgrading Somna to 6★ requires a significant investment of Valor Coins, and the exact amount depends on your Grail of Generosity relic level. The higher the relic level, the lower the Valor Coin cost for each upgrade.
At lower star ranks, the difference isn’t dramatic. But once you’re aiming for Somna’s final stars, the reduction from Grail upgrades saves a massive amount of coins. This makes upgrading the relic an essential step if you plan to fully develop Somna during the Nightmare Abode Event.
The table below shows how many Valor Coins are needed for each star rank at different Grail of Generosity levels:
Valor Coins Needed for Somna Upgrade (based on Grail of Generosity)
Somna Event Relics: Nightmare Abode Event
Three relics define the Somna Event. Each provides unique benefits and upgrade paths:
- Tome of Greed: Grants extra Stall Coins whenever you spend energy. Can be upgraded to level 15.
- Grail of Generosity: Reduces reward costs in The Ritual’s Price. 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 Nightmare Abode 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
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 Nightmare Abode Event.
The table below lists the energy cost per level and the total Valor Coin bonus at that level.

Energy Cost (per level)Grail of Generosity Upgrade Costs
The Grail of Generosity relic in the Nightmare Abode Event reduces the cost of rewards in The Ritual’s Price. Each level you upgrade lowers the price, allowing you to stretch your Valor Coins further. Since upgrading requires energy, it’s important to know exactly how much you’ll need at each stage and how much of a reduction you’ll unlock.
The table below lists the energy cost per level and the coin cost reduction you gain in The Ritual’s Price. Use this information to plan your energy spending and decide how far to push the relic during the Nightmare Abode Event.

Energy Requirements For Boss Fight: Hero Wars Nightmare Abode Event
Completing all Somna bosses in the Nightmare Abode Event fights requires 790 energy in total. With chapter-by-chapter breakdowns available, players can calculate exactly how much they need before spending.
Once this threshold is met, any additional energy can safely be directed toward upgrading relics like the Tome of Greed and Grail of Generosity.
