Nightmare Abode Event Optimizer | Somna Calculator

Nightmare Abode Event Optimizer

The Nightmare Abode Event Optimizer helps players plan their resources strategically for the Nightmare Abode Event, especially when unlocking advanced chapters in special adventures. Dedicated to the new hero Somna, this event follows the same pattern as other Hero Wars events. It brings together multiple quests and layered requirements that reward both free-to-play effort and tactical spending.

Fixed Energy Sources in the Nightmare Abode Event Optimizer

Every participant begins with a guaranteed amount of energy available through standard quests. These rewards are accessible to all players:

  • Free Quests → 424 energy
  • Gifts from Devs/Hero Wars → 16 energy per gift (up to 3 gifts are sent across the event)
    • 1 Gift = +16 energy
    • 2 Gifts = +32 energy (total)
    • 3 Gifts = +48 energy (total)
  • Battle Pass → 150 energy (optional, unlocked if you purchase it)
Example: Without spending any emeralds or sapphire medallions, you can gather up to 622 total energy if you receive all 3 gifts and activate the Battle Pass (424 + 48 + 150 = 622). That total is enough to reach Chapter 6, which requires 530 energy. To unlock Chapter 7, however, you’ll need 790 energy — so additional sources become necessary.

Emerald Spending Rewards

The Emerald Flow quests provide one of the most effective methods to gain additional event energy. These rewards are cumulative — meaning each higher milestone automatically includes the rewards from previous tiers.

Emeralds Spent Energy Earned
1001
5003
3,0006
7,0009
12,00012
18,00016
25,00020
35,00026
50,00034
70,00044
90,00054
120,00070
150,00090

Spending the full 150,000 emeralds during the event will earn you 90 extra energy, which can significantly help in reaching Chapter 7.

Sapphire Medallion Spending

The Sapphire Medallion quests follow a cumulative pattern. As your total spend climbs, so does your energy reward. Nightmare Abode also includes two extra tiers — 120 and 150 medallions — that provide bonus energy on top of the base amount:

Medallions Spent Total Energy Earned
33
66
1010
2020
3030
4040
5050
6060
7070
8080
9090
100100
120110
150120
Note: At 120 medallions you earn 110 total energy (100 base + 10 bonus), and at 150 medallions you earn 120 total energy (100 base + 20 bonus). Completing the top tier gives you 120 additional energy — a meaningful boost toward Chapter 7.

Energy Crystal Exchange Feature

Built into the tool is an Energy Crystal Exchange system that allows you to convert your event energy crystals directly into Valor Coins. This feature is particularly useful when you’ve already cleared all the chapters you want and prefer to maximize your Valor Coin collection for more soul stone spins.

How the Exchange Works

  • Base Rate: 500 Valor Coins per energy crystal
  • Tome of Greed Bonus: Additional 100 Valor Coins per crystal for each Tome level
  • Example: Level 5 Tome = 500 base + 500 bonus = 1,000 coins per crystal
  • Example: Level 10 Tome = 500 base + 1,000 bonus = 1,500 coins per crystal
Strategic Use: Exchange energy crystals once you’ve already unlocked your target chapters and want to maximize soul stone collection. Exchanged crystals are automatically deducted from your remaining energy, so you can see exactly how many chapters remain within reach. A warning appears if exchanging would cost you a chapter.

Tome of Greed & Grail of Generosity

Your Tome of Greed and Grail of Generosity relic levels are integrated automatically, so every downstream number stays accurate:

Tome of Greed Benefits

  • Energy Cost Deduction: Reduces total energy needed (max 840 energy saved at Level 15)
  • Valor Coin Multiplier: Converts energy crystals to Valor Coins (100 coins per crystal per level)
  • Bonus Rewards: Fixed bonus Valor Coins for upgrading (up to 112,000 total at Level 15)
  • Exchange Rate Bonus: Increases energy crystal exchange value by 100 coins per level

Grail of Generosity Benefits

  • Energy Cost Deduction: Reduces total energy needed (max 1,250 energy saved at Level 18)
  • Spin Discount: Reduces Valor Coin cost per spin (100 coins discount per level)
    • Level 1: 2,700 coins per spin
    • Level 10: 1,800 coins per spin
    • Level 18: 1,000 coins per spin
  • Valor Coin Conversion: Energy spent on upgrades converts to Valor Coins based on Tome level

Because these values auto-sync across all four steps, your energy, Valor Coins, and soul stone results always stay consistent with each other.

VIP Points and Battle Pass Connection

Another important energy source comes from the VIP quest chain, which grants rewards based on accumulated VIP points. You earn 6 energy for every 500 VIP points up to 5,000, then 12 energy each for 6,000 and 7,000 VIP points — so reaching 7,000 VIP points in total grants 84 energy.

Buying the Battle Pass automatically awards 1,600 VIP points, unlocking the first three VIP tiers — that’s 18 extra energy on top of the 150 Battle Pass energy. Additionally, the Battle Pass grants 25 Sapphire Medallions alongside the 4 free medallions everyone receives.

Chapter Unlock Requirements

Each chapter in the Nightmare Abode adventure has a specific total energy requirement. Here’s the breakdown:

Chapter Total Energy Needed Valor Coin Reward
1Free10,000
2Free20,000
35020,000
416020,000
532050,000
653050,000
779050,000
  • Free quests + 3 gifts alone (424 + 48 = 472 energy) — reaches up to Chapter 5.
  • Adding the Battle Pass (424 + 48 + 150 = 622 energy) — unlocks Chapter 6.
  • To reach Chapter 7, combine Emerald and Medallion spending or boost your VIP points.

Valor Coins Collection in the Nightmare Abode Event Optimizer

Valor Coin earnings are tracked from multiple sources at once:

Fixed Valor Coin Sources

  • Official Gifts: 8,500 Valor Coins per gift (0, 8,500, 17,000, or 25,500 total based on gifts received)
  • Chapter Rewards: Clearing all 7 chapters provides 220,000 Valor Coins total (10,000 + 20,000 + 20,000 + 20,000 + 50,000 + 50,000 + 50,000)

Variable Valor Coin Sources

  • Energy Crystal Conversion: Available energy × Tome level × 100 coins
  • Tome Upgrade Bonuses: Up to 112,000 bonus coins at Level 15
  • Grail Upgrade Conversion: Energy spent upgrading Grail × Tome level × 100 coins
  • Energy Crystal Exchange: Exchanged crystals × (500 + Tome level × 100) coins
  • Quest Completion: 8 different quest chains with varying Valor Coin rewards

Every one of these sources is summed automatically, giving you a single total for soul stone spins.

Somna Soul Stones & Star Level Progression

Beyond energy planning, the tool calculates exactly how many soul stones you can obtain and which star level you’ll reach for Somna:

Soul Stone Requirements

Star Level Soul Stones Required (Total)
⭐ 1★10
⭐⭐ 2★30
⭐⭐⭐ 3★80
⭐⭐⭐⭐ 4★180
⭐⭐⭐⭐⭐ 5★330
⭐⭐⭐⭐⭐⭐ 6★ MAX630

Spin Mechanics

  • Average Stones per Spin: 3.6 soul stones
  • Spin Cost: Based on Grail of Generosity level (2,700 coins at Level 1, decreasing by 100 per level)
  • Total Spins: Your Valor Coins ÷ Spin Cost
  • Total Stones: Total Spins × 3.6 (average)

Sapphire Medallions in the Nightmare Abode Event Optimizer

A dedicated Sapphire Medallions section gives a full breakdown of every medallion source, with two estimates depending on the Altar spin drop rate.

Medallion Sources

Source Medallions Notes
Free from Battle Pass 4 All players receive this regardless of BP purchase
From Official Gifts 2 per gift Up to 6 total from 3 gifts
Battle Pass Purchase 25 Only if Battle Pass is bought
From Clearing Chapters up to 37 Ch 1: 1 | Ch 2: 2 | Ch 3: 2 | Ch 4: 2 | Ch 5–7: 10 each
From Spins in Altar (10% drop) ≈ 0.10/spin Commonly observed drop rate
From Spins in Altar (15% drop) ≈ 0.15/spin Optimistic estimate — not officially confirmed
Example Calculation: If you have the Battle Pass, receive all 3 official gifts, and clear all 7 chapters with 200 total spins:

4 (free BP) + 6 (3 gifts) + 25 (BP purchase) + 37 (all chapters) + 20 (200 spins × 10%) = 92 medallions at 10% drop
4 (free BP) + 6 (3 gifts) + 25 (BP purchase) + 37 (all chapters) + 30 (200 spins × 15%) = 102 medallions at 15% drop
⚠️ Note on drop rate: The Altar medallion drop rate has not been officially confirmed by Hero Wars. The 10% rate is the most commonly observed by the community; 15% is shown as an optimistic scenario. Plan around the 10% figure to avoid disappointment.
