Upgrading Vault
Even after Elementals are collected, they are unstable.
Without Seals, Elementals leak out of their vaults at a dramatic rate — making long-term storage nearly impossible.
💧 Base Leakage
- No Seal → Elementals leak at 95% of the remaining amount per day.
- Common Seal → leakage reduced to 75% per day.
- Uncommon Seal → leakage reduced to 55% per day.
- etc
If a player wants to make real progress, they must accumulate large reserves of Elementals.
Without strong Seals, those reserves will vanish overnight.
⚒️ Importance of Vault Upgrades
Improving Vaults reduces leakage further, allowing players to hold on to much larger Elemental supplies.
Upgrading requires:
- Seals themselves (consumed in the process),
- Gold,
- Elementals,
- and of course, Hero time.
Heroes perform the upgrade mission, and their skills matter:
- Mastery → affects how fast the upgrade mission is completed.
- Efficiency → reduces the total cost in resources.
🔄 Sequential Progression
Seal upgrades must be done step by step:
- First apply a Common Seal,
- then upgrade to Uncommon,
- and so on, gradually reaching higher rarities.
🚀 How to Start a Mission
- Under the Vaults section, select an Element and click the Upgrade button
- Click Select Hero and choose the one you want
- Pay attention to the mission time cost
- Click Launch Mission
- Get excited — your hero is already rushing off on the quest!
Each step strengthens your ability to hold Elementals and unlocks new growth for your Lands.
Upgrading Seals is not optional — it is the foundation of sustained progress.
Only by securing your Elementals can you truly build a powerful kingdom.
