Seal Upgrades
Even after Elementals are collected, they are unstable.
Without Seals, Elementals leak out of their Vessels at a dramatic rate, making long-term storage nearly impossible.
💧 Base Leakage
- No Seal → Elementals leak at 95% of the unprotected amount per day.
- Common Seal → leakage is reduced to 75% per day.
- Uncommon Seal → leakage is reduced to 55% per day.
- Rare Seal → leakage is reduced to 35% per day.
- Epic Seal → leakage is reduced to 15% per day.
- Legendary Seal → leakage is reduced to 5% per day.
If a player wants to make real progress, they must accumulate large reserves of Elementals.
Without strong Seals, those reserves will vanish overnight.
🛡️ Protected Reserve
Seals now do more than reduce the daily leakage rate.
They also create a protected reserve inside the Vessel.
Elementals inside this protected reserve do not leak away.
The stronger the Seal, the larger the protected reserve becomes.
| Seal Level | Leakage per day | Protected reserve |
|---|---|---|
| No Seal | 95% | 5% of Vessel capacity |
| Common | 75% | 10% of Vessel capacity |
| Uncommon | 55% | 15% of Vessel capacity |
| Rare | 35% | 20% of Vessel capacity |
| Epic | 15% | 25% of Vessel capacity |
| Legendary | 5% | 30% of Vessel capacity |
This means a stronger Seal both slows losses and protects a small stored amount from leakage entirely.
⚒️ Importance of Seal Upgrades
Improving Seals reduces leakage further and protects a larger reserve, 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 Seal mission is completed.
🔄 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.
Each Seal must match the Vessel's Element.
For example, upgrading a Fire Vessel's Seal requires a Fire Seal of the required rarity.
🚀 How to Start a Mission
- You must reach at least Profile Level 3 to start this mission.
- Under the Elements section, choose the Vessel whose Seal you want to improve and click the Upgrade button
- Click Select Hero and choose the one you want
- Pay attention to the mission time cost
- Click Launch Mission
- Your Hero will begin the Seal upgrade mission
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.
