Rise of Kingdoms Technology Research Calculator
In Rise of Kingdoms, technology research in the Academy is crucial for strengthening your city and armies. Each research level provides significant buffs, but also demands substantial resources and time. This calculator helps you estimate the actual time and resources needed for a specific technology research, taking into account your various research speed buffs.
Understanding the true cost and time allows you to plan your resource gathering, speedup usage, and overall development strategy more effectively. Whether you're pushing for T5 troops or optimizing your gathering efficiency, knowing your research requirements is key.
How to Use the Calculator:
- Base Research Time: Enter the time displayed in the game for the technology you want to research, before any speed buffs are applied. This is usually shown in hours.
- Base Resource Costs: Input the base Food, Wood, Stone, and Gold costs displayed in the game for that technology level.
- Base Power Gained: Enter the amount of power the technology grants upon completion.
- Total Research Speed Buff (%): This is the sum of all your active research speed buffs. This includes alliance buffs, VIP level buffs, runes, commander skills (e.g., Eulji Mundeok, Cleopatra), kingdom buffs, and any event-specific buffs. For example, if you have a 20% alliance buff, 10% VIP buff, and a 15% rune, your total buff would be 45%.
- Click "Calculate" to see the adjusted research time and total resource requirements.
Understanding Research Speed Buffs
Research speed buffs are paramount in Rise of Kingdoms. They directly reduce the time required to complete technology research, allowing you to progress faster and gain a competitive edge. These buffs stack additively. For instance, if you have a 20% alliance research speed, 10% VIP bonus, and a 15% rune, your total research speed buff is 45% (20 + 10 + 15).
Always aim to maximize your research speed buffs before initiating a major research project. This can save you countless speedups and resources in the long run. Common sources of buffs include:
- Alliance Technology: Your alliance's research in the "Alliance Technology" tree.
- VIP Level: Higher VIP levels grant significant research speed bonuses.
- Runes: Found on the map, runes can provide temporary research speed buffs.
- Commanders: Certain commanders (e.g., Eulji Mundeok, Cleopatra, Theodora) have skills that boost research speed when assigned as a secondary commander to your city.
- Kingdom Buffs: During certain events or kingdom-wide decisions, temporary buffs might be active.
- Events: Special events often provide temporary research speed boosts.
Example Calculation:
Let's say you want to research a technology with the following base stats:
- Base Research Time: 100 hours
- Base Food Cost: 5,000,000
- Base Wood Cost: 4,500,000
- Base Stone Cost: 3,000,000
- Base Gold Cost: 1,500,000
- Base Power Gained: 15,000
And your total research speed buff is 45%.
Using the calculator:
- Adjusted Research Time: 100 hours / (1 + 45/100) = 100 / 1.45 ≈ 68.97 hours
- Actual Food Cost: 5,000,000 (assuming no resource cost reduction)
- Actual Wood Cost: 4,500,000
- Actual Stone Cost: 3,000,000
- Actual Gold Cost: 1,500,000
- Total Power Gained: 15,000
This shows that with a 45% buff, you save over 31 hours of research time!
