Upgrading Equipment with Enchanted stone and costs
Infinity Kingdom Equipment Upgrade Cost Guide (Level 15–40)
Equipment plays a crucial role in the strength of your Immortals in Infinity Kingdom. While talent setups, artifact upgrades, and Tower of Knowledge skills all matter, it’s your gear—especially epic +1 equipment—that truly skyrockets your stats as you progress into the mid and late game.
Recently, a player asked me:
“How much does it actually cost to upgrade equipment?”
I didn’t know off the top of my head—so I did the work and melted down gear to bring you this breakdown. Based on current testing (Season 1 capped at Level 40), here’s everything you need to know about Enchanted Stone costs, where to get them, and how steep the curve gets.
📊 Equipment Upgrade Cost Table (Level 15 to 40)
| Level Range | Upgrade Cost |
|---|---|
| Level 15 | 700 |
| Level 15–20 | 2,500 |
| Level 20–25 | 15,900 |
| Level 25–30 | 41,900 |
| Level 30–35 | 119,100 |
| Level 35–40 | 294,200 |
| Total Cost | 475,390 Enchanted Stones |
⚠️ Note: This is the total cost for upgrading a single piece of Epic +1 equipment from Level 15 to 40.
🔥 Where to Get Enchanted Stones
As you’ve probably noticed, the later levels get very expensive—with over 400K stones required past level 25 alone. Here’s how to stock up efficiently:
1. Defeating Gnomes
- Gnomes regularly drop small amounts of Enchanted Stones
- Great for daily farming, but won’t keep up with late-game costs on its own
2. Spider Boss Battles
- Fought twice a week
- Major source of Enchanted Stones (especially at higher difficulties)
- Your best method for stacking big amounts quickly
💡 Tip: Make sure you’re in an active alliance doing high-difficulty Spider runs—it’s by far the best bang for your time.
📈 Why Equipment Matters
Each upgrade boosts your Immortal’s core attributes:
- Physical Attack / Magic Attack
- Defense
- HP
- Speed
- Crit, Dodge, Block, etc.
By the time you’re upgrading beyond Level 30+, the stat increases are massive and can be the difference between winning and losing PvP fights or boss challenges.
🛠️ What This Means for You
- Don’t ignore Enchanted Stone farming just because early upgrades are cheap—you’ll need hundreds of thousands later
- Prioritize your main Immortals’ gear upgrades first—don’t spread resources thin
- If you’re still in Season 1 or 2, it’s best to stockpile Enchanted Stones now so you’re ready when Season caps increase
- Level 35–40 alone costs 294.2K—which is over 60% of the total upgrade cost
🔮 What’s Next?
I’m currently capped at Level 40 in Season 1, but as the server progresses and unlocks higher level upgrades, I’ll be updating this guide with:
- Costs for Level 40–50 and beyond
- Full chart for each level (not just in intervals)
- Enchanted Stone return values from melting high-level gear
💡 Final Takeaways
✔ Total cost to upgrade Epic +1 gear (15–40): 475,390 Enchanted Stones
✔ Costs ramp up significantly after Level 30
✔ Spider Boss = best source of stones
✔ Prioritize main team gear upgrades
✔ Stockpile now so you aren’t scrambling later
