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.

🔥 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
