What is Item Upgrading?

Item Upgrading is a system that allows you to permanently increase an item's base stats using Pixels and Crystals. Each upgrade level increases the item's damage or armor by 5%, making it significantly more powerful. This equipment enhancement system provides permanent stat boosts.

How Upgrading Works

When you upgrade an item:

  • The item's upgrade level increases by 1
  • Damage and armor increases by 5% of the base value
  • Enchantments are preserved during upgrades

Stat Scaling Formula

Final Stat = Base Stat × Item Quality × (1 + upgrade level × 0.05)

Example:
Base Attack: 100
Item Quality: 1.5 (Epic)
Upgrade Level: 4
Final Attack = 100 × 1.5 × (1 + 4 × 0.05) = 100 × 1.5 × 1.2 = 180

Each upgrade level adds +5% multiplicative bonus. At upgrade level 10, your item has +50% more attack/armor! This stat scaling creates powerful equipment.

Item Upgrade Costs

Upgrading requires both Pixels and Crystals.

What Affects Costs?

Upgrade costs increase with:

  • Higher Item Rarity: Legendary and Artifact items cost significantly more to upgrade than Common items
  • Higher Item Level: Level 50 items cost more than level 10 items
  • Better Item Quality: Items with higher Quality percentage cost more
  • Higher Upgrade Level: Each successive upgrade becomes exponentially more expensive
  • Item Type: Different equipment slots have different base costs
Cost Scaling: Upgrade costs increase rapidly with each level. Plan your resources carefully before upgrading high-level items!

Max Upgrade Level

The maximum upgrade level you can achieve increases with your player level and ascension bonuses. Higher max levels allow for more powerful equipment enhancement.

Max Upgrade Level = 1 + AscensionEnchantingModifier + playerLevel / (15 × levelsPerRealLevel)

This means:

  • Base max level: 1
  • Ascension Perks can increase the cap (+1 from Enchanting perk)
  • Every 75 actual levels grants +1 max upgrade level
  • Post-prestige players use max level (301) instead of actual level

Upgrade Level Progression (Pre-Prestige)

Player Level Max Upgrade Level Total Stat Bonus
1-74 1 +5%
75-149 2 +10%
150-224 3 +15%
225-299 4 +20%
300-301 5 +25%
Post-Prestige Players: After your first Ascension, the game always uses max level (301) for this calculation, giving you max upgrade level 5 (or 6 with the Enchanting Ascension Perk). This means you can fully upgrade items immediately after ascending!

🎯 Conclusion

Item upgrading permanently increases your equipment's power through multiplicative stat bonuses. Each upgrade level provides a 5% boost, creating significant power gains for fully upgraded gear.

Remember these key principles:

  • 5% Per Level: Each upgrade level adds a 5% multiplicative bonus to damage or armor
  • Enchantments Preserved: Upgrading never removes enchantments or item properties
  • Max Level Scales: Your maximum upgrade level increases with player level and ascensions

Choose your upgrade strategy: either upgrade gear you won't replace for a while (and upgrade them heavily), or spread upgrades across all equipment to maximize stat gains versus cost. With this upgrading guide, you're ready to maximize your equipment's potential!
