Rarity Forge System

Upgrade your equipment with mystical power.

Welcome to the Rarity Upgrade system. Here you can enhance your equipment by adding powerful random attributes based on the item's Tier and Rarity level.

1. How to Start
The Forge The Forging System is located in the NPC Zone. You can travel there from any Temple in the game.
How to use? You can use the stationary forge in the zone or buy a Portable Forge Tool from the NPCs to forge anywhere. Simply right-click the tool to start.
The Core Gameplay Loop

If you are new, follow these simple steps to power up:

  1. Collect Orbs: Hunt monsters to find mystical Rarity Orbs.
  2. Open the Forge: Get a Forge Tool from NPC Pipiro and right-click it.
  3. Upgrade: Put your White (Normal) Item in the forge with the correct Orb.
  4. Perfect or Recycle: Use Clean Orbs to reroll stats, or Extractors to get orbs back.

2. Item Compatibility & Benefits
Eligible Items Most equipment is compatible if it has a Tier (1-4). This includes Swords, Axes, Clubs, Distance Weapons, Shields, Helmets, Armors, and Boots.
Ineligible Items The forge cannot process Stackable items, Containers (backpacks), Fluid containers (vials), Runes, or Rarity Orbs themselves.
Why Forge? Forged items are a game-changer. They grant stats you can't get anywhere else, like Mana/Health Regen, Attack Speed, and massive HP/MP boosts via Bonus Slots.

3. Meet the Orbs
Uncommon Orb The most common source of power. Used for basic Tier 1 equipment upgrades.
Rare Orb A step up in power, required for Tier 2 items.
Epic Orb Powerful and sought after. Required for Tier 3 equipment.
Legendary Orb The ultimate power. Only for the strongest Tier 4 items and bosses.

4. System Mechanics
Item Tiers Items are classified into 4 Tiers (1-4) based on power. Tiers determine costs and reward orbs.
Rarity Levels Items receive random attribute slots based on rarity:
  • Common: Base item.
  • Uncommon: 1 Bonus Slot
  • Rare: 2 Bonus Slots
  • Epic: 3 Bonus Slots
  • Legendary: 4 Bonus Slots

Common Questions (FAQ)
  • Q: What is an Orb Extractor?
    A: A tool to "recycle" forged items to recover Orbs. Using it always extracts the orbs and destroys the item.
  • Q: Do I keep my item after extracting?
    A: No. Extraction is 100% guaranteed to give you the Orbs, but the item is always destroyed in the process.
  • Q: Does the extractor break?
    A: Normal Extractor: Has a 50% chance to break. Perfect Extractor: It is permanent and never breaks.
  • Q: Is level 100 the cap?
    A: Yes, Mastery Level 100 is the current limit.
Pro Mastery Tips
  • Efficient Leveling: Use Tier 1 updates to level Mastery cheaply. Failures still give exp!
  • Success Cap: You can reach 100% success chance on lower tiers with high Mastery.
  • Risk Warning: Always use a Forge Protector for Legendary attempts (4% break risk).
  • Reroll vs Restart: Use Clean Orbs on high-rarity items instead of starting over.
