In the high-stakes economy of the legendary MMORPG Knight Online, your character’s power is directly tied to the level of your gear. Whether you are running a rogue, warrior, priest, or mage, transforming raw weapons and armor into high-tier killing machines requires interacting with the infamous Magic Anvil in Moradon. At the very center of this high-risk progression system is a single, critically important item: the Blessed Upgrade Scroll, known universally by the player base simply as BUS.
Because upgrading item tiers can result in the complete and permanent destruction of your equipment, understanding exactly how the Blessed Item Upgrade Scroll works, where to farm it, and how the underlying probability math functions is essential for building wealth and dominating the battlefield.
What is the Blessed Item Upgrade Scroll?
The Blessed Item Upgrade Scroll is a premium-tier consummative item designed to enhance High-Class and Unique grade items within Knight Online. Unlike low or middle-class upgrade scrolls which carry severe level limitations and lower base success probabilities, the BUS is engineered to offer maximum success rates when advancing items to $+3, +7,$ or the coveted $+8$ thresholds.
While it does not protect your item from breaking if an upgrade fails at higher levels, it provides the fundamental mathematical baseline required to process high-class gear safely through early enhancement tiers. The item is so critical to the game’s economy that server currency valuation (Noah) is often measured directly against the buying and selling power of market-traded BUS packs.

When to use a Blessed Upgrade Scroll in Knight Online?
In Knight Online, a Blessed Upgrade Scroll (BUS) should be used from level $+2$ onwards for High-Class items, as it ensures a 100% success rate up to $+3$. For Middle-Class items, it is optimal to switch to a BUS after reaching $+7$ to maximize transition percentages into higher tier classifications.
Blessed Upgrade Scroll Drops: Nerden Düşer? (Where to Farm BUS)
For thousands of global players, particularly across the massive Turkish player base, the most common questions asked on forums are blessed item upgrade scroll nerden düşer and knight blessed upgrade scroll nereden çıkar. Because buying scrolls in bulk from merchants drains millions of Noah, setting up an efficient farming loop is the best way to fund your gear progression.
The absolute best locations and monsters to target for farming BUS include:
1. Ronark Land (The Colony Zone / CZ)
The high-risk PvP zone offers the highest drop-rate percentages for upgrade scrolls to incentivize faction warfare.
- Apostle of Flames (AOF) & Apostle of Piercing Cold (AOC): These high-level elemental monsters are prime targets for coordinated parties. They boast an optimized drop table for high-class scrolls and elemental scrolls.
- Hobgoblins: Located in designated camp zones within Ronark Land, Hobgoblins are heavily farmed because they drop both a steady stream of Noah and a relatively consistent supply of Blessed Upgrade Scrolls.
- Deruvish and Apostle Variants: Standard grinding spots that provide steady mid-tier drop rates.
2. The Abyss Dungeon (Delos)
Deep within the Abyss Dungeon, high-tier floors feature monsters with dense drop tables. Grinding on floors containing Shadows or Hell Hounds can yield rare BUS drops alongside valuable abyss gems.
3. Early Game Mobs (Low Probability)
While highly inefficient for high-level players, low-tier monsters in Luferson Castle or El Morad Castle like Lycan, Lupus, and Dark Eyes have a micro-percentage chance to drop a BUS. This is rarely done intentionally and is considered a lucky bonus during early-level training phases.
4. Direct NPC Purchase
If farming random number generators (RNG) is wearing you down, you can purchase Blessed Upgrade Scrolls directly from NPC Charon in Moradon. Located right next to the Magic Anvil, Charon sells them for a static price of 2,400,000 Noah (which can be slightly reduced depending on your clan’s castle control tax rate).
Magic Anvil Upgrade Success Rates with BUS
Upgrading in Knight Online is a strict numbers game governed by server-side probability algorithms. When using a standard Blessed Upgrade Scroll on a standard High-Class weapon (such as a Raptor, Shard, or Iron Bow), the baseline success percentages scale aggressively downward.
Below is an analytical breakdown of the approximate success rates at the Magic Anvil:
| Upgrade Progression | Base BUS Success Rate | Success Rate with Trina’s Piece |
|---|---|---|
| $+1 \rightarrow +2$ | 100% | 100% |
| $+2 \rightarrow +3$ | 100% | 100% |
| $+3 \rightarrow +4$ | ~70% | ~100% |
| $+4 \rightarrow +5$ | ~60% | ~90% |
| $+5 \rightarrow +6$ | ~40% | ~70% |
| $+6 \rightarrow +7$ | ~20% | ~50% |
| $+7 \rightarrow +8$ | ~5% | ~15% |
| $+8 \rightarrow +9$ | ~1% | ~3% |
Note: These figures reflect baseline estimates observed across retail server environments. Unique items and accessories utilize entirely independent progression structures.
Advanced Upgrading Strategies: Debunking the “Item Burning” Myth
Walk up to the Moradon anvil on any active server, and you will see dozens of players rapidly throwing low-tier items like $+7$ Wood Staffs or $+7$ Leather Armor into the anvil to intentionally destroy (“burn”) them before clicking their main weapon with a BUS.
The community superstition dictates that “burning” items clears out the failure states in the random number generator seed, opening up a “success window” for your expensive item. Mathematically, the game engine processes every single scroll click as an isolated server-side calculation. Item burning does not mathematically alter the drop or success percentage of the next item.
However, serious players who farm Ronark Land for hours often use data logs to track their long-term drop percentages and anvil successes. If you are keeping a detailed tracking log, protect your market data by learning how to password protect an Excel spreadsheet so rival clan members don’t steal your private upgrade analytics.
Unique Items and the Rebirth System
When handling highest-tier gear, the upgrade path branches into specialized mechanics:
Unique Weapon Upgrades
If you obtain a clean Unique item (such as a Chitin Shield or an Iron Necklace), you cannot immediately apply a standard Blessed Upgrade Scroll if the item is still sealed or lacks elemental alignment. You must first apply a Blessed Elemental Scroll (BES) to imbue the item with poison, lightning, flame, or glacier attributes before the standard BUS progression path unlocks at the anvil.
The Rebirth (Reverse) Scroll System
To mitigate the absolute devastation of losing a weapon on a failed $+7 \rightarrow +8$ click, many players convert their items into the Rebirth System. By applying a Reverse Scroll to a $+7$ High-Class item, it transforms into a $+1$ Rebirth item (complete with a glowing particle effect).
From there, you use Blessed Upgrade Scrolls (Rebirth) to advance the item in steady increments ($+1 \rightarrow +2 \rightarrow +3$, etc.). Each successful rebirth step adds minor stat bonuses equivalent to fractional standard tiers, offering a much more controlled, visual, and stable alternative to risky raw anvil runs.
