Upgrading weapons and armor in Knight Online is one of the most thrilling and risky aspects of the game. Every player knows the heartbreak of losing a hard-earned +7 weapon to a failed upgrade attempt. That's where Blessed Upgrade Scrolls become essential. These special scrolls protect your gear from destruction during upgrade attempts, making them invaluable for progressing your character safely. In this comprehensive guide, we'll cover everything you need to know about using Blessed Upgrade Scrolls effectively, including success rates, cost comparisons, and expert strategies to maximize your upgrades without breaking the bank.
What Is a Blessed Upgrade Scroll in Knight Online?
A Blessed Upgrade Scroll (often called "Blessed Scroll" or "BUS" by players) is a premium upgrade material in Knight Online that attempts to enhance your weapons or armor while providing critical protection. Unlike standard upgrade scrolls, Blessed Scrolls prevent your item from being destroyed if the upgrade fails.
The key difference is simple but crucial: when you fail an upgrade with a normal scroll at higher levels (+6 and above), your item can break permanently. With a Blessed Upgrade Scroll, your item is safe from destruction though it may downgrade by one level depending on the current enhancement level.
This protection makes Blessed Scrolls the go-to choice for expensive gear, high-level items, or when you're attempting risky upgrades beyond +6.
How Blessed Upgrade Scrolls Work
Understanding the mechanics behind Blessed Scrolls helps you make smarter upgrade decisions:
Success: Your item upgrades to the next level (e.g., +6 becomes +7). All stats increase accordingly, and you keep the scroll's protective benefit for future attempts.
Failure: This is where Blessed Scrolls shine. Depending on your current upgrade level:
- +0 to +6: Item remains at its current level (no downgrade, no destruction)
- +7 and above: Item downgrades by one level (e.g., +7 becomes +6)
- No destruction: Your item never breaks, regardless of upgrade level
The Process:
- Right-click the Blessed Upgrade Scroll in your inventory
- Left-click the weapon or armor you want to upgrade
- The system attempts the upgrade automatically
- Result appears instantly success (level up) or failure (safe or -1 level)
This protection mechanism makes Blessed Scrolls worth their premium cost, especially when attempting high-risk upgrades.
Blessed Upgrade Scroll Success Rates
Success rates decrease significantly as your item's enhancement level increases. Here's a realistic breakdown:
| Upgrade Level | Estimated Success Rate | Risk Level | Blessed Scroll Recommended? |
| +0 to +1 | ~95% | Very Low | No (use normal scrolls) |
| +1 to +2 | ~90% | Very Low | No (use normal scrolls) |
| +2 to +3 | ~85% | Low | No (use normal scrolls) |
| +3 to +4 | ~75% | Low | Optional |
| +4 to +5 | ~65% | Medium | Optional |
| +5 to +6 | ~50% | Medium | Recommended for expensive items |
| +6 to +7 | ~40% | High | Highly Recommended |
| +7 to +8 | ~30% | Very High | Essential |
| +8 to +9 | ~20% | Extreme | Essential |
| +9 to +10 | ~10% or less | Extreme | Essential |
Important Note: These rates vary slightly based on item type, server settings, and game updates. Always check current community resources for your specific server.
Blessed Scroll vs Normal Scroll Comparison
Choosing between scroll types depends on your upgrade level, budget, and risk tolerance:
| Factor | Normal Upgrade Scroll | Blessed Upgrade Scroll |
| Cost | Low (affordable for farming) | High (10-50x more expensive) |
| Item Protection | None (item breaks on fail at +6+) | Full protection (never breaks) |
| Best For | +0 to +5 upgrades | +6 to +10 upgrades |
| Failure Result (+0 to +5) | Item stays same level | Item stays same level |
| Failure Result (+6+) | ITEM DESTROYED | Downgrades -1 level |
| Recommended Use | Common items, low levels | Rare items, expensive gear, +6+ |
| Availability | Easy to obtain | Harder to farm, often bought |
When to Switch: Most experienced players use normal scrolls up to +5 or +6, then switch to Blessed Scrolls for all attempts beyond that threshold. For extremely rare or expensive items, some players use Blessed Scrolls from +4 onwards.
Best Time and Levels to Use Blessed Upgrade Scrolls
Strategic scroll usage saves millions of Noah (Knight Online currency) over time:
Low-Risk Zone (+0 to +5):
- Use normal scrolls exclusively unless the item is irreplaceable
- Success rates are reasonable, and failed attempts just waste scrolls, not items
- Save your Blessed Scrolls for later
Medium-Risk Zone (+5 to +6):
- Consider Knight Online Blessed Upgrade Scroll strategies for weapons worth over 100 million Noah
- For common items, normal scrolls still work
- This is the transition point for most players
High-Risk Zone (+6 to +8):
- Always use Blessed Scrolls
- Normal scrolls will destroy your item, erasing hours of farming
- The cost of Blessed Scrolls is cheaper than replacing broken items
Extreme-Risk Zone (+9 to +10):
- Blessed Scrolls are non-negotiable
- Success rates drop to 10-20%, meaning many attempts needed
- Budget dozens of scrolls before attempting
- Consider if the stat increase justifies the cost
Pro Timing Tip: Some players believe certain server times or days have better RNG. While unproven, attempting upgrades during off-peak hours when fewer players are online is a common superstition that some swear by.

Pro Tips to Maximize Upgrade Success
Veteran players use these strategies to minimize costs and maximize results:
Preparation Tips:
- Always have multiple scrolls before starting (never attempt with just one)
- Upgrade during stable server conditions (avoid lag)
- Clear inventory space for smooth transactions
- Have backup gear ready in case of downgrades
Common Mistakes to Avoid:
- Using normal scrolls on +6 or higher items (instant regret if it breaks)
- Attempting +9 or +10 without sufficient scroll budget
- Rage-upgrading after failures (this drains resources fast)
- Not comparing market prices before buying scrolls
- Upgrading items you don't actually need enhanced
Smart Strategies:
- Set a budget limit per item (stop if you exceed it)
- Calculate total cost: multiple Blessed Scrolls often cheaper than replacing a broken item
- Upgrade multiple items to +6 before pushing any to +7
- Join a guild to share upgrade material farming
- Sell +7 or +8 successes for profit, buy others' failures at discount
Risk Management:
- Never upgrade your only weapon without a backup
- Consider buying already-enhanced items instead of upgrading
- For +9 and +10, calculate if the stat increase justifies the cost
- Save scrolls during scarce periods when prices spike
The 3-Strike Rule: Many players follow this guideline: if you fail three consecutive Blessed Scroll attempts, take a break. Come back later with a fresh mindset rather than burning through your entire scroll supply in frustration.
Frequently Asked Questions (FAQs)
Does a Blessed Upgrade Scroll guarantee success?
No, Blessed Scrolls do not guarantee success. They have the same success rates as normal scrolls but protect your item from destruction on failure. Think of them as insurance, not a guaranteed upgrade.
Can Blessed Scrolls be used above +7 or +8?
Yes, absolutely. Blessed Scrolls work at all upgrade levels, from +0 to +10 (or higher depending on server caps). They become increasingly essential as you push toward +9 and +10 due to extremely low success rates at those levels.
Is it worth the cost?
For items at +6 and above, Blessed Scrolls are almost always worth it. A single broken +7 weapon worth 500 million Noah makes the cost of 5-10 Blessed Scrolls seem minor. Do the math: replacement cost vs scroll cost. Blessed Scrolls win every time for valuable gear.
Can I use Blessed Scrolls on armor and accessories?
Yes, Blessed Scrolls work on weapons, armor pieces (helm, chest, gloves, boots, pants), and in most servers, certain accessories. Check your specific server rules for restrictions.
What happens to my item's bonus stats if it downgrades?
When your item downgrades from +7 to +6 after a failed Blessed Scroll attempt, it loses the stat bonuses associated with +7 and reverts to +6 stats. However, the base item remains intact with all its original properties.
Conclusion: Upgrade Smart, Not Hard
Blessed Upgrade Scrolls are the safeguard every serious Knight Online player needs in their inventory. While they cost more than normal scrolls, the protection they provide against item destruction makes them essential for any upgrade attempt beyond +5, and absolutely mandatory for +6 and higher.
Remember these key takeaways:
- Always use Blessed Scrolls for +6 and above upgrades
- Calculate the cost vs replacement value before attempting risky upgrades
- Build a scroll budget before starting enhancement sessions
- Know when to stop—chasing +10 can drain resources fast
- Consider buying pre-enhanced items if scroll costs become prohibitive
Smart upgrading means balancing ambition with economics. A +7 weapon in your hands is better than a broken +6 dream. Plan your upgrades, stock your Blessed Scrolls, and may RNG smile upon your enhancement attempts!
