BDO Enhancement is the process of upgrading gear to increase its power. The levels of Enhancement go from +1 to +20. Most gear and accessories in Black Desert Online can be enhanced, as long as you have enhancement materials on hand and a handful of luck.
Enhancement Levels:
- PEN (V) +20
- TET (IV) +19
- TRI (III) +18
- DUO (II) +17
- PRI (I) +16
- +15 to +1
Enhancing is sometimes called by the traditional name of “Enchanting”.

…you’ve got to ask yourself one question: ‘Do I feel lucky?’ Well, do ya, punk?” –
RNG Me Away!
Enhancement is very RNG heavy. Players frequently flood chat and video channels with how unfair the Enhancement system has been to them. Unsafe Enhancement is a gamble, especially when you approach +13 and above. TET and +15 begin with a mere 2% chance at succeeding. PEN? Forget about it! I won’t depress you with the numbers. 🙂
It makes me wonder how many players have quit BDO over this sometimes infuriating mechanic.
There are a few oddballs who actually enjoy Enhancement… but never mind the craziest. It’s safest to avoid them, and any mention of them actually. They might be reading this right now *gulp*.
What about Safe Enhancement?
Black Desert has implemented some safe ways to to achieve Enhancement like Guaranteed PEN, Force-Enhance, Caphras Stones, Cron Stones, and Magical Black Stones, but these options may seem overly time consuming and expensive when one dreams of a “lucky” one touch TET, etc. Many people forgo “Safe Enhancement” options. To complicate matters, there are fewer safe options for the best gear. This leads to frustration upon frustration for the unlucky and the heights of joy for the lucky few…
Which path will be yours?
Enhancement Basics
Enhancement Requirements
You must have completed the quest called [Awakening] Traces of Edana. This quest is not very far into the first Main quest chain given by the Black Spirit. Some Enhancing items also have a level 30 requirement in order to use.
You will also need plenty of Enhancement items. A typical TET enhancement session can run 1000+ Black Stones. 300+ Memory Fragments and much more. I will detail all the enhancement items below.
Enhancement Window
To view the Enhancement interface, talk to the Black Spirit by pressing (,) key. Click the “Enhancement” button.

An easier way is to just right click the Enhancement item consumable, such as a Black Stone.
Failstack Basics
A Failstack is a player term for Enhancement Chance. It is an indicator of the times you have continuously failed at enhancement. The more times you fail enhancement in a row, the more failstacks you obtain. The more failstacks you have, the greater your chances to succeed at the current upgrade.
Additional Enhancement Chance +
Valks’ Cry +
Permanent Enhancement Chance (Hidden)
= TOTAL FAILSTACK
The total Failstack is the “Current Enhancement Chance” number in the Enhancement window.
Failstack Building Tip:
- If available, check the “Durability” option, which increases chances of gaining a failstack. Durability option often doubles the difficulty of enhancement.

Max Durability & Enhancement Failure
Failstacks are a good thing, but they do cost you! Every time you fail Enhancement, you lose at least 5 Max Durability on the item you are trying to upgrade, plus your Enhancement mats.
For higher level gear enhancement of DUO+, you can actually downgrade the item. So a DUO could become a PRI on failure. (Unless you use Cron Stones.)
Accessories have different failure costs. Both accessories are destroyed upon failure. (Cron Stones protect from destruction, but the accessory may downgrade instead.)
Max Durability is repaired by visiting the Blacksmith and clicking Repair > Recover Max Dur.
Max Durability can be repaired by destroying another of the same kind.
For expensive repairs, like boss gear, you can use Memory Fragments (and optionally a Pearl item called Artisan’s Memory with it).
In unsafe Enhancement, the Max Durability lost depends upon the enhancement consumable used.
Black Stones: -5 Max Durability.
Concentrated Black Stones: -10 Max Durability
Total Cost of Failstack = Black Stones + identical gear for repair or Memory Fragments.
Safe Enhancement methods have much higher Max Durability repair costs.

Force-Enhance
“Force-Enhance” gives a 100% Enhancement Chance. This is only available for certain gear and items. It costs a set amount of Max Durability and Black Stones. For some gear, you can only Force-Enhance up to TRI. For this reason, there are some players who disagree with using it because they say you need Failstacks anyway for TET and PEN. But, for other players, who don’t like the gambling aspect of Enhancement, it’s an option.
After gear reaches TRI, you can get 100% Enhancement Chance by using Caphras Stones, which are a rare drop from higher level mobs and given via daily quests. Caphras quantities required for this Safe Enhancement option are high though. Please see our Caphras Guide for details.

Enhancement Options: Durability vs Enhance
Enhancement Option – Durability: Selecting this option decreases the Max Durability lost on failures. It also increases the difficulty of enhancing.
This is used to increase your chances of gaining another Failstack.
However, if you are a new player or don’t currently want a Failstack, select the “Enhance” option instead.
Enhancement Option – Enhance: Selecting this option before Enhancement doubles the Enhancement Chance, so that gear is easier to Enhance.
Use this option if you are not interested in building Failstacks for higher level Enhancements.

Cron Stones
When you attempt to enhance a DUO or greater level item, there is a chance that it will downgrade its level instead of gaining a level. So your DUO could drop to a PRI. Cron Stones are used to protect an item from downgrading a level after a failed Enhancement attempt.
Accessories are treated differently. Cron Stones protect them from being destroyed, but accessories have a 40% chance to loose 1 level.
Obtaining Cron Stones:
- Extracting a Pearl Costume at a Blacksmith
- 2 million silver each at a Blacksmith
- others ways detailed in our Cron Stone Guide
Purchasing Cron Stones at the NPC is an expensive option. It’s cheaper to let a DUO item downgrade to PRI and then sell the PRI and purchase another DUO off the Marketplace to continue attempting a TRI. (Prices and availability change all the time. Be sure to check the quantity and price of enhanced gear on Central Market.)

Reform Stones
Ultimate Weapon/Armor Reform Stone
100% enhancement chance: “Ultimate”
Ultimate Reform Stone will upgrade green or blue grade armor to yellow grade 100% of the time.
Processing Recipe:
Heating: x10 Grade 3 Reform Stone + x1 Black Crystal Shard

0% enhancement chance: “Ultimate”
20% enhancement chance: “of Temptation”
30% enhancement chance: “of Destruction”
30% enhancement chance: “of Crimson Flame”
20% enhancement chance: green grade
Grade 2 Weapon/Armor Reform Stone

Max Durability Cost: 30

Caphras Stone
Weapons and Gear that are TRI to PEN have up to 20 Caphras levels. They start at 0 level and gain experience towards the next level by feeding them Caphras Stones. Every level adds attack or defense stats to your character’s sheet stats, when equipped.
To start Enhancement with Caphras, visit Black Spirit > Enhancement > “Caphras Enhancement”.

100% Enhancement Chance via Caphras Stones:
When your gear reaches level 20, you can increase its Enhancement level by 1. Make sure your item is at 100% Max Durability and click the ‘Upgrade Enhancement’ button.
NOTE: 100% ‘Upgrade Enhancement’ will reduce Max Durability to 0 and reset the Caphras Level
What happens if I want to stop early?
If you get tired of waiting on your gear’s Caphras level to improve, you can still attempt to Enhance the traditional way via Concentrated Magic Stones and luck.
- Enhancement Failure with Caphras EXP: if your enhancement level drops, only 50% of the item’s EXP will be kept.
- Enhancement Success with Caphras EXP: only 10% of the item’s EXP will be carried forward to the next level
- Enhancement Failure with Crons: If you fail enhancement using Cron Stones, 5% of the Cron Stones will be converted into Caphras exp.
To view Caphras Stone charts and learn how to craft and obtain Caphras, please visit our Caphras Stone Guide.
Memory Fragments
Every player will eventually require hundreds of Memory Fragments, which repair the Max Durability of expensive boss gear. Max Durability is lost as gear is enhanced into greater power. Cheap gear can be repaired using identical cheap gear. But, using boss gear to repair boss gear would get extremely expensive. Memory Fragments can be used instead and are far cheaper.
Memory Fragment Durability Recovery Rates:
- White Grade: Recovers 10 Max Durability
- Green Grade: Recovers 5 Max Durability
- Blue Grade: Recovers 2 Max Durability
- Yellow Grade: Recovers 1 Max Durability
- Orange Grade: Recovers 1 Max Durability
NOTE: Amount of Durability increases x5 if used withArtisan’s Memory, purchased from the Pearl Shop.

Artisan’s Memory (P2W & Loyalty Reward)
Artisan’s Memory turns 1 Memory Fragment into 5. So it will repair 5 Max Durability of your boss gear instead of just one, if it is yellow grade.
Artisan’s Memory Full Price:
- Quantity 1: 50 Pearls
- Quantity 10: 450 Pearls
- Quantity 100: 4000 Pearls
These do go on sale periodically and there are sometimes coupons available.

Players also have the option of logging in every day for 4 days. This will give you 800 Loyalties, which is enough to purchase 1 Artisan’s Memory from the Loyalty shop.
Do titles like PRI DUO… What? give a slight advantage or is this just my superstition?
Hello 🙂 It’s a little confusing isn’t it? In order of strongest to weakest: PEN > TET > TRI > DUO > PRI > +15. I’m not sure where those terms came from. PEN is a well known to be an acronym for “Probability, Electric Strength, Number of Life Cycles” Now it makes perfect sense!! 🙂
Thanks for replying, didn’t think I would get an answer. Anyway, what I was referring to were the world titles like for succeeding enchantments we get; Enhance-ologist, Sparkle Sparkle, Steel-Winged, PRI DUO… What?, ect,. and the titles for failures/failstacks; Black Stone Illusionist, AAAAAAAAAH, Doubting the Black Spirit, Black Stone Donator, ect.
Does it boost my chances if I have a title on my character while I attempt my enhancements or when I’m trying to build failstacks? Thanks again for your reply.
LOL! Oh, I misread that one. 🙂 I’ve heard this from time to time, but I think it’s tinfoil. Could be true, but I don’t know of anyone that’s actually published studies on it. Would be fun if it were true. 🙂
Actually those are Greek prefixes (duo, tri, tetra, penta-2,3,4,5) that are used in many languages to denote the multiplicity of something (in geometry the number of segments). PRI should be MON though (for mono) since primo means something else (first, in Latin not Greek).
LOL! Someone here has a few cells in the attic! Thanks for the tidbits. It’s interesting. 🙂
Completely out of the blue but had to do it. PRI for PRImary
PRI – PRImary
DUO – common word for ‘two’
TRI – common prefix for ‘three’
TET – TETra – common prefix for ‘four’
PEN – PENta – common prefix for ‘five’
I quit BDO because of its miserable enhancement system, spent 2 straight actual years, trying to TET an offhand, with properly sized failstacks, Thousands of hours of grinding, billions in game currency, only to regress backwards to DUO dozens of times.
no matter how good you explain it this RNG Train of misery is still misery
Weird! I went to my first World Boss yesterday and the Kzarka weapon dropped. I had some mats in the storage so quickly tapped it up to +15, then after some minor back and forth pushed to TET on my first try, and PEN on my first try.
Wow… what a stinking pile of bs is this whole enhancement system.
Thanks for compiling this very informative article, now I can sell all those Caphras and Memories as soon as they drop.
One question though, what would be the cap for those people that decide against riding on this train of misery?
You build failstacks to 200+ if you want PEN accessories depending on the price probably 220+ for PEN blackstar more than that but its pretty RNG, my first probably last PEN was 217 stack
