Enchantment Stone Success Rate Info

As promised ...

So there have been some questions and complaints etc on enchanting items so here I am with the breakdown.

The Code for the Enchant Service:

Code:

	public static boolean enchantItem(Player player, Item parentItem, Item targetItem)
	{
		int enchantStoneLevel = parentItem.getItemTemplate().getLevel();
		int targetItemLevel = targetItem.getItemTemplate().getLevel();

		if(targetItemLevel > enchantStoneLevel)
			return false;

		int qualityCap = 0;

		ItemQuality quality = targetItem.getItemTemplate().getItemQuality();

		switch(quality)
		{
			case COMMON:
			case JUNK:
				qualityCap = 0;
				break;
			case RARE:
				qualityCap = 5;
				break;
			case LEGEND:
			case MYTHIC:
				qualityCap = 10;
				break;
			case EPIC:
			case UNIQUE:
				qualityCap = 15;
				break;
		}

		int success = 50;

		int levelDiff = enchantStoneLevel - targetItemLevel;

		int extraSuccess = levelDiff - qualityCap;
		if(extraSuccess > 0)
		{
			success += extraSuccess * 5;
		}

		if(success >= 95)
			success = 95;

		boolean result = false;

		if(Rnd.get(0, 100) < success)
			result = true;

		int currentEnchant = targetItem.getEnchantLevel();

		if(!result)
		{
			// Retail: http://powerwiki.na.aiononline.com/aion/Patch+Notes:+1.9.0.1
			// When socketing fails at +11~+15, the value falls back to +10.
			if (currentEnchant > 10)
				currentEnchant = 10;
			else if (currentEnchant > 0)
				currentEnchant -= 1;
		}
		else
		{
			// Items that are Fabled or Eternal can get up to +15.
			ItemQuality targetQuality = targetItem.getItemTemplate().getItemQuality();
			if (targetQuality == ItemQuality.UNIQUE || targetQuality == ItemQuality.EPIC)
			{
				if (currentEnchant < 15)
					currentEnchant += 1;
			}
			else
			{
				if (currentEnchant < 10)
					currentEnchant += 1;
			}
		}

		if(targetItem.isEquipped())
			onItemUnequip(player, targetItem);

		targetItem.setEnchantLevel(currentEnchant);

		if(targetItem.isEquipped())
			onItemEquip(player, targetItem);

		PacketSendUtility.sendPacket(player, new SM_UPDATE_ITEM(targetItem));

		if(targetItem.isEquipped())
			player.getEquipment().setPersistentState(PersistentState.UPDATE_REQUIRED);
		else
			player.getInventory().setPersistentState(PersistentState.UPDATE_REQUIRED);

		if(result)
		{
			PacketSendUtility.sendPacket(player, SM_SYSTEM_MESSAGE.STR_ENCHANT_ITEM_SUCCEED(new DescriptionId(Integer
				.parseInt(targetItem.getName()))));
		}
		else
		{
			PacketSendUtility.sendPacket(player, SM_SYSTEM_MESSAGE.STR_ENCHANT_ITEM_FAILED(new DescriptionId(Integer
				.parseInt(targetItem.getName()))));
		}
		player.getInventory().removeFromBagByObjectId(parentItem.getObjectId(), 1);

		return result;
	}

The codes off the latest build which is 1.9 but not much has changed except the inclusion of +11-15.

I had to do some digging and extract a 1.5 item.pak and convert the binary xml files into a readable format but here we go.

The Break Down:

-Base Success Rate is 50%
-Enchant Rate is capped at 95% success.
-Epic (Eternal) items like Tahabata (Orange Items) Get a bonus to success rate because they are not capped.
-Unique (Fabled) items like Anuhart (Gold) are capped and get a lower success rate.
-Enchant Stones with Level < Item Level Always Fail

Success rate is determined by:

Orange Items:

Base Success Rate = 50%

Quality Cap Epic/Eternal = 0

1. Extra Success = (Enchant Stone Level - Item Level) - Quality Cap
2. If Extra Success is > 0 then Success Rate = Extra Success * 5 + Base Success Rate

If there is no bonus (Extra Success) then the default, 50%, is used.

ex. Tahabata using a level 50 stone
1. (50-50)-0 = 0
2. Extra Success is 0 so the Success Rate is 50%

ex. Tahabata using a level 70 stone
1. (70-50)-0 = 20
2. Extra Success is over 0 so Success Rate = (20*5)+Base Success = 150%

It's capped at 95% because it's over.

How do you take advantage of this you ask? Well Since the Base is 50% and Enchant Level - Target Level is basically your bonus since there is no cap on orange items you can figure that all Enchant Stones between level 60 to 70 will give you a 95% success rate. It's completely random and they all have the same success rate so theres no arguing.

Gold Items:

Base Success Rate = 50%

Quality Cap Unique/Fabled = 15

ex. Anuhart using a level 50 stone
1. (50-50)-15 = -15
2. Extra Success is less than 0 so the Success Rate is 50%

ex. Anuhart using a level 70 stone
1. (70-50)-15 = 5
2. Extra Success is over 0 so Success Rate = (5*5)+Base Success = 75%

69 Stones would give 70%
68 Stones would give 65%
67 Stones would give 60%
66 Stones would give 55%

Level 50 to 65 stones give you a 50% Success Rate.

Level 100 Stones would give you a 95% rate since it's capped.

Any questions?

Thank you for flying zp airlines.

very helpful guide

 

looks good :O

 

Great info.

Just a question though, if the percentage cap is at 95% for L100 stones...then why do we even have L150 stones available for donation if it does us no better than the L100 stones? lol

 

Good question. =p

Don't know really, they were left over from retail I'm sure. They probably make a difference there. Whoever was adding them to the store probably didn;t know there was a difference or how the enchant calculations are made.

It would be easy enough to set successrate to 100% bypassing the cap for 150 stones so you get a guaranteed level.

That would make the most sense to me.

Thanks for this, it really ends some speculation that people have been saying.

 

I dont know but atleast at Gamez I feel like I have failed too many times with lvl70 enchanment stone to be claimed its 95%, that would mean to fail 1 of 20 tries only.

 

Same. I fail with L70 stones about as much as I fail with L50 stones /:

 

L70 i use em when my weapon or armors+ reach +8 or to +9 and it came up success to +10...upgrading 1-8 i only use L50-60+ enchanment stones... and it works in me..got of +10 armor and weapons.. just be patience during upgrading... :d:lol:

 

It's all about luck sometimes... but if you keep trying, it should be +10 eventually

 

It would also help if the RNG wasn't pure evil D:

 

People have told me not to do it one after another. I heard from another guide to do one stone then wait about 5-10 minutes and then try another one and you will almost always suceed. I have yet to try this myself and of course you will still need higher level stones, but it is something to look into.

 

lol its evil when you have lvl 70 stones for lvl 55 gear =3

 

I didn't see any mention of the difference having a lvl of enchantment already on an item makes. From what I've seen the higher the previous enchantment lvl the less likely you are to succeed.

Additionally anything below lvl 60 never seems to work on anuhart, though I haven't done excessive amounts of enchantment.

 

Nope has nothing to do with it. It's all based off the rarity of the gear and the level difference between the gear and the enchant stone. The success rate is always the same for the same item and level enchant stone regardless of socketing or current level.

Anything below level 65 only gives you a 50% chance when enchanting gold stuff like anuhart. So you basically just go up and down and it takes forever to get to +10.

On Average using lvl 67-70 stones it takes about 15-20 to get anuhart to +10 from 0. Seems about right with a 55 to 75% success rate.

You have to look at the bigger picture. There will be lucky times and unlucky times and you may not really see the average unless your doing a lot of enchanting.

I bet. With level 70 stones level 55 gold gear would only have a 50% success rate. The upside of that is you won't need to use level 70 stones. The minimum success rate is 50%. So you could use level 55 stones, anything higher level than the item, and get the same 50% success rate.

It becomes more about just getting a good streak or streaks back to back to get it to 10. With a 50% rate you could use a 100 stones and still end of at 0. :lol:

It can be frustrating but you just have to be consistent and persevere.

how can we use that code..?? can som1 teach me..?? thanks

 

sry for bringing this thread back from the dead.
Just wanted to know if anyone else notice the rates being told here don't really make sense? i've been using around 15 lvl 70 enchant stones to try and get my Taha spear to +15 (started using lvl 70 stones when my spear reached +10) without much luck, out of the 15 only 3-4 worked, i even had 5 of them fail in a ROW. (yes, item went back to +10 from failing at +11, then went downhill to 9,8,7 and then 6 all with lvl 70 stones.

my legion mates found it true as well, for some weird reason, we all mostly always failed while using lvl 65+ stones and got most lvl 55-59 stones to work.

Anyway, is there anyway to be sure the rates are actually 95% for lvl 60-70 stones? i dont feel like wasting 30+ of em only to find my spear back to +6-7 again -.-;

 

The rates never were 95% for taha on lv70 stones, nor are they supposed to be. For taha, I believe the base rate is 65% on a lv70 stone. Use lesser enhancement supplements to help.

 

oh wow, this game uses Java language???
Good guide. thx ^^
