The 3 Offensive Gemstones (@ a 25% reduced price) |

Question :

**Which of the 3 offensive gemstones is the best to add ?**

I hope to answer this question in this post. Let me first say that a polished offensive gemstone normally costs 6400 Andermant and not 4800 like in the image above. But today gemstones were on a 25% reduced price, that's why they are labelled as 4800 Andermant.

I will try to answer this question by adding 3 polished offensive gemstones (ruby, onyx and sapphire) at a time to my character and calculate total damage for each gemstone.

In that way we can see which gemstone has to most influence on total damage done. But first let us make a formula to calculate that total damage done.

**Formula for total damage per second done**Character values with no gemstones |

__1) Base Damage :__Gemstone -> Ruby

This is the damage done with 1 stroke. It has a minimum and maximum value. So you damage done with a single stroke can vary between those 2 value. For my calculation I use

**average damage**which is the average of the minimum and maximum value.

**avg dmg = (min dmg + max dmg ) / 2**

__2) Attack Speed :__Gemstone -> Sapphire

The attack speed value gives the number of strokes per second. When we combine the avg dmg (which is the damage on average done by 1 stroke) with the attack speed (number of strokes per second) we get the damage per second. In formula it looks like this :

**avg dmg/s = [**

**(min dmg + max dmg ) / 2] * Attack Speed**

__3) Critical Hit Rate (__Gemstone -> Onyx

**CHR**) :While damage and attack speed is pretty straightforward, CHR maybe needs some explanation.

To explain this we introduce the term 'Critical Hit'.

A critical hit is a hit where the normal damage is multiplied by the critical damage.The Chance of delivering a critical hit is given by the critical hit rate.

**CD**) is 200%. This means that in 24.90% a hits of mine does 200% of my avg damage.

This also means that in 100% - 24.90% = 75.1% I deliver a normal hit. This 75.1% I refer to as Normal Hit Rate (

**NHR**).

**Calculating for total damage per second done :**

__part A : NHR__

**(100% - CHR) * [(min dmg + max dmg ) / 2] * Attack Speed**

__part B : CHR__

**CHR * [(min dmg + max dmg ) / 2] * Attack Speed * CD**

__Total formula = part A + part B__

**{(100% - CHR) * [(min dmg + max dmg ) / 2] * Attack Speed} + [CHR * ((min dmg + max dmg ) / 2) * Attack Speed * CD]**

**Explanation.**Part A gives the average dmg/s for normal hits. Part B is the equation for a criticit hit. Mind that the critical damage is added in this part.

**Our Base Character**

As we calculate the dmg/s for our base character we get :

- {(100% - 24.9%) * [(317 + 375) / 2] * 1.18} + [24.9% * ((317 + 375) / 2 * 1.18 * 200%]

- (75.1% * 346 dmg * 1.18 attack/s) + (24.9% * 692 dmg * 1.18 attack/s)

- (306.61 + 203.32) dmg/s

- 509.93 dmg/s

Although my character has only 375 maximum damage per swing, it does almost 510 dmg per second. This is possible because it delivers more than 1 attack per second (1.18 to be precise) and because in 24.9% of the cases the damge done is dubble the normal damage.

**Offensive gemstones compared**Now that we have our formula for calculation dmg/s, we can compare the effect of adding different gemstones. As you can see in the image underneath, I added 3 polished gemstones (or a equivalent of that in case of the ruby) at a time.

Values for each gemstone |

In the table you can see the values for the different characters.

Calculations for different gemstone additions |

Adding 3 polished sapphire with a total of +15% attack speed seems to give you the most value for money. It raised the dmg/s from 510 tot 583, that's a raise of 71 dmg/s or 14%.

Adding for 19200 Andermant 3 polished Onyx gemstones raises you dmg/s with 'only' 32 points !! That's roughly half (read : -50%) of the effect of the sapphires.

The rubies or somewhat in between. But there is still a 22% difference between the effect of the sapphires and those of the rubies. Pretty significant imho.

**: Adding attack speed seems the best option if you want to inflict more damage. Adding CHV seems to be the worst choice.**

__Conclusion__

**Some remarks**1) CHR increases not linear. When you have an already high CHR, the effect of adding extra Onyx gemstones will be less than when you have a low CHR. I found the image underneath on the German Forum in this post.

CHR increase is not linear |

3) Some items (mainly weapons) have enchantments which increases damage or attack speed percentage wise. Adding gemstones of those enchantments will also increase the effect of that gemstone.

YOU HAVE DONE GREAT WORK WITH YOUR BLOG. VERY USEFULL FOR EVERYONE PLAYING DRAKENSANG. THANK YOU!

ReplyDelete"3) Some items (mainly weapons) have enchantments which increases damage or attack speed percentage wise. Adding gemstones of those enchantments will also increase the effect of that gemstone."

ReplyDeleteAFAIK, this only works with rubies in weapons that have % increased damage enchantments. I've tested the possibility of this with sapphires in a weapon that has % attack speed enchantments and it had no additional effect on the character's overall attack speed.

interesting, thanks for the info.

DeleteOne comment against adding (too many) sapphires. The extra speed is good if you use your basic attack (and some skills without cooldown, for example chain lightning as a mage). But a meteor or destruction spell is not affected by sapphires, as they won't be faster, while a ruby increases the damage for all skills and spells. Therefore I usually vote for ruby.

ReplyDeleteit is best to use both rubies and attack speed gems. thanks for the info, i will try to balance both gems.

Delete10 dmg stays 10 dmg wether you have 200 base dmg or 1500 base dmg. But adding sapphires increases your dmg per second according to your base dmg.

Delete5% increase of 1000 dmg/s is 50 dmg/s. It takes a lot of rubys to get that dmg/s increase.

Just use the formula to see what's best ;)

thanks.

Deletekk, thanks for the info, i am a ranger, so adding speed is no problem. i don't use supportive shills like bird of prey often, mostly those skills the attack speed gems affect. i am adding 50% attack speed to my alans bow(+ 16% attack speed) and extra 30 + damage gems to my focus crystal.

ReplyDeleteHey,

ReplyDeleteI`m ranger to, and i have legend bow with 1,43 speed in base (4 modificators of speed) and sapphires count with them. I have 2 sapphires (5% and 2,5%) and my end speed is 1,53 (i`m only 26lvl). But this modificator from bow is only working with sapphires (doesn't matter where you put it: 5% is in weapon decoration and 2,5% is in bow.

For example if you have +2.5% speed in other item (like wind arrow) then it will be only 2,5% added :)

I hope i helped.

thanks, that helped.

ReplyDeleteHi nice work but what is gone wneh the Cd changes for example my is 275%

ReplyDeleteIm the person who post: AnonymousAugust 18, 2014 at 1:09 AM

ReplyDeleteThis is easy to count. But it depends what is your base dmg. On lover base dmg is better to put rubys.

We can take 3 types of dmg (all will be avarage)

ADMG1 = 100

ADMG2 = 200

ADMG3 = 500

As - Your attack per second = 1

CD - Crit DMG = 275% (dosent matter how it is big it could be regular 200% because this value is constant for both ruby and sapphires)

What we gonna check:

DMG in one blow - HitDMG

Critt dmg in one blow - CHitDMG

Normal dmg per second- NDMG/s

Critt dmg per second - CDMG/s

1) ADMG1 = 100

HitDMG1 = ADMG1 = 100 = 100dmg

CHitDMG1 = ADMG1 * CD = 100 * 2,75 = 275dmg

NDMG/s 1 = ADMG1 *As = 100* 1 = 100dmg

CDMG/s 1 = ADMG1 * As *CD = 100 * 1 * 2,75 = 275dmg

After one RUBY (+10dmg)

HitDMG1 = (ADMG1 + 10) = 100 +10 = 110dmg

CHitDMG1 = (ADMG1 +10) * CD = (100+10)*2,75 = 302,5dmg

NDMG/s 1 = (ADMG1 + 10) * As = (100+10)*1=110dmg

CDMG/s 1 = (ADMG1 + 10) * As * CD = (100+10)*1*2,75 =302,5dmg

After one sapphire (5%) ("As" will be 1,05)

HitDMG1 = ADMG1 = 100dmg

CHitDMG1 = ADMG1* CD = 100 * 2,75 = 275dmg

NDMG/s 1 = ADMG1 * As = 100*1,05= 105dmg

CDMG/s 1 = ADMG1 * As * CD = 100*1,05*2,75 = 288,75dmg

So for 100 Avarage DMG Ruby is better choice (only if you wanna check the DMG value)

2) ADMG2 = 200

HitDMG2 = ADMG2 = 200 = 200dmg

CHitDMG2 = ADMG2 * CD = 200 * 2,75 = 550dmg

NDMG/s 2 = ADMG2 *As = 200* 1 = 200dmg

CDMG/s 2 = ADMG2 * As *CD = 200 * 1 * 2,75 = 550dmg

After one RUBY (+10dmg)

HitDMG2 = (ADMG2 + 10) = 200 +10 = 210dmg

CHitDMG2 = (ADMG2 +10) * CD = (200+10)*2,75 = 577.5dmg

NDMG/s 2 = (ADMG2 + 10) * As = (200+10)*1=210dmg

CDMG/s 2 = (ADMG2 + 10) * As * CD = (200+10)*1*2,75 =577.5dmg

After one sapphire (5%) ("As" will be 1,05)

HitDMG2 = ADMG2 = 200dmg

CHitDMG2 = ADMG2* CD = 200 * 2,75 = 550dmg

NDMG/s 2 = ADMG2 * As = 200*1,05= 210dmg

CDMG/s 2 = ADMG2 * As * CD = 200*1,05*2,75 = 577.5dmg

3) ADMG3 = 500

HitDMG3 = ADMG3 = 500 = 500dmg

CHitDMG3 = ADMG3 * CD = 500 * 2,75 = 1375dmg

NDMG/s 3 = ADMG3 *As = 500* 1 = 500dmg

CDMG/s 3 = ADMG3 * As *CD = 500 * 1 * 2,75 = 1375dmg

After one RUBY (+10dmg)

HitDMG3 = (ADMG3 + 10) = 500 +10 = 510dmg

CHitDMG3 = (ADMG3 +10) * CD = (500+10)*2,75 = 1402,5dmg

NDMG/s 3 = (ADMG3 + 10) * As = (500+10)*1=510dmg

CDMG/s 3 = (ADMG3 + 10) * As * CD = (500+10)*1*2,75 =1402,5dmg

After one sapphire (5%) ("As" will be 1,05)

HitDMG3 = ADMG3 = 500dmg

CHitDMG3 = ADMG3* CD = 500 * 2,75 = 1375dmg

NDMG/s 3 = ADMG3 * As = 500*1,05= 525dmg

CDMG/s 3 = ADMG3 * As * CD = 100*1,05*2,75 = 1443,5dmg

Calculation was for 100%dmg skill but with skills with 125% (like precision shoot) the difference will be bigger.

Of course if we have weapon with 1,43 speed in base (like i said in earlier post) than sapphires will give me much more than rubbys. ( and opposite when we have %dmg modificators)

I hope i helped.

Ranger: Gatrol (if someone wanna meet me in game, server Grimmag)

thanks for the info, sorry i was busy for the few days, i am sticking with the 1st part with ADMG1 = 100 damage. my 1,39 % attack speed with give extra damage since i got over 200% critical hit value and damage. Once again thanks for the info.

ReplyDeleteHey, all again (this is Gatrol)... i don't know if anyone is reading this ( i must give some corrections to my earlier posts) but i have karabossa set now. This set give me 11,1% speed and with my speed bow, 1,43 + one 5% sapphire and with this set a have speed 1,66.

ReplyDeleteSo i must change my view of end speed.

Bonuses from other items (like karabossa set) are multiplied by my bow speed :)

Gatrol

Awesome, congrats! Keep up the great work

Deletei got 2.30 atacks/s in pvp
