Damage increase and overall calculations

[yhaguen]

Hey all,

As many have questions about how Damage Increase works and how final Damage Calculations on your target is applied, I summarized information here. This guide is about close and range weapons, and weapons only.

Everything can be found in UO guide here: www.uoguide.com/Damage_Increase & www.uoguide.com/Damage_Calculations
I'll reuse this material and apply it to Traditions World.


1/ Damage Increase:

This modifier is split on 2 different parts: The Items bonuses capped to 100% plus the Skills and Stats bonuses capped to 200%. All those caps was tested and verified!

     A/ The Items
As you can spellcraft 100+ Damage Increase points on weapons themselves, no need to lost a mod for this on any other part of your stuff.

     B/ The Skills & the Stats
The skills involved into the Damage increase calculation are the Tactics, the Anatomy and Lumberjack. You have the calculation details in the UO Guide links. I'll just provide the values at 100, 120 and 130 skill points
       - Tactics: 67.5% at 100 skill points, 81.25% at 120 and 87.5% at 130 (130 tactics can be reach with the "Davy Jones Cloak" or the "Manteau de Krak" items).
       - Anatomy: 55% at 100 skill points, 65% at 120 and 70% at 130 (130 tactics can be reach with the "Davy Jones Cloak" or the "Manteau de Krak" items).
       - Lumberjack: 30% at 100 skill points, 34% at 120.
As you can see, for Damage increase purpose, Tactics > Anatomy > Lumberjack.

Strength is the only stat involved into the Damage Increase calculation. With 150 in strength the Damage Increase bonus is 50%

     C/ Conclusion
I recommend to avoid to spend points in Lumberjack as soon you are greater then Grand Master in Tactics & Anatomy.
Stuffed, to keep skill points and only reach the 200%, optimized solution is 150 strength + 130 Tactics + 115 Anatomy (105 base +10% from the cloak). The Maths: 50 + 87.5 + (115 / 2 + 5) = 200.


2/ Damage Calculation

     A/ Damage increase application
First thing doing by the system is your MIN and MAX damage calculation with the Damage Increase modifier applied.

For example, with a weapon with 20-25 base damage and 300% Damage increase (100% from items + 200% from Skills + Stats) your base damage will be MIN =  20 + 20 * 3 = 80 & MAX = 25 + 25 * 3 = 100.
Note about the floating point, numbers will be truncated at the end of this formula. Same weapon with 298,75% Damage increase: Min = 20 + 20 * 2.8575 = 79 (79.75 initially) MAX = 25 + 25 * 2.8575 = 99 (instead of 99,6875)

The interesting point is, initial base damage is added in the formula before applying the Damage increase (formula is BASE + BASE * DI). So, with 300% damage increase Maths are simple, your real base damage is BASE * 4.

     B/ Mitigation
Second point is the Mitigation. Mitigation is applied on top of your Base Damages. So against a mob with 70% physical resistance, your hit will be ( BASE * 4) * ( 1 - 0,70). In our example, MIN = 80 * 0.3 = 24 MAX = 100 * 0.3 = 30.
 
     C/ The whole calculation including Slayer abilities
The last point includes the Slayer test. If you are using a Slayer weapon, Slayer bonus will be applied after the mitigation.

     The complete Formula is: ( ( BASE + BASE * DI) * ( 1 - MITIGATION) ) * SLAYER BONUS


Safe travel warriors and take care of your gears!

umm...
but damage does increase and is noticeable up to 200% bonus on top of what your skills can add.
over 200 it still increased damage but is very minimal.

use a weapon with 100% damage increase than
use a weapon with 160% damage increase
you will notice the difference.

Hello Alk,

We did the test with Amair. A weapon with 94% DI and next with jewels to have 294%. Increase was just 1 more damage point because I wasn't at 100% on first try. Item DI is capped at 100%.
Did you add extra strength on your items? It can explain.

Damage keeps increasing over 200% but it is barley noticable and with it at 300% it was about 3-7 more damage per hit so after 200 it's not worth stacking more on.

I tested it with 120 skill 315 WDI and 150 strength much like you did.
The only differance is i dont have Lumberjacking
and I have noticed "almost" equal damage from a 30's skill new charactor using hign end gear.
it seems the WDI "Weapon Damage Increase" makes up for the lack of skill based damage when skills are low.
so the total max even tho i dont believe has a cap the numbers somewhere balance out between skill based damage and item based damage.

After it's all out to the public I'm sure some nerfs may be needed in the ammounts of damage increase we can obtain just to keep some gear sets a little bit better than the others.
 

*update*
 reading back on this i'll do more testing and find out where they balance out in hopes of preventing any extra script work.

Weapon Damage seems to have a built in cap and at 300% it dosent increase the phisical numbers anymore than 250% it seems but i'll let you find the exact number or i can help on Weapon damage because i'm almost done with the SDI testing.
Spell damage does not cap and at neerly 600SDI i was doing 100 damage more per ebolt. given our highest obtainable SDI will be close to 300% there wont be any need for a hard cap on SDI. also having inscription will increase your damage by about 10.
So having Inscription and or Eval will still benifit damage output no matter what your SDI is.

[yhaguen]

Agree SDI is not capped against mobs (PvE) but this is another topic. I let you open it

About Weapon Damage increase, all the tests I did work as I described. Global cap is 300% with linear damage increment till the cap, and only 100% is allowed to item bonuses. I do exactly the same damages with 100% WDI on stuff and with 300% WDI. Exactly the same, not even 1 damage more.

I think we have to meet, share our stuff and do the test together.

Cheers,
Yhaguen.

[alk760]

no i believe you it seems your numbers are spot on and a bonus of 300% is all she wrote.

how you reach that 300% tho is user prefferance.

[Lucian Kaine]

Is 300% obtainable for WDI? or is it like SDI....yes its obtainable, but nearly impossible. Has anyone been able to get anything over 220% SDI without the help of Amairgen? 

[yhaguen]

300% WDI is not hard. 100% can be crafted directly on the weapon. Then you need 150 strength plus 2 power scrolls, Anat + Tactics and/or the Davy Jones cloak. A new player can reach it quite fast.
