How does chance of defense work

PenNPaper

 Greetings. I how does chance of defense work I read an article online but still leaves questions. I am playing a archer which has no defense skills so am wondering if chance of defense would work for him. The web site was mention defense but does this include chance of defense and armor rating?

Hi Pen.Short answer: Skill in your Weapon in hand/equiped is your defense.

Longer version specfic to you
 1) Ultima Online compares your Archery Skill to the Weapin or Wrestling Skill of you target
- if your Archery Skil equals your target's Skill you have a 50% chsnce to hit
-  the reverse is also true, your foe will have a 50% chance to hit you with their atacks
- if the Attacker has greater Skill, the chance to hit rises*
- if the Defendet is more Skilled chance to hit lowers*

* formula is (Attacker Skill +20) 
   divided by [(Defender Skill +20) multiplied by 2]
This equals your % chance to hit so (100 skill) divide by (100 skill)x2 equals 0.5, or 50%

2) If you do not Hit, you Miss. But a Miss can also be called a Defense (different from Parry)

3) Defense Chance Increase ( and also Hit Chance Increase) are multipliers** for the Attacker and Defender formula shown above. Increase of 10% means a 1.1 multiplier. 30% would be 1.3
** [ (Attacker Skill +20)(Hit Chance Increase)]
      divided by [(Defender Skill +20)(Defense Chance Increase)] multiplied by 2
- So if you have Defense Chance Increase 20% your opponent will be reduced from a 50% chance to hit to 41.6%  even if you are both at equal Skill.

Browsing the wiki I could not find the formula referenced, but would be grateful if some else can.

Ho how would that relate to an archer without parry with like 100 dex and say 20 or more chance of defense. So looking to raise that anywhere between 30% to 50%?

Glad you found the answers. Just so others reading this thread know, Parry and Dexterity have nothing to do with Hit/Defense chance.

Most of the stats are covered here https://uo.com/wiki/ultima-online-wiki/skills/melee-fighting/
