Popular UO Mechanics

UO game mechanics are a very interesting field of research. They can be as complex as quantum mechanics. I tell you anyone who thinks they know the uo game mechanics rules does not fully understand them. 

I’m on a quest to define these rules, lay down some foundations of which the game is based on. So we can more easily understand what is working as intended and what is not. Only God knows the answer to the true game mechanics, and in this world that is Bleak. And luckily enough for us, he is still working for uo, watching over us.

Ill be posing a series of discussions on game mechanics to try and define and make sense of the rules. I used to enjoy editing the uoguide, however now I’m moving onto the holy grail of guides, the official uo wiki. Here is our issue, there have been unwritten game mechanics since day 1. For example, the delay between casting and hitting last target on most magery spells has always been there, but never written, then there have been publishes to change the unwritten rules (100 of date). Most of the information is out there somewhere, just not all in the right place. The ultimate dream would be for the information to be available in game. However I can understand that a thesis on magic arrow may be too much for a new player to take on. So for now I shall be happy to get the info on uo wiki. I was amazed when I read the necromancy page and saw formulas I never saw before, the blueprints to uo. I would like to duplicate this for all aspects of uo and game mechanics. People often say you learn something new everyday about uo, and for a 16 year vet, you may think this would no longer hold true. However true it does remain.

We’re going to first talk about damage in uo, I think many people will be surprised to know just how many types of damage there are.

(physical, fire, cold, poison, energy and chaos which is any of these at random) are just sub categories of kinetic damage (includes melee and ranged),  and spell damage,

but there is also Direct damage. 

So now we have separated the damages, we can now talk about the effects of one another. 

Now each of these damages has different damage caps and further complicating things, pvm caps differ to pvp caps. And these caps are then further decided into item total caps and hard caps. Damage needs to be defined so we understand what we’re being hit with and why it hurts so much. 

Generally we (the elite old guard) have a good understanding of damages and caps. But there are 1 or 2 odd things that happen that we treat as exceptions.

Let us talk about reflect physical damage. This property helps us identify and seperate damages in game. It’s al type of filter.

Some people say, why doesn’t rpd reflect this or that? And it’s not because it’s not working or “just because it doesn’t” it’s all to do with the damage type. Many pvpers will quickly realise how little things are reflected by rpd and scratch their head in confusion. So first let’s get one thing out of the way. Armour ignore, this hit does do physical damage, however the clue is in the title. 

Most of the other time a warrior hits you with a physical weapon and it’s not reflected, it’s because it’s dealing “direct damage” as part of a special attack. (A small portion of the initial hit will be physical damage). 

What about bleed, earthquake, bombard and chaos damage spells? well it appears that no non physical kinetic damage is reflected. So we shoul really call RPD, RPKD (reflect physical kinetic damage)

We have another tool to help us devise what damage is, attunement. Attunement works similar to rpd. Except it will catch AI, as it’s not armour. And it will catch all kinetic damage.

Will not catch bleed and chaos spells or earthquake, all good, all obeying the laws of Bleak. But wait, it catches bombard. But we know bombard is physical, we know bombard is not kinetic as it’s not reflected by rpkd. So what is it? This is an anomaly I am stuck on. An exception to a rule. Perhaps it’s a bug? Not one i’d wish to report.

We have to also accept in uo that to every rule there will be exceptions. Some bizarre ones at that. But many times the exceptions are there for reasons we do not understand. But when I can identify an unnecessary exception, I shall try to remove it by reporting it as a bug to simplify the rules.

You see when writing a simple spell description, you do not realise how much research needs to be done to simply describe a spell/buff/property. Everything needs to be put into a context or category. You cannot simply say that x gives +25% damage increase. This is meaningless, what damage? And does it go above the cap, and what cap?

I am sure in the upcoming weeks the bug section will become a little larger as we delve deep into the minutia of uo game mechanics. 
I tell you the truth, tis better to do 10 damage on the right target than 100 damage on the wrong target.

    I would very much like to see how the entire things works. A collaboration of talented software engineers and technical writers to put absolutely everything on paper in absolute terms....that or they can let me see the source code.

     Are you sure they are going to let you edit the official uo.wiki?

    omg. :D

    Good luck everyone involved!

    And grats if you pull off some of this as well.

    Don’t worry I can’t edit it myself. Would you trust me with power?

    I think I'd trust @Mervyn to update the UO wiki, I don't always agree with his suggestions, but he seems to be knowledgeable as to how game mechanics work in UO.

    There's a lot of hidden information on many things so it involves extensive testing to figure out most of it, especially the undocumented mechanics.

    Many things have been changed without the information being updated to reflect the changes.
    as well.
    Remove or change casting focus & poison immunity it reduces the need for "Player Skill" it's garbage. rant2 Bring timing back and eliminate chance in pvp!

    Today, we will be talking about the best strategy to counteract magic reflect. Magic Reflect as we all know can have a pool of up to 100 if the caster is an inscribe mage, (60 with just 120 eval/magery) but what does this mean? If you're hit with a pool of damage, the spell will be reflected if the magic reflect pool is equal or greater to the spell pool, here are the current (undocumented) pools from what i can tell:

    blood oath 40
    corpse skin 30
    evil omen necro/spirit speak skill dependant 50-70
    mind rot 40
    pain spike 20
    poison strike 50
    strangle 60
    wither N/A

    word of death 100

    all magery spells = circle x 10, EG first level spells have a pool of 10.
    meteor/chain lightning/EQ/mass curse NA
    hit spell NA

    netherbolt 10
    purge magic: mysticism/focus/imbue skill dependant 20-60 (plus a chance to purge the spell anyway)
    sleep 30
    mass sleep NA
    bombard 60
    spell plague 70
    hail storm na
    nether cyclone NA

    Where there is no pool (N/A), the spell cannot be reflected at all and the magic reflect pool remains in tact.

    Incidently, the amount of spell pool that each spell drains (from what i can tell) does not factor in at all the caster's skills for most of the spells, with the exception of purge magic and evil omen. This is crucial for determing which spell to cast to smash someone's magic reflect while minimising damage to yourself. Ofcourse there is another factor to bear in mind with magic reflect, that only weaken, clumsy, and feeblemind will disrupt someone's casting who is protected by magic reflect.

    Some people prefer to spam weaken/feeblemind/clumsy however bear in mind it will take 10 of these to completely remove the pool, ofcourse you don't need to remove the whole pool, only enough for your next spell to break the pool.

    I personally pefer evil omen, with it's rapid casting time and a massive pool breaking power. But when I can't cast that, I would use Curse, mainly because there's no backfire and if you do happen to break the pool, it would also serve as a decent debuff to your opponent (rather than hitting your oponent with paralyze or mana vampire, which would serve only to waste your mana)




    I tell you the truth, tis better to do 10 damage on the right target than 100 damage on the wrong target.

    • I'd trust you as far as I can throw you. :)  But to be fair, this is one of your interests, I think you'd give it a good effort, you go into far more detail than me. Nice first post.
    • And Mariah... I think he has a crush on you. <3

    Mervyn, I fully support your efforts and anything else that would keep you too busy to file "bug" reports :smile:
    Jokes aside, nice post.
