The loot percentages - Allakhazam

[Gangrenous]

So Ememjr and I have been bantering away in Discord about loot percentages. I have always hated Allakhazam percentages, even back when I relied on it in the eq1 days. Just taking a random mobs loot...

So looking at this I can already discern the loot tables. There are definitely some global ones. One is by the mobs model type, which I added a global type this week on my server just for that. Then the other is the mobs level range, I think one more is just for that zone. So we definitely have global loot. What bothers me are the percentages. These obviously did not come from hard statistics provided by real player numbers. Ememjr says they got a dump of data from SOE at one time, probably did. But the numbers still do not add up. If you threw the 5 ghost items from the model_type into a loot table at 21% for each item, that is 105% of getting an item. Of course the first item always gets a higher chance, even if you randomize the list of items on each roll.

I am just trying to get a better grasp on how to do loot. Ultimately I am scaling my percentages down in the end with a server rule.

Open for much discussion on this.

i believe that alla loot tables do show mostly accurate drop percentages, but what it does not shows what table they belonged in but once you look at enough of them it gets easier to figure out a table lets take lev 1-9 adept spells for instance the percentage is .0132 % chance to get a spell and there are 152 apedt in that range if you multiply that out it is 2% chance total to get an adept spell so i have created an adept T0 loot table with 152 spell scrolls in it with a 2% chance of winning, with my loot determination you will have an equal chance at 1 of those 152 spells

another example is T0 levle 1-9 vendor trash, if you add up all the vendor trash that have either 1%(2) .1538%(1) or .0769 %(11) they all add up to 3% so i created a table for that with a 3% chance of winning again if the table is won the the items in the table my formula will give an proper chance of which item is won based on its probabilty but there is a guaranteed win since the loot table won

I no longer random up to 132 times when the loot table has 132 items in it

You guys know about the Daybreak Census? I believe those collections had loot tables defined (at least I thought they did when they were data.soe.com)


Collection List: http://census.daybreakgames.com/get/eq2/



Maybe they were called "Treasureclass": http://census.daybreakgames.com/get/eq2/treasureclass

Code: Select all
