Hi. I did a quick search for any topic on this and could't find what I was looking for, so here goes.
How does magic find work?
The way i currently understand it:
Say i kill Azmodan with 0% mf and no NV.
The game creates a table of loot that he drops, like: 1 t13 bow, 1 t10 armor, 1 t09 legs etc.
Each of those have a % chance of beeing white, blue, yellow, legendary.
In the loot table is a helion crossbow. On azmodan it has a 50% chance of being white, 30 for blue etc.
Should i have any magic find, it would increase the chance for blue, yellow, legend?
Or am i way off?
2nd: think of magic find improving the quality of items dropped. if you've got 100% mf on your gear and there is a 1% chance this boss drops a blue it will drop a blue with a 2% chance.
I am well aware that magic find improves the chance of getting better quality items. What i wonder is how it is determined what items drop. Like is it a predefined loot table that has the quality of the predefined item types increased? Or is every item defined on 2 percent for blue and then random item type @ each drop? Or maybe something different..
Actually its similar to D2 in the sense a boss (or mob) will have a loot table to pull from. Lets say it pulls ilvl61 gloves. Since it is a boss, the base quality is 'magic' (or with 5 NV, the first 2 are guaranteed to be rare base). There is then a % that this item can be rare, so lets just call it 1% for the sake of math. This item will pick a random number 1-100, if it is a 1, boom you have a rare. With Magic find, that % is directly affected so, as previously stated, 100% mf on a 1% chance is now 2%. And of course, I'm certain the servers aren't "rolling" 1-100, but its a simplified way to express what is going on. This continues on for legendaries as well. magic > rare > legendary/set is the progress of upgrade. So if there is a 1% chance for the item to be rare and a 1% chance for it to then become legendary, then the base chance that the magic item will be legendary is 1% * 1% or 0.01%. Conversely with 100% mf, the chance would be 2% * 2% or .04%. So then you see magic find affects getting set and legendary items more than rares.. however that is on a purely % basis. A difference of .03% will matter almost nothing to you, a small fraction of the 'pool', but is significant on the scale of every single player. These are also random numbers I chose and not actual values.. and also on the assumption that an item can be a legendary/set. Otherwise it stops at rare.
