This is from the sticky about game information...if anyone would take the time to read them thy may learn a thing or two...
Luck:
You kill a monster. Items drop out of said monster. Between those two actions, a chance roll occurs. The item that drops, let's say it's a sword, has a chance of being either Normal, Enhanced, Rare, Legendary, or Unique. Now for a better way to represent this:
***PLEASE NOTE***
THE NUMBERS USED HERE DO NOT REPRESENT ACTUAL CHANCE RATES.
THEY ARE ONLY BEING USED TO ILLUSTRATE HOW LUCK WORKS.
180 - Normal
14 - Enhanced
3 - Rare
2 - Legendary
1 - Unique
180+14+3+2+1 = 200
Let's say these are the numbers for when you are wearing no Luck items. They do not represent the game's drop rates and are only used for this explanation. This would mean that the sword which is about to drop has a 90% chance of being Normal, 7% Enhanced, 1.5% Rare, 1% Legendary, and 0.5% Unique.
Now, let's say you're wearing Luck gear totaling 80 Luck. This subtracts 80 from the Normal number which is now 100 in the case of my example numbers. Suddenly:
100 - Normal
14 - Enhanced
3 - Rare
2 - Legendary
1 - Unique
100+14+3+2+1 = 120
This means that now there's only an 83.33% chance of a Normal roll while all of the higher rarities increase in their percentage chance: 11.67% Enhanced, 2.5% Rare, 1.67% Legendary, and 0.833% Unique. Sounds pretty good, right? Hold tight, here's where it gets interesting.
Monsters which are Rare, Legendary, or Bosses are already set to drop selections from different rarity groups. To explain, let's say you're about to land the killing blow to Shulgoth. This time there's a series of chance rolls. This is because monsters who have a rarity level higher than Normal have multiple chance rolls when it comes to dropping loot. For example:
Chance Roll #1:
Normal -> Unique
2 items from this group
Chance Roll #2:
Enhanced -> Unique
1 item from this group
Chance Roll #3:
Rare - > Unique
1 item from this group
There are a lot of percentage chances at play in these rolls, naturally. However, Luck only affects Chance Roll #1. Why? Because it's the only one that has Normal items as a possibility.
SO! Luck improves the quality of your drops by reducing the percentage chance that a drop is Normal quality. It does not directly improve the percentage chance that a drop is higher quality but instead indirectly. It also does not increase the number of drops in any way. Nor does it improve chance rolls where Normal items are not a possible drop.

As you all know, the vast majority of equipment is faction-specific, barring quest items. Many have commented on how they feel that they've been getting drops for other factions more than that of their character's faction. However, ever since the game launched, the drop rate has been 60/20/20. This means there's a 60% chance a drop will be for your character's faction while there's a 20% it'll be for one of the other two factions.
The only changes in this ratio occurred prior to the game's Halloween launch. During Community Day in May, it was 33/33/33. During alpha/beta, it was 50/25/25.

You simply use one of the augmenting machines method, nano-forge etc, that is used to get rid of unwanted quest items by dropping them to the ground. Do this with a sword/armor you already have (i use wart's leg) and it will drop, then pick it up again and the mini-game will trigger.
For those of you unfamiliar with this method simply fill your inventory with items and put the sword/armor into the augmenting machine. With the machine still open rearrange your inventory so the item won't fit back in, then hit cancel on the machine and the item will drop with a warning saying this.
As for mods I don't believe it's possible since they take up only one slot. Hope this helps those waiting for those pesky sword drops.
