The descriptions in game especially in the wiki are very confusing. As follows,for the legendary weapon "Infinity":
Infinity is obtained randomly from any suitable loot source but has an
increased chance to drop from Doc Mercy located in Three Horns –
Valley.
What is this "increased" chance to drop? 1%? 10%? And what's the base chance to start out?
Doing some research as I was wondering this myself. . .
This forum post at Gamefaqs suggests that:
I am doing further research.
It has a very minor effect on legendary drop rates, that you're probably better off using another relic. It only affects white (common) and non-white drop rates (and not legendary drop rates, specifically).
From this somethingawful.com forum post by user, gibbed:
So I just investigated the Vault Hunter Relic data.
It modifies two attributes:
GD_Balance.Weighting.GearDrops_RareWeightModifier: +0.05 GD_Balance.Weighting.GearDrops_CommonWeightModifier: -0.06
Let's set them to +100.00 and -100.00!
Net result: I have not seen a single white weapon drop, greens drop, seen a few blues. Nothing else.
So, what I can gauge from this, is that it shifts a 5% of your chance for whites into non-whites. Doesn't touch anything else. Very low impact, perhaps bordering on useless.
Some of differences in True Vault Hunter Mode as opposed to Normal mode are:
...
- Better Loot: Due to the nature of difficulty increase and the fact the game becomes more difficult, in True Vault Hunter Mode there is a higher chance of enemies dropping better loot and chest also will contain better loot.
- Better Loot more frequently: Enemies in True Vault Hunter Mode will be have a higher percentage chance of dropping better loot as they have more health and are more difficult to defeat.

Low. Really really really low. Legendary weapons drop with single digit percent chances at best, and that's from the proper boss (though some bosses seem to usually drop a legendary the first time when fought only).
There's no single percentage though, different items have different methods of obtaining:
Lots of people seem convinced the Infinity has a lower drop rate but I haven't found anywhere that lists drop chances formally (either from the game's code or crowdsourced experiments), and the Cobra's drop rate and method was released publicly by a gearbox employee (because no one had found it...)
There's a rumor going around that the legendary drop rate from a boss is 1/20 but from my own observations this seems optimistically high. Certain high-drop rate bosses like the Warrior seem to drop one about this often, but at best they'll drop one of their legendaries at this rate rather than having a 1/20 chance for each. Which means you'll probably have to fight Warrior >100 times to get one of each legendary he has, if you're lucky.
