Hi,
I’m personally one of the farmer (monsters) who did the jungle dungeon the most, from all these runs I’ve definitely saw a difference with luck rings, I always farm with luck rings now but one ring is 25 luck so 2 rings is 50 luck + you got the 50 base luck for a total of 100 luck if you’re 20 with 2 rings.
I’ve seem from average of 33.333 % more drop in reagents with both rings. I’m basing on reagents cause it’s a “rare” drop and I always keep track of my reagents.
Now for the luck potions, from the super friends wiki (I don’t know if this is 100% true data) it says that the luck pots give 50 points of luck and that would be 5% more. I don’t know if they’re talking about 5% more drops in overall from what they seen or 5% of your currant luck, I always interpreted it as : 5% of your current luck (again I might be wrong.
But if it’s the case then it would mean that : 1 pots +2 ring +20 lvl = 105 luck, so with the 2 rings it can be a little boost from what I understand but with only 50 base luck you’d get 52.50 (probably down to 52). so in raid people use their good rings so the difference from what I understand is really small but if you were to use rings of luck in raid it might help.
Else if we calculate it with the 50 points of luck, with no luck rings (like in raid) you’d get the same amount of luck as with 2 rings on, in this case I think from what I’ve seen it would mean a 33.33% more drops in average.
I say 33.33% because over a lots and a lots of dungeon runs I’ve figured that by the time I fill my inventory and have to go to seller I get an average of 30 reagents (with 2 rings of luck) and without them it’s 20 reagents, it might take me half a dungeon more when I don’t use the 2 rings so it might not be exactly 33.33 but I’d say that it seems pretty close to that.
I’ve farmed over 75k monsters in the jungle dungeons, so I had time to establish averages.
I hope it’ll help you a bit in your quest on finding how luck work but It would be awesome to have 100% sure data from devs or confirmation on those data from superfriends.
