After reading through an old Reddit post about this, I will explain my view on the best method of IV stone farming. There are three ways to obtain IV stones in the game at this current point:
- Pokepon
- Rock Smashing
- Pickup Ability
In this post I will try to explain every method and calculate the chances of getting IV stones from each method:
#Pokepon
The chance of obtaining an IV stone as stated on the Wiki:
± 8,16% (before obtaining Girafarigite)
± 8,32% (after obtaining Girafarigite)
You can use Pokepon every 20 minutes and walk around for a maximum of 1,500 steps.
#Rock Smash method
While you use the Rock Smash method you can press P to refresh the map (and respawn) the rock after each Rock Smash, walk up and down one step from the rock and keep going.
As states on the Wiki, which is in the eyes of the developers not 100% accurate, the chances at Rock Smashing are as follows:
(We will use those percentages for the calculation anyway)
- 25% Pokemon encounter
- 25% Item drop
- 50% Nothing at all
The chance of getting an IV stone from an Item Drop = ± 3,57% ( 1/28 ) as stated in comments in the post on Reddit.
With this information you will have a 0,25 x 0,0357 = 0,8925% ( ± 1/112 ) chance of getting an IV stone from a random rock.
#Pickup Ability
The third method of obtaining IV stones is by Leveling up a party full of Pokemon with the Pickup Ability over Lv. 71. The Pickup Ability will activate after each battle with a 10% chance of obtaining an item. The Pickup Table from Insurgence got a 1% chance of obtaining an IV stone from Pickup.
So, we should do the calculation: 6 Pokemon x 0,10 x 0,01 = 0,6% ( ± 1/167 ) change after every battle.
#Combinations
At this point people will start to mention:
“Why don’t you use all methods at the same time?”
The old post on Reddit stated to use the Rock Smashing method and the Pickup method at the same time, but I will tell you why this is not the best method:
The Reddit post did not consider TIME to affect the combination of methods
Combining the methods:
#Rock Smash + Pickup
This is the point where the calculations deviate from each other. Many people stated to use both methods, so they have a chance to get an IV stone Item drop from Rock Smashing and have a chance of picking up IV stones from the Pickup Ability.
- 25% Pokemon encounter >> 0,6% ( ± 1/167 )
- 25% Item drop >> 3,57% ( ± 1/28 )
- 50% Nothing at all >> 0%
Adding those together: (0,6% x 0,25) + (3,57% x 0,25) = 1,0425% ( ± 1/96 ) chance of getting an IV stone from a random rock.
This means you have an ADDED 0,15% chance of getting an IV stone from a random rock if you add the Pickup method to the Rock Smashing method. Now you wonder why this is absolutely NOT worth it. Let me explain this:
- Only using Rock Smash and run away from Pokemon:
- You can use a low level rock smasher, you can always run away from the encounters (+ a shiny would be easier to catch).
- You do not have to pay much attention while doing the grind of the Rock Smash method.
- You can start this method from the start of your game, as there are no requirement, except for having a Fighting-type move. - Rock Smash + Pickup
- You need 6x a Pokemon with the Pickup Ability above Lv. 71. (You need time to train those Pokemon and at least one of them needs to have a Fighting-type move (Like Diggersby)).
- You HAVE to check your Pickup Pokemon after every encounter to not decrease the chance of getting an item (as a Pokemon holding an item cannot obtain one), and take the items from the Pokemon.
- You need to faint all the encounters: Using a Move takes time AND your encounters will be around Lv. 71 with the possiblity of having the Sturdy Ability (You need a multi-hit move or use two moves to kill them).
The time you use to faint all the encounters AND check your Pokemon after every encounter is NOT worth the 0,15% added chance of obtaining an IV stone. In the time you spend doing those things, you can smash over twice as much rocks without doing all the handlings with the Pickup Pokemon.
#Addition
All methods are still usefull in their own way. I would recommend using the methods in different kind of situations:
- Pokepon: While progression through the story or
doing other stuff like breeding. - Rock Smash: Grind for IV stones.
- Pickup Ability: While doing leveling (at the Level trainer) or EV training in Friend Safari or at the EV trainer.
