If you’ve been playing Pokemon Go for a while, you should be aware of the fact that Dratini is one of the most difficult and rarest Pokemon to come by in the game. Also, it’s even harder to find enough of them in the hopes of evolving one into a Dragonite.
However, one Pokemon Go player might have cracked an important piece of the puzzle to acquire a lot of Dratinis in quick succession. This player noticed a peculiar trend as he encountered several Dratinis over a short period of time while visiting a Magikarp nest near his home. He explains the entire ordeal via a Reddit post which you can read below:
With the update a few weeks ago, new Pokemon spawn locations were added along a paved walking trail (marked on Google maps) next to my home. This trail runs alongside a creek, and I noted that there were 2 distinct spawn points consistently showing Magikarps…one spawned at about :15 after the hour, and the other :40 after the hour.
The player also observes how the Dratini showed up at specific times during the day near the nest:
While farming Magikarps, I started to note the occasional Dratini at these same locations…they were showing up once a day. For the past 3 days, I have been able to farm the Dratini…the first day they showed up at 20:15 and 20:40; yesterday they showed up at 16:15 and 16:40. Although the Dratini show up on my nearby list…I have to jog about 1/2 mile to reach them because a cliff that runs alongside the creek behind my house restricts direct access. Today, I decided to get a headstart, theorizing that maybe they were spawning every 20 hours. I walked down there at 12:00…and sure enough the Dratini spawned at 12:15 on one location and 12:40 at the other.
Well, there you go, all you need to do in order to have a steady supply of Dratinis is find a Magikarp spawn nest, and then you must visit it every day in order for a Dratini to appear every 20 hours or so.
