Pokédex Rank

The Pokédex is done very differently in Pokémon Legends: Arceus. Instead of the Pokédex being complete when you catch a Pokémon, you now have various research tasks to complete, with each Pokémon having specific tasks suited to their species such as using a move, evolution, catching them or defeating them with specific moves. Full Details for each Pokémon can be found in our Pokédex

With this, each Pokémon has a Research Level that goes up to 10 for when you achieve 10 of them, though some tasks with the red mark offer more of a boost. When you reach Rank 10, the Pokédex is deemed complete and you will get an increased Shiny Chance for that Pokémon. If you then complete all tasks, the Pokédex entry is perfect and you get an even bigger boost to the Shiny chance for it.

The Pokédex completion however is locked to the game's progression. When you speak to Laventon at any of the Base Camps, he will evaluate your current progress. For each Research entry you complete, you'll get 10 Points, with tasks that are red giving you more of a boost of 20 Points for it. A Completed entry will give you 100 Points.

When you hit certain point thresholds, you will then rank up when you next talk to Cyllene in Jubilife Village. This will give you a variety of boosts, new recipes and act like badges in the prior games; unlock the level of Pokémon you can use. You will also need to hit a certain rank before you can go to the next area as the story progresses
