Story to Increase Survey Corps Rank – Pokémon Legends: Arceus
To rank up in the survey corps, you must accomplish research tasks.
The more research points you get, the faster you'll be able to increase your army.
If you want to rank up in the Survey Corps, you need to earn research points. Research points are awarded for doing extra tasks on your surveys.
As a researcher, you'll have to travel to new areas regularly to study Pokemon.
As you do more research on various Pokemon, you'll advance the Galaxy Expedition Team's cause.
In the world of Pokemon, you can keep track of your research points by using a Pokedex.
The bottom right corner of your Pokedex shows you how many Research points you have, but more importantly, how many more points you need to rank up.
Get Rewards for increasing Rank
Ranking up is important because it grants you access to new areas in the Hisul region.
These new areas are home to other creatures that you can study.
In order to fill the Pokedex, you must do research on various Pokemon and areas. The more of these you do, the faster it is for you to complete the Pokedex.
Additionally, each increase in rank unlocks different features and rewards.
