In this guide, you will come to know how to level up your Pokemon Stats in Pokemon Legends Arceus. You have to follow the step-by-step instructions in this guide to do so.
There were EVs for effort values in previous Pokemon games and IVs for individual values. These systems are used to determine pokemon stats and the significant variation in stats among untrained pokemon of the same species.

You will need to make sure you have strong pokemon by having max Ivs or Evs. In Pokemon Legends Arceus, they’ve changed the working process, and instead, they’ve given a thing called effort levels. When you capture pokemon and check their stats on the summary screen, they have a number with a bit of progression bar next to it for each of the different stat types.

This number will change every time you capture a different kind of pokemon and will usually range between 0 and 3; these numbers are the effort levels of your pokemon. They’re independent of each of the different stat types; the higher this effort level gets for each of the stats on your pokemon, the more powerful it will become for that particular stat.
If you want to make your pokemon more powerful or the most powerful, then you have to reach effort level 10 for each of these stats or at least the stats that matter for that particular pokemon.

Some pokemon are special attack focused while others are physically attacked focused, and if you max out the opposite stat of the specific pokemon, it will not help you. Like a Gengar, who has a significantly higher special attack and lower physical attack, do not use physical attack moves.

This pokemon does not use its physical attacks most of the time, so you have to upgrade its special attacks. Few pokemon you catch in the game have higher starting effort levels because IVs are the part of the game behind the scenes, and also it affects the effort level of the pokemon once you catch it, as shown in the image below.

Some have effort level three in different stats when you catch the Pokemon, while others may have one or zero. There are multiple items in the game that you can find, and they can raise the effort levels of your Pokemon. You can use the grit to increase the effort level of Pokemon, which boosts the effort level for one of the pokemon stats, and four grit items have different capped thresholds, which will help to raise the effort level, as shown in the image below.

To raise your Pokemon’s effort levels to level 3, you will need to use grit dust on each stat to bring it up to level 3. Once you’ve reached level 3, grit dust will no longer be compatible with that Pokemon. That’s when you move up to the next tier of grit item called the grit gravel, which is similar to the grit dust; however, it will take your Pokemon’s effort levels from three up to level six. Move on to the grit pebble, which is similar to before, except it will take your Pokemon’s effort level threshold from six up to nine.
The grit rock, which is used to raise the Pokemon’s effort level from nine to ten, which will be the maximum effort level in your pokemon stats, will give you a bonus to that particular stat. This bonus increases at each threshold of the different grit items. Hence, you get a more significant jump in stats from levels 3 to 4 from levels 6 to 7 and 9 to 10. If you want to get your Pokemon to be even stronger than it currently is, you need to focus on the grit dust, gravel pebbles, and rocks to raise their effort levels.
