Encounter Rates

Overview

An encounter rate refers to how likely you are to encounter a particular rarity of Pokemon. For example, the base Very Rare encounter rate is 1/600; this means, for each wild Pokemon encounter, there is a 1/600 chance for a Pokemon to be Very Rare. If there are multiple Very Rare Pokemon in that area, the rate is still 1/600, and the Very Rare Pokemon is chosen at random.

Note that the encounter rate for non-event legendaries is dependent on your LLE. The exact formula is not known, but the average LLE when encountering a legend is around 1/95k without GM and 1/63k with GM under base rates.

Legendless Encounters (LLE)

LLE is a mechanism in which your chance of encountering legendary Pokemon increases the longer you go without encountering one. Each time you encounter a non-legendary wild Pokemon, in a location where a legendary can be encountered, your LLE for that legendary increases by 1. As your LLE increases, so does your legendary encounter rate.

LLE is per legendary. If you encounter 100 wild Pokemon in Mewtwo's Lair without finding Mewtwo, your "Mewtwo LLE" will increase by 100.

The boost rate follows an s-curve. This means that the boost starts off slowly, and increases slowly, then around the average encounter rate (95-100K) growth accelerates exponentially, reaching max boost very quickly, then it tapers off around 200K LLE at its maximum boost value of ~80% (This does not mean an 80% chance of encounter, but that the chance of an encounter is boosted by 80%).

Sync rate also increases with LLE. From 0 LLE, you will have a 26% sync rate. At 150k LLE, the sync rate caps out at 100%.

Mining uses LLE. 1 LLE is granted for every successful mining action if you meet the requirements to encounter the mining legendaries.

Event legendaries are unaffected by LLE.

You can view your current LLE with the /lle command.

LLE used to be shared across all legendaries. If you have still have LLE from this old system, you can assign it to a legendary of your choice with the /setlle command.

Notes
