Spawn Calculator

The Spawn Calculator estimates the chance of a chosen Pokemon spawning under specific biome, location, time, weather, height, light, moon, and structure conditions. It supports both the standard wild spawner and the separate Legendary spawner.

How it works

Standard spawn results compare matching rarity weights at one location. Legendary results use the separate Legendary pool and its flat-distinct selection, together with the configured attempt interval and success chance. The same calculator is linked from each species page under Spawns.

The Consecutive times setting evaluates a block of consecutive times of day and weights each time by its real in-game length, so longer times (such as Night) count more than short ones (such as Midnight). With Strict block enabled, Find best chance only accepts blocks where the species spawns during every time in the block.

Limitations

Mega Boss spawning is not included. Party-lead requirements, calendar requirements, non-biome anticonditions, and the exact distribution of viable locations around a player are not modelled. Legendary wait times therefore assume that a viable location exists when an attempt succeeds.
