Incense is one of two items that attract Pokémon when used. After applying Incense, a 30 minute period begins where wild Pokémon will be attracted to the current location of the Trainer who used the item. This effect is isolated to just the user of the item, unlike the Lure Module that affects all trainers nearby.
While an Incense is active you will encounter a spawned Pokémon every 5 minutes (if not moving), if you are moving at least 200m away from the previous spawn the Incense effect is decreased to spawn a Pokémon every minute. This means it’s possible to catch 30 Pokémon if you are quickly moving between captures.
These can also be purchased in 1, 8, 25 increments from the Shop.
