Pokémon GO – Use Razz Berries and better Pokéballs to capture Pokémon

If you’ve found a rare Pokémon (or one with an incredibly-high CP) in the wild, your standard-issue Pokéballs may not work to contain them — or worse, send them running. Instead, once you hit level 6, you can use Razz Berries (and later on, Great and Ultra Balls) to improve your chances of containing wild creatures.

Razz Berries, after being administered, lull the Pokémon somewhat — even if you miss a throw, you’ll have an increased chance of catching the Pokémon until you hit them. If you do catch them with an off-throw and they escape, however, you’ll need to feed them another Razz Berry.
