Lucky Eggs
Lucky Eggs are consumable items that allow you to earn double XP for 30 minutes. You can be really clever about it and combine the use of a Lucky Egg with Incense, meaning that you’ll have a ton of Pokemon nearby waiting to be caught and a huge amount of XP tied to each one. Of course, that’s just the start of how to use your Lucky Eggs with other means of earning XP to really rake it in.
One of the best ways to send your XP sky-rocketing is to keep all of your Candy together for all Pokemon and don’t evolve them until you’re ready to use your Lucky Egg. At this point, activate the Lucky Egg and begin the Evolution process. Thanks to the multiplier effect, you’ll get 1000 XP for each Pokemon you evolve. Throw in a couple of PokeStop visits and some stops at your local Gym and you’ll find yourself a couple levels up by the end of the 30-minute period.
