Purifying gives the Pokémon a significant increase in Combat Power and it will cost less candies to evolve. Make sure you Purify a Pokémon BEFORE you evolve it so you can use less candies. Just FYI, if you already evolved a Shadow Pokemon, you can still purify it.
Purifying a Shadow Pokémon will improve their appraisal and reduce the amount of Stardust and Candy required for them to Power Up, Evolve, or learn a new attack. When Purified, a Shadow Pokémon will forget Frustration and learn Return, a Charged Attack that's exclusive to Purified Pokémon.
If you decide to purify a Shadow Pokémon, the benefits are actually quite nice. But, it's important to remember that, ultimately, you are losing the best Shadow feature, the 20% attack bonus. Purified Pokémon are cheaper to power up in terms of Stardust and Candy.
Yes keep your shadow Pokemon unpurified. Shadow Pokemon works as angry Pokemon and will deal damage more faster then Normal or Purified Pokemon. The attack power of a Shadow Pokemon is boosted by 1.2x or 20%, making its fast attack hit significantly harder. So it's better to keep them unpurified.
The only benefit in evolving before purifying is adding to the "Purified" counter of the evolved form in your dex. Don't evolve it till December community day just in case the move comes back. Charizard is bad without the move.
When you purify a Pokemon, it becomes cheaper to power up, both with candy and stardust. There's also a reduced cost when it comes to evolving a purified Pokemon as well. This stacks with the Lucky effect, so a Lucky Purified Pokemon gets both the reduced candy costs AND a massively discounted stardust cost.
If you're goal is to get a high CP shiny of the pokemon and the shiny you have is high level and If you know you wont be putting much candy into it, go for it. I'd say go for it if you want the shiny and its a pokemon you'd like to use/have, as I believe personal like of a pokemon >>> than any iv's.
Azelf, Mesprit, and Uxie are the rarest Pokemon in Pokemon Go because they're region exclusive. The three Legendary Pokemon spawn in the wild but only in the following regions: Azelf – North America, South America, and Greenland. Mesprit – Europe, Africa, Middle East, and India.
Is it better to purify or keep shadow? If you're attempting to complete research, attain a goal, or some other third oddity in the game, by all means, Purify all your Pokemon. But if you're seeking the most rare Pokemon in Pokemon GO, or you like Pokemon that WIN in Raids, keep your Shadows!
Purifying a Shadow Pokémon will also make it stronger and reduce the amount of Stardust and Candy required to Power Up, Evolve, or learn a new attack. Purified Pokemon have a special marker in the Pokemon storage screen, but they can be mass transferred, so be careful when selecting Pokemon for transfer.
Pokémon Go Purified Pokémon benefits
The Purified Pokémon will learn Return - a 3 bar Normal type move, which is great for Normal type Pokémon. IVs will be increased by 2 in every stat - Attack, Defence, HP. Finally, a Purified Pokemon's level will increase - the cap on this increase is level 25.
The IV increase means a Shadow Pokemon with IVs of 13 (13 attack, defense and stamina) are guaranteed to become perfect (100% IV) when purified. If it already has an IV 14 or more than that particular IV(s) will go to 15.
Return is retained by Purified Pokémon if evolved. Unlike Frustration, a Charged TM can be used to change it, and it would be overridden by event exclusive moves if applicable after evolution (even if a second charged attack is unlocked).
Purifying gives the Pokémon a significant increase in Combat Power and it will cost less candies to evolve. Make sure you Purify a Pokémon BEFORE you evolve it so you can use less candies.
Purifying a Shadow Pokémon adds two to each of your IVs (to a maximum of 15) and improves your Pokémon's level to 25. So, adding this information to your Pokémon's current stats will give you its new CP.
Purified Pokémon also get IV boosts when powered up. Each stat goes up by two when purified, meaning if you catch a Shadow Pokémon with at least 13 Attack, Defense, and Stamina will turn into an 100% IV Pokémon.
Is There Any Benefit To Keeping Shadow Pokémon? Trainers who choose to keep their Pokémon as Shadow Pokémon will reap the benefits of increased attack stats, but at the cost of decreased defensive stats. For some trainers, these stronger attacks are well worth the tradeoff.
A Purified Pokemon's CP level is boosted to level 25. This is beneficial in the event powering up a Shadow Pokemon past that level is resource-consuming for the player. The Pokemon's IVs will each be increased by 2.
Shadow Pokémon receive a 1.2x bonus to attack, whereas a Purified one will exchange that modifier for a few bonus IVs that don't provide as large a bonus. But as a tradeoff, Shadow Pokémon take more damage, are harder to level up, and can't unlearn Frustration outside of certain events.
The chance to get a 100% IV (15/15/15) Pokemon in Pokemon GO is 1/4096, or in percentage, 0.0244%. The chance to get any combination of IVs is the same and equals 1/4096. The game awards IV values using three random rolls, from 0 to 15.
As such, Eevee isn't generally considered one of the rarest Shiny Pokemon – it, or any of its evolved forms. It's unlikely that the first three forms are rarer than the last four forms, as they can appear without any special tricks or lures or any such stuff.
Shiny Pokémon remain shiny after being evolved. Also Pokémon cannot become shiny via evolving a non-shiny one.
It's easy to think that a super rare variant of a Pokémon would be much stronger than its normal counterparts, but the reality is, unless you're playing in Pokémon Gold, Silver, or Crystal, the answer is a definite no, Shiny Pokémon are not any stronger or weaker than normal Pokémon! Period. It's purely cosmetic.
