Strategic guide on purifying Shadow Pokemon in Pokemon Go: when to purify for perfect IVs versus keeping shadows for PvP battles.
The Great Purification Debate: A Reddit Case Study
Pokemon Go enthusiasts experienced a wave of mixed emotions when a Reddit user revealed they had purified their Shadow Articuno, transforming it into a specimen with perfect Individual Values (IVs). This decision sparked intense discussion within the community about optimal gameplay strategies.
The Pokemon Go community on Reddit found itself divided after a player purified a Shadow Articuno, ultimately receiving a perfect 100% IV appraisal as a result of the process.
Since Team Go Rocket introduced Shadow Pokemon to the game, trainers have continually explored strategic applications for these powered-up creatures. The shadow mechanic adds a compelling layer of complexity to team building and resource management.
Player versus Player (PvP) enthusiasts have identified specific Shadow Pokemon that excel in Go Battle League formats, leading many competitive players to adopt a ‘never purify’ philosophy for their most valuable shadow catches.
One trainer shared their experience on the Pokemon Go subreddit, revealing they had purified a Shadow Articuno. The community response highlighted the ongoing tension between different playstyles within the game.
On July 27, 2023, user axl_hiu posted their exceptionally rare acquisition to the Pokemon Go subreddit. The accompanying screenshot displayed a purified Articuno with perfect IVs, commonly referred to as a ‘hundo’ by the community.
“The shadow was almost 4* so I purify it!!!,” the original poster explained. When trainers purify Shadow Pokemon, each IV stat (Attack, Defense, and Stamina) receives a fixed increase of two points. This systematic boost can transform near-perfect shadows into flawless specimens.
This mechanic means that if a Shadow Pokemon’s appraisal is sufficiently close to perfection according to your preferred Gym Leader’s evaluation, purification can create a perfect IV Pokemon. Specifically, any shadow with IVs of 13/13/13 or higher becomes a 15/15/15 ‘hundo’ after purification.
However, many veteran players expressed uncertainty about this decision, having grown accustomed to preserving their shadow Pokemon intact for competitive advantages in Go Battle League matches. The community’s divided response reflects deeper philosophical differences about gameplay objectives.
Shadow vs. Purified: A Strategic Breakdown
“Who cares about meta choices, it looks so beautiful this way! I play mostly to collect, I would probably do the same,” one community member responded, highlighting the collector’s perspective that values aesthetic perfection and completionism over competitive optimization.

Another player offered strategic analysis: “Correct choice seeing as shadow Articuno isn’t useful in the current meta. And a shadow-perfect (shundo) legendary is at least a rare collection piece.” This comment acknowledges that not all Shadow Pokemon have competitive viability, making purification a sensible option for certain species.
A dissenting voice countered: “Fail. Should have left it shadow.” This perspective prioritizes the inherent 20% damage bonus that Shadow Pokemon receive, which often outweighs the IV improvements from purification in battle scenarios.
“I experience cognitive dissonance seeing good Shadow Pokemon getting purified,” a third player admitted. “Yet simultaneously recognize it’s an impressive achievement to obtain.” This ambivalence captures the complex emotional response many trainers feel toward purification decisions.
Performance Differences: The Numbers Behind the Choice
Shadow Pokemon operate as glass cannons: they deal 20% more damage but simultaneously take 20% more damage. This makes them exceptional for raids where dealing maximum damage quickly is crucial, but less optimal in PvP where survival often matters more. Purified Pokemon lose this damage bonus but gain cheaper power-up costs, requiring 10% less Stardust and Candy for all future enhancements.
When Purification Makes Strategic Sense
Purify when: (1) The Shadow Pokemon has IVs of 13/13/13 or higher, creating a perfect specimen; (2) The species has poor performance as a shadow in both PvP and raids; (3) You prioritize collecting perfect IV Pokemon over competitive play; (4) You need to conserve Stardust and Candy resources for other projects.
When to Keep Your Shadows Intact
Maintain shadow status when: (1) The Pokemon ranks highly in PvP or raid meta lists (like Shadow Mewtwo or Shadow Machamp); (2) You have sufficient resources to power it up despite higher costs; (3) You’re building teams for specific competitive challenges or short-manning raids; (4) The IVs are too low to benefit significantly from purification.
Advanced Player Strategies & Common Pitfalls
IV Threshold Calculations: Know Your Numbers
Advanced trainers should memorize these IV thresholds: A 13/13/13 shadow becomes 15/15/15 when purified. A 12/12/12 becomes 14/14/14. More importantly, understand that IVs represent only approximately 10% of a Pokemon’s total combat performance. The shadow damage bonus often outweighs even perfect IV advantages for many species.
Resource Management: The Hidden Cost of Shadows
Powering up Shadow Pokemon costs 20% more Stardust and Candy compared to regular Pokemon, while purified Pokemon cost 10% less. This creates a significant long-term resource differential. Before purifying, calculate whether you can afford to power up the shadow version to usable levels (typically level 30-40 for raids, level 40-50 for Master League).
Common Mistake: Purifying Everything Immediately
Many new trainers purify all shadows immediately to complete the purification medal or because they dislike the purple aura. This wastes potentially powerful battle assets. Instead, assess each shadow individually using online resources like PvPoke.com or GamePress’s raid attacker tier lists before making decisions.
Collection vs. Competition: Aligning Actions with Goals
Define your primary Pokemon Go objective. Collectors seeking living perfect IV dexes should purify high-IV shadows strategically. Competitive players focused on PvP rankings or short-manning raids should preserve shadows of meta-relevant species regardless of IVs. Casual players should consider which approach brings them more enjoyment.
Optimization Tip: The Two-Shadow Strategy
For legendary shadows obtained from Giovanni, consider this advanced strategy: If you obtain two of the same shadow legendary, purify the one with higher IVs (13/13/13+) for your collection, and keep the other as shadow for battles. This approach balances both collection and competition goals.
Actionable Framework for Your Decisions
Despite the spectrum of community opinions, the original poster expressed satisfaction with their choice to purify their noteworthy catch. This underscores the personal nature of these decisions in a game with multiple valid approaches to enjoyment and achievement.
Your Personal Decision Matrix
Before purifying any Shadow Pokemon, ask yourself: (1) What are this species’ rankings in current PvP and raid metas? (2) Are the IVs 13/13/13 or higher? (3) Do I have resources to power up the shadow version? (4) Which brings me more satisfaction—a perfect IV or a powerful attacker? Your answers will guide optimal decisions.
Long-Term Planning Considerations
Remember that Pokemon Go frequently rebalances combat mechanics. Today’s weak shadow might become tomorrow’s meta king after a move update or stat rework. When uncertain, consider waiting for Community Day announcements or seasonal updates before purifying rare shadow specimens, especially legendaries.
