Formula Used
Purified IV: min(15, Shadow IV + 2) for attack, defense, and stamina.
IV percentage: (Attack IV + Defense IV + Stamina IV) / 45 × 100.
Purified level: max(Current Shadow level, 25). The calculator keeps a higher existing level.
Estimated CP: floor((Attack × √Defense × √Stamina × CP multiplier²) / 10). Attack, defense, and stamina include base stats plus IVs.
Shadow attack index: (Base attack + Shadow attack IV) × (1 + Shadow attack bonus).
Shadow bulk index: ((Base defense + defense IV) × (Base stamina + stamina IV)) / damage taken multiplier.

Shadow Purification Planning
Why this calculator helps
Shadow Pokemon can be confusing. A strong Shadow attacker may outperform a purified version in raids. Yet purification can create better IVs, lower upgrade costs, and unlock Return. This calculator helps you compare those outcomes before you tap the purify button.
What purification changes
Purification raises each IV by two points. Each stat stops at fifteen, so a 14 attack becomes 15, not 16. A 13/13/13 Shadow becomes a perfect purified Pokemon. The tool also raises the displayed level to at least level 25. If your Shadow is already above level 25, the level is kept.
Cost and resource planning
Purification costs depend on the species group. Common options may cost 1,000 Stardust and 1 Candy. Many Pokemon cost 3,000 Stardust and 3 Candy. Higher groups can cost 5,000 Stardust and 5 Candy. Shadow legendary Pokemon usually cost 20,000 Stardust and 20 Candy. The calculator lets you choose a tier or enter a custom cost.
Battle value comparison
Shadow Pokemon gain a damage bonus, but they also take more damage. That makes them strong for fast raid damage, but less forgiving in some battles. Purified Pokemon lose that Shadow bonus. They gain cleaner IVs and cheaper long-term development. The calculator shows a simple attack index and bulk index. These are planning indicators, not official rankings.
How to read the output
Look first at the purified IV line. If all three stats become fifteen, the calculator marks it as perfect. Next, review the IV percentage change. Then compare your Stardust and Candy balance. Finally, check the recommendation note. It explains whether the Pokemon is mainly a hundo candidate, a low-cost research choice, or a possible Shadow keeper.
Smart trainer advice
Do not purify every Shadow immediately. Save cheap purification choices for research tasks. Keep rare high-attack Shadows when raid value matters. Purify when you need a perfect entry, Mega eligibility, Return, lower upgrade costs, or a collection goal. The best decision depends on your Pokemon, resources, and play style.
Use this page as a planning guide, not a promise. Game updates, move changes, and league metas can change value. Recheck important choices carefully before spending resources today.
FAQs
What does purification add to IVs?
Purification adds two points to attack, defense, and stamina IVs. Each stat stops at 15. A 14 IV becomes 15, and a 13/13/13 Shadow becomes 15/15/15 after purification.
Can this calculator find a purified hundo?
Yes. Enter the Shadow IVs. The result shows whether the purified Pokemon becomes perfect. Any Shadow with at least 13 in all three IV stats becomes a purified hundo.
Does purification always improve battle performance?
No. Shadow Pokemon often deal more raid damage. Purification improves IVs and bulk, but removes the Shadow attack bonus. Compare the indexes before deciding.
Why does the tool use level 25?
Purified Pokemon are raised to at least level 25. If your Shadow is already above level 25, this calculator keeps the current higher level.
Are the CP results exact?
They are estimates based on base stats, IVs, level, and CP multipliers. Enter accurate base stats for the species to improve the result.
Which purification cost should I select?
Select the tier shown in your game. Common choices include 1,000, 3,000, 5,000, and 20,000 Stardust tiers. Use custom fields when needed.
Should I purify legendary Shadow Pokemon?
Be careful. Legendary Shadows can be rare and strong. Purify only when the perfect IV, collection value, Return, or personal goal matters more than Shadow damage.
Can I save my result?
Yes. After calculating, use the CSV or PDF download buttons above the form. The files include key IV, cost, CP, and recommendation values.
