Process of converting a Shadow mons to a Purified form. Bumps IVs by +2 and lowers level by 2.
Process of converting a Shadow mons to a Purified form. Bumps IVs by +2 and lowers level by 2.
Purifying a Shadow mons removes the 1.2× damage / damage-taken modifiers, lowers it by 2 effective levels, and bumps each IV by +2 (capping at 15). It also reduces power-up costs.
Cost depends on species — typically 1,000-5,000 Stardust + 1-3 candy per purify. Legendaries cost more.
The IV +2 bump means a Shadow with 13/13/13 base IVs becomes a Purified hundo (15/15/15). This is why "purifying for the hundo" is a real strategy — but only if you don't need the shadow attack bonus for raids.
Shadow IVs floor at 6/6/6 (raid floor +0). Add +2 from purify = 8/8/8 minimum on a purified mons.
A Shadow with 13/13/13 base purifies into 15/15/15 = an instant Purified Hundo.
