>>36253399It's a percentage boost, so it depends on the EVs and IVs, not just the flat base stat value. To give some idea of the range, here are both ends of the spectrum (these assume the Chansey has max IVs in the stat).
With no EVs in either, Eviolite Chansey is equivalent to a Pokémon with:
- base 16.5 Defense
- base 166.5 Special Defense
With full EVs in each, Eviolite Chansey is equivalent to a Pokémon with:
- base 31.75 Defense
- base 182.25 Special Defense
