Perfect IV Values for Sinistea in Pokémon Go
A flawless Sinistea requires 15/15/15 IV ratings to achieve peak performance in competitive battles and collection purposes. For trainers Level 30+, optimal CP values are:
- Level 35 (weather-boosted) – 1057 CP
- Level 30 (standard wild) – 976 CP
These thresholds assume standard spawn mechanics post-Trainer Level 30 adjustments. Lower-level trainers will encounter different CP ranges.
Acquisition Methods for Rare Variants




Wild encounters remain the primary method to obtain this rare variant outside special events. While Spotlight Hours or seasonal rotations might temporarily increase spawn rates, standard odds apply unless explicitly stated otherwise. With approximate base rates of 1:500 encounters, persistent exploration is advised for collectors.
Encounter Probability Analysis
Odds of encountering the rare variant fluctuate based on acquisition methods. Regular wild encounters typically follow base rates (~1/512), while Raid Battles during recent events offered improved odds (~1/128). Consult community-maintained databases for current rate adjustments.
Visual Characteristics of Rare Forms
The transformed Sinistea exhibits a striking lavender hue replacing its original teal coloration. This chromatic shift persists through evolution to Polteageist. Notably, the distinguishing stamp beneath Antique-form specimens retains its default coloration regardless of variant status.




Availability Status
Since its late October 2025 introduction, the rare Sinistea variant has been obtainable for dedicated trainers. Recent Raid Battles temporarily enhanced encounter rates, though standard conditions now apply. No Community Day event has occurred for this species to date.
