About PS Randbats Assistant
Get a clearer view of your next turn in Pokémon Showdown.
PS Randbats Assistant adds a compact, minimalist sidebar to Gen 9 Random Battles, with damage estimates and possible-set tracking alongside your battle.
• Hover over or keyboard-focus your move buttons to see outgoing damage estimates.
• Compare incoming damage from revealed and possible opposing moves.
• See stat boosts reflected in damage estimates.
• Track revealed items, abilities, Tera types, and remaining possible sets.
• Expand estimates to inspect assumptions about unknown items and abilities.
• Collapse the sidebar whenever you want more space.
Item estimates use sampled Pokémon Showdown team-generation data and narrow as opposing moves are revealed.
LOCAL PROCESSING
Battle information is processed locally in your browser. No analytics, advertisements, or extension account. All executable code and calculation data are bundled with the extension.
SUPPORTED FORMAT
Gen 9 Random Battles singles on play.pokemonshowdown.com. Reload Showdown after installing, then start a new battle.
ESTIMATE LIMITATIONS
Damage estimates depend on available battle information. Unknown items and abilities are assumptions and not confirmed. Sampled item frequencies are not exact probabilities. Some unusual mechanics—including Substitute, Transform, and ability suppression—are not fully modeled and may have minor issues.
