Prism Ball is the highest-tier capture ball in Roco Kingdom: World. A successful Prism Ball throw guarantees the capture, produces a Shiny and Variant Spirits form, and locks the spirit at the Excellent talent tier. Because it bypasses every part of the normal capture and rolling system, Prism Balls are the most valuable seasonal premium resource in the game and player guides treat their accumulation as a core long-term goal.
Prism Balls are crafted from Prism Ball shards. Shards drip in from several recurring activities, and the daily and weekly caps make consistency more important than any single high-payout source.
Source | Reward | Cadence |
|---|---|---|
Daily Stamina Exchange (2 stamina to 1 shard rate) | 60 shards per day | Daily, repeatable |
Hero Medal Codex (Destined Flower Seed content) | 1,200 shards | Once per two weeks |
Starlight Showdown event clear | 200 shards | Weekly |
Free Season Pass track | 400 shards | Once per season |
Paid Season Pass track | 1,600 shards (replaces free track) | Once per season |
The shards-to-Prism-Ball conversion scales with the number of shards the player accumulates between season resets. Player community estimates of total Prism Balls earnable per season at three common investment levels:
Investment Level | Prism Balls per Season |
|---|---|
Free-to-play, daily login only | approximately 6.35 |
Monthly Card subscriber | approximately 11.6 |
Paid Season Pass holder | approximately 12.35 plus cosmetic rewards |
Other top-tier capture balls also guarantee captures, but Prism Ball is the only one that also guarantees the cosmetic and stat outcome. The relevant comparisons:
King Ball: 100% capture rate, no shiny or talent guarantee. Costs Roco Diamonds or comes from Kingdom Castle gacha attempts.
Capture Light Ball: 100% capture rate, no shiny or talent guarantee. Bought from the Light-Collecting Pass Season Hall exchange.
Rainbow Ball: 100% capture rate plus a perfect-nature guarantee, no shiny guarantee. Used with specific items.
Prism Ball: 100% capture rate, guaranteed shiny variant, guaranteed Excellent talent.
Because Prism Balls are limited per season and the captured spirit is automatically shiny with Excellent talent, players generally save them for spirits whose Shiny Farming Guide route is otherwise inefficient. Common Prism Ball targets:
Hidden rare spirits with one-time spawns, where a missed standard catch cannot easily be retried.
Boss-form spirits that have very low base capture rates outside of their event windows.
Personal favorite spirits whose shiny variants have low natural drop rates relative to playtime budget.
Treat the daily 60-shard stamina exchange as a non-negotiable login chore. Skipping a day costs roughly 6% of the season's free income.
The Hero Medal Codex is biweekly, not weekly. Set a calendar reminder for the second week so the 1,200-shard payout does not lapse.
Save Prism Balls until the targeted spirit is actually in front of the player. Hoarded Prism Balls do not roll over indefinitely between major patches; check the Patch Notes for any expiration changes.
