Where do CR boxes come from?
You get them from CR quests. Chill CR Box drops during chill hours, Prime Time CR Box in the evening, and Mob CR Box from Mob CR quests. Each CR quest also gives 1 CR Point. Box contents change with the Tuesday and Friday updates, so the odds here reflect the current list on the site; right-click a box in game to check it yourself.

What are the odds on +5 Shell pieces?
