About Cookie Run: Kingdom Treasures
Treasures act as buffs for your team that come in the form of Passive or Active buffs. Passive buffs are always in effect while Active needs to be activated and the last for a set amount of time with a cooldown once used. Passive are naturally powerful but Active can outperform them when used at the right time.
Treasures can also come in 3 different qualities: Common, Rare, and Epic. Common is the most common to receive, Rare is the next most common, and Epic is the most rare to see. Just because a treasure is more rare than another doesn't necessarily mean that it's better. For example, Squishy Jelly Watch is a common rarity treasure but is also one of the most sought after due to its effect.
This page holds all of the stats for all of the treasures in Cookie Run: Kingdom so you can see which ones you want to use in your party.
