Effect
When the attached card is played, a random effect triggers. Like rolling a dice, each play produces a different result — ranging from coin gains and bonus damage to various buffs. The unpredictable nature makes it hard to plan around, but the upside when a strong effect triggers can be significant.
Unlock Condition
The exact unlock condition is unknown. It is believed to be unlocked by completing a specific run or fulfilling a certain in-game condition.
Best Cards to Attach
Best suited for casual builds that embrace randomness, or as a bonus attachment on cards already well-served by other gems. Avoid placing it on critical combo pieces where consistency matters.
Tier
Tier C — High variance and low reliability. Powerful when a great effect rolls, but difficult to incorporate into a consistent strategy. Better for fun-focused play.
