Shiny is a rare variant of Mythic and Divine layers. The Chaos Luck pass (99 Robux) makes those layers 1.5x more likely to come out Shiny on every banner. It does not raise your chance of rolling a Mythic or Divine in the first place.

FAQ
What is Chaos Luck in Bey Rivals?
A 99 Robux game pass. Every Mythic or Divine layer you summon is 1.5x more likely to come out Shiny, on every summon and every banner, forever.
Does Chaos Luck increase Mythic odds?
No. It only raises the chance that a Mythic or Divine layer you already rolled is Shiny. The Mythic (0.5%) and Divine (0.01%) rates stay the same.
Is Chaos Luck worth it?
Only if you care about Shiny looks and already pull Mythic layers. For power, put Robux into Spin Tickets or VIP instead.
