How to Upgrade Eureka

Access Eureka Upgrade From Your Pear-Pal

Pear-Pal Guide

Upgrade With Bling and Shining Particles

Eurekas primarily cost Bling and Shining Particles to upgrade. While Bling is abundant in the open world, Shining Particles can mainly be obtained from the Mira Journey Battle Pass starting at Level 14 and appearing every 5 levels thereafter. However, The paid track of the Battle Pass will offer more Shining Particles.

Use your Shining Particles wisely, as their availability is limited. Once you are happy with your selection, select the Upgrade Button at the lower right corner of your screen to initiate the upgrade and increase your Eureka's attribute.

Other Eureka Can be Used as Upgrade Material

If you find yourself running out of Shining Particles, you can use other Eurekas as the upgrade material instead. For this, it is recommended to invest in your best 5-Star or 4-Star Eurekas and use your 3-Star Eurekas as the upgrade material.

Do note that when Eurekas are used to upgrade another, they will be permanently deleted and cannot be retrieved. Be sure to choose your Eurekas wisely and lock any important ones for safekeeping!

Quick Add Upgrade Materials

You can use the Quick Add feature to streamline upgrading your Eurekas. Adjust the filter in the dropdown menu to select a rarity range, which is set to Below 5-Star by default. To clear all selected Upgrade Materials, click the broom icon next to the dropdown menu.

How to Get Eureka
