Welcome to

Ganjilla's Idle Heroes Campaign Drop Calculator

What is this? This is a tool for the mobile game Idle Heroes, which you can use to figure out your chances of obtaining the highest tiers of loot from the campaign drop event which comes around once a month.

Note from Ganjilla!

What's up idlers? Oh, Shadow Graveyard and it's spoils. Your chance at the reworked Jahra and Xia and even that Siggy skin. Let's jump right into it and as usual, the BEST of luck to y'all.

Cheers, Ganji.
