Raigo is a tool to automatically optimise gear selection for Raid: Shadow Legends.
First check out the repository and install the dependencies:
$ git clone https://github.com/bgrozev/raigo .
$npm install
Edit input.js to specify your account stats (great hall bonuses), select
the champion to optimize for, the minimum required stats, and the stat to optimize.
You may need to add your champion to champions.js if it's missing.
Raigo operates on a list of items in CSV format. The format is described in this google sheet. You can just copy thee sheet, add your items, then download in CSV format.
After saving your gear in gear.csv, run raigo with node main.js gear.csv
