Everything you need to get started
Overview
lolsummd lets you combine the champion mastery data of multiple League of Legends accounts into one unified summary.
You can add up to 10 accounts at a time from any region.
✦
Instructions
Add accounts by entering a username and tag. For example, SummonerName#NA1 splits into SummonerName and NA1.
Alternatively, you can copy paste in something like username#tag and it will split them for you.
The TAG field will default to the standard tag for the selected region if left blank.
Once you've added your accounts, click Get Combined Mastery to retrieve the aggregated data.
Remove individual accounts with the Remove button, or wipe the whole list with Clear All.
✦
Sharing

Your accounts are also saved automatically in your browser. When you return to the site, your last used accounts will be restored so you don't need to re-enter them.
