Reminder of higher Gemstone drop rates during MSI

I found out a number of my league friends didn't know this either so I wanted to post it for everyone. During MSI match days you can purchase MSI hextech chests (600 RP). Inside are three skin shards, yes only skin shards. One is a guaranteed Esports skin shard, the other two are randomized skin shards. There is a cap on how many you can buy per day (25). When you open a chest you will know if there is a Gemstone as there will be four loot diamonds instead of three (little markers under the shards in a normal chest).

tl;dr These MSI chests have a 50% Gemstone drop rate increase
