1. Can I get this Elo Overlay?

Yes, it is free to use. Check out the tutorial. Although it is free, I appreciate any small donation: You will need a key to use the overlay. You can get the key by logging in with Twitch in the Tutorial. If you have any problems, you can contact me on Twitter @deadofarceus or via Twitch whisper also @deadofarceus. Gerne auch auf Deutsch :)

2. What is Legacy Mode?

Legacy Mode is a feature that allows you to use the very old league Tier symbols (Diamond, Master, Challenger etc.).

3. Overlay Ideas or other programs to improve your stream?
