The Global Chat in Mythic Heroes is where you are going to find your new in-game buddies who will even be able to help you summon new Heroes! Join the Global Chat and start adding players as Friends so that you can start sending and receiving Friendship Points! Use these points in the Summoner Sanctum to summon Heroes to join your team.
The Global Chat will also be your main way to find Guilds that are recruiting members. Guilds will unlock during the Campaign and will offer you many more ways to earn rewards, including fighting the Blade Wraith and joining in large-scale battles with your Guild in the Coliseum!
Once you have joined a Guild, you will see that you gain another channel inside the chat feature. This channel will be for you and your Guild to plan your attacks or just hang out.
