A dataset containing all available regions, hosts, and locales. API data is limited to specific regions. For example, US APIs accessed through us.battle.net only contain data from US battlegroups and realms. Locale support is limited to locations supported on Blizzard community game sites. Game information is different from region to region. For example, a user that has both US and EU WoW accounts has different characters, achievements, and other information in each region. Likewise, a D3 user who has a single license for D3 on their account has a different character list for each region in which the game operates.
regions
A data frame with 13 rows and 3 variables:
The region: us, eu, kr, tw, or cn
The host for example, https://us.api.blizzard.com/
