A new “Gems of War Factions” discord server has been established and is up and running! The server moderators gather information from other members who have submitted their data and have created a crowd-sourced difficulty ranking for factions. The server has teams, videos, charts and spreadsheets other useful information regarding delving in general!
This really is a useful server to have. The team there are really helpful, supportive and full of tips to help you beat those factions.
They have a great chart on faction completed with what level hoards that has had so many users input data into it. So you can be confident going into a pure run that over a dozen others have done the run with that level hoard and it wasn’t just luck.
