Unlock Factions when you reach 28,000 Might (Earl II).
First, go to “Shop” -> “Attack” tab and build the “Wardens’ Watch”.
Complete the simple trial and proceed to activate a Warden.
The Warden that you activate will give attributes boosts and help you in battle.
Tap the “Hero Faction” tab to view which Heroes belong to your Faction.
You can upgrade your Warden’s attributes, Subdue effect, and skill. After your Warden reaches Lv6, every 2 levels of attribute and Subdue raised will also raise its skill by 1 level.
Level up each Warden with their corresponding Birthrocks. Clear relevant Forgotten Trial stages to obtain Birthrocks.
To be continued.
