Library Unions – Complete List and Tips

In AFK Arena, the Library is where you can use your own Heroes or your friends’ Heroes to get more buffs for those exact Heroes in your team!

You still can use the assigned Heroes for all of the other activities in the game!

The old Library is crammed with countless tales written by the travelling bards of Esperia. Within it are the stories of many great heroes, some touching, others heartbreaking. They tell the tales of how great friendships and alliances were forged, brought together to fight against a common enemy. They are forever unbreakable…

Library/Unions Summary

• Choose a friend’s heroes or your own heroes to form a union.
• Different combinations of heroes can form different types of unions, increasing your formation’s total power.
• Higher tier Heroes are able to active stronger unions.
• You can select some of your heroes under “My Mercernaries” for your friends to borrow.
• If a player has not been online for over 7 days or a hero being used is lost, then that hero will no longer be available as a mercenary.
