You can use your heroes, friends’ heroes, guildmate heroes to form a union and activate a powerful buff, which can increase the HP, ATK, ACC, etc. stats of the heroes instantly.

Heroes in the union get massive buff from the union perks. So if you are having trouble passing a stage, you should spend some time in creating unions.

AFK Arena Library & Unions Guide⇓

AFK Arena Library & UnionFirst, let’s take a look at the list of unions and the heroes that you need to create for that specific union: –

  • The Gallant Three – Morvus, Hogan, Angelo. You need these three heroes to create this union. And, these three comrades will get buffs passively. We’ve shared an example below; make sure to read it. You can use a friend’s hero as well as a guildmate hero. So, it’s important to join an active guild with loads of members.
  • Defenders Of The Forest – Ogi, Nemora, Arden
  • The Dusk Patrollers – Ira, Lyca, Kaz
  • Master & Apprentice – Brutus, Kasos
  • Arcanists Union – Isabella, Vedan, Silvina
  • The Dragon Slayers – Vurk, Numisu, Saveas
  • The Wrathful Two – Grezhul, Thoran
  • Wisdom & Hope – Tasi, Ulmus
  • Castellans – Thane, Estrilda
  • The Lightbringers – Belinda, Lucius
  • The Bounty Hunters – Fawkes, Mirael, Raine
  • The Sisterhood – Safiya, Ankhira

Go to the castle buildings menu -> tap the library -> here you can check all the unions. Tap on any union and you can see the heroes(their portraits) that you need to form that union. Now, if you have these heroes, tap the + button to slot them. At the bottom of that screen, you can also see the buffs and the requirement to activate buffs. By creating a union, you can enjoy three types of buffs. In the first one, you can use any rarity heroes. To activate the second buff, you will need elite rarity heroes. And, at last, for the last & third buff, you need legendary heroes.

So that’s how AFK Arena Library & Union function works. Now, let’s learn with an example; AFK Arena Library & Union buffs: –

  1. Very helpful Guide, however, the bit that I really wanted to know was: what is the number that is at the base of each portrait of the Unions? All mine say 0/2 or 0/3 but some have all three slots filled and functional so I have no idea what the nember is referencing. Any idea?
