AFK Arena Library & Unions Guide: How It Works?

Updated on: March 1st, 2023

Release a passive buff to the heroes by creating unions in the AFK Arena game. Let’s learn how AFK Arena Library & Union function works

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. Once you clear a certain number of stages in the campaign mode, a new function called library gets unlocked. This function lets you form a union of heroes. 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. For the first time, it could be difficult to understand. If you are confused, then today’s AFK Arena Library & Unions guide will help you. Let’s get started!

AFK Arena Library & Unions Guide⇓

First, 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: –

Activating & Checking The Buffs⇓

As you can see in the below picture, Belinda’s total HP is 13405.

Belinda is part of The Lightbringers union. Now, as you can see in the below picture, we have activated the first buff by adding Lucius and Belinda to the slots. Now, the first buff has been activated.

After activating the union effect, you can see the difference in the HP stat of Belinda. It increases from 13405 to 14731(1200 HP+1%).

So as soon as you form the union, the heroes of that union get the buff instantly. If you have any questions, ask in the comment section below. So that would be all for our AFK Arena Library & Union guide for beginners. Also, see –
