Resonating Crystal

The Resonating Crystal is a place at the Ranhorn in AFK Arena. This is where the player's five best heroes are set in the Pentagram. It is unlocked after completing 4-36 in the Campaign Mode.

The slots available are for the other heroes from the roster: the player chooses which one is to be raised to the level of the lowest hero in the Pentagram.

While in the slot, a hero cannot be leveled up the classic way in the Hero menu.

When removing a hero from a slot, there will be a cool down of 24 hours before the slot is available again, however the cool down can be skipped by paying 100 Diamonds.

More slots can be unlocked using Invigorating Essences. Invigorating Essences can be found harvesting AFK Rewards after finishing Chapter 5 and by completing campaign quests rewarding it (e.g. level up your heroes on the crystal to a specific level).


Levelling up your crystal.

After reaching level 240 with all your heroes on the Crystal leveling single heroes won't be possible anymore. Instead, you will be able to level up the Crystal itself in effect leveling all heroes currently in slots.

The maximum level of your crystal will be determined by the number of heroes ascended to Ascended level (white/crystal frame), each hero giving +5 maximum levels (e.g. when you have 5 ascended heroes your maximum level of the Crystal is 265). Currently, the maximum level of the Crystal is 410, it will be increased when new Ascended tier heroes will be added to the game.

Upgrading Crystal at Lv. 240

Rk raise button

Once the top 5 heroes are leveled up to 240, a new button will be added at the bottom of the interface where you can raise the limit of the maximum level.

Clicking this button will play an animation and permanently modify the resonating crystal interface:

Rk after upgrade
  • 5 more slots are added to the Resonating Crystal.
  • 5 heroes atop of the resonating crystal are removed and assigned to these slots.
  • Curved progress bar is added below the Resonating Crystal instead of heroes.
  • A new Strengthen Crystal button is added to the bottom of the interface.

Strengthening Crystal Beyond Lv. 240

For each ascended (white) characters in your possession you can increase the crystal level (and level of all characters added to crystal slots) 5 more times. Since you need at least 5 chars to be ascended in order to have 5 240 chars this gives you a minimum available level as 240 + 5*5 = 265.

Rk lvl up

Click on the "strengthen crystal" button at the bottom will spend specified amount of gold and hero exp and increase the curved progress bar below the crystal. You need to strengthen crystal 10 times to level it up, with each strength increase cost the same amount of gold and hero exp, but last one also has an additional cost in hero essence.
