Giant’s Keep Abyss

Giant’s Keep is the first dungeon in Cairos Dungeon and it’s the first one to farm. The Abyss dungeons are the next goal after clearing B10 dungeons efficiently. The Abyss version of the dungeons requires strong rune quality because the boss has higher stats and one of his skills is strengthened.

The Giant’s Boss has a lot of HP. Therefore, monsters with damage based on enemies’ max HP are essential to clear this dungeon. Monsters like Akhamamir or Wind Homunculus are F2P monsters that deal a substantial amount of damage to the boss.
