Giant’s Keep is the first dungeon in Cairos Dungeon and it’s the first one to farm. After you begin your Summoners War journey and progress through the Summoners Way, there’s no way around Giant’s Keep.

Farming Giant’s Keep is one of the essential parts at the beginning, you will get your first runes to build up your monsters. Therefore it’s really important to build teams with a 100% success rate. Giants B10 drops especially strong PvE Runes and it’s your next step after clearing the Summoners Way. Unlike other dungeons, GB10 is perfect and easy for your beginner monsters and you can build your first dungeons teams. Keep in mind that slower and safer teams are better than faster teams that regularly fail. We recommend farming GB10 some time after you’ve reached a safe status and you can farm without any fails. You will need a lot of new good runes for your monsters to be able to farm the next dungeons Dragon’s Lair and Necropolis. Most of the GB10 teams are F2P and beginner friendly and therefore easy to build.

Ancient Giant Boss Details

The boss has two crystals by his side. The left crystal will strengthen the attack power of the boss. A buff removal unit can come in handy. The right crystal will decrease the defense of all your monsters, so a cleanse unit is not just handy but necessary. The ancient giant can use the following skills:

  • Rockslide – Causes a rockslide to attack all enemies. This attack has a fixed chance to stun them for 1 turn.
  • Great Earthquake – Causes an earthquake to inflict great damage on all enemies, also reducing their Attack Speed for 3 turns.
  • Fend Off (Passive) – Counterattacks the enemy immediately after the 7th attack. [Automatic Effect]

These buffs and debuffs are very good against the boss

  • Cleanse
  • Heal
  • Attack Buff
  • ATB Reduction
