Don't get stucked and miss rewards! Progress faster

Dragon’s Lair (DB10)

After you have finished building your Giant’s Keep B10 team and farmed a lot of new runes, it’s time to take the next step: Dragon’s Lair – the second dungeon in Cairos Dungeon. It’s a really important dungeon, because the overpowered Violent runes are waiting for you there. For the most important rune set in the entire game you’ll need a reliable team which ensures safe runs, the Dragon has powerful skills and isn’t easily defeated.

You will want to bring multiple healers. Ideally, your healer has to have an AoE heal and the ability to remove harmful effects. This is because the Dragon will inflict Continuous Damage all the time, so you have to make sure you remove it to avoid getting wiped out eventually. Speed buff or debuff skills are also recommended.
