Stand diagonal to them as you would with a Dragon Lord. If not careful, their lethal combos can bring down even decent High Level players. Sometimes it is very hard to outrun them in pack due to their Paralyze ability. They have the ability to kill a Level 100Mage in one combo. Mages should use Magic Shield and attack with Energy-based Attacks. It is also recommended to use Glacier Set as protection for the avalanche attack, and a Garlic Necklace to protect against its wave attack. Knights should avoid the waves and heal all the time to remove Paralyze and be able to move fast, when the Frost Dragon run away, shot Exori Hur to kill faster and avoid lure more. Paladins must run but use walls to trap it, because you can lure other Frost Dragons and Frost Dragon Hatchlings. All vocations should run diagonal as their Paralyzing Ice Wave is very dangerous and can easily lead to your death.
