Phantom is the new Thief Hero you can choose in KMS. This new job allows the player to steal skills from another player. Although you can only steal from Adventurers/Explorers. Also the skill has to be non-passive. Phantoms can steal party buffs and attacks. They cannot steal passive skills or skills like Flash Jump and Teleport. So skills like Bless, HS, Haste, and HB would some good buffs to steal. :D In the video, I stole a Gunslinger and Bowman's double shot attack.
