Mars - Fox-Masked thieves trying to stop Elsword from stealing the El! They shouldn't be a problem as long as you quickly attack them.
Ruchi - A bird who accompanies the thieves and tries to attack Elsword and his team.
Toto - One of the many thieves that tried to steal the Elstone. They can attack from distances using their knives.
Fairy Guardian - A misplaced relic guardian that attacks anything that gets close. These monsters will appear on the ground and rises as you approach them. They cannot be launched or knocked down.
Tree Knight - Like the Ruchi, the Tree Knight also accompanies the thieves.
Bruce - One of Banthus's strongest thieves. You'd better watch out for his club!
