One in the picture is his first blade and soul gold
Gubong has 2 forms, the one in the picture is his first. Once everybody is buy Blade and Soul items ready go ahead and start beating him down. His skill range includes, a grab you cannot block (he generally targets the person with the most aggro) one big aoe attack – this is a charge up aeo and can be dodged very easily, a one sided aoe attack (again dodges easily) and also a buy Blade and Soul items jump attack where he goes up into the air and lands on whoever he has targeted.
