180 Viper at the new Monster Park

Ah, I see. I'll have to play around with it once the revamp hits GMS. Kinda sucks that you cant just use one skill to rush anymore then.

You can use just one. It just won't be as effective or fast. With the way the class plays now, using a single rushing technique at a time is kind of detrimental unless that one rush puts all of the mobs into one spot or within your line of fire.
