► Playlist with playthrough: • [DS] Megaman ZX Advent Ricochet buster is fun. Kind of. Boss: Rospark - 02:55 Spidrill is easier with Ashe since her Ricochet Buster helps a lot dealing with this stupid thing. Using Chronoforce to shield yourself from the spark rain attack is also very helpful. Ashe's charge shot make the fight against Rospark easier since she doesn't have to move in front of Rospark to shoot him, this leaves her with much more time to dodge attacks in general. Anyway, you have no idea how difficult is to dodge Roskpark's desperation attack (the triple ray beam) standing between them until you try it yourself.
