Farm the Pure Bloom CE and the Star of Artoria CE from the quests, once you have at least one MLB Bloom and one regular Star (you can get those ones from getting Altrium), grab a Saber from your friends list who also has an MLB Bloom and you should be all right. Charge your NPs on the mooks before Scathach, and when you get to her quest, drop as many +attack skills as you can and blast through her and her friends. Also, the 3* CE can help you ignore her evade, if you're really having a lot of trouble with that.
