Supportive Clarisse (NO x-sweep)

As the title suggests, I'm looking to build a supportive Clarisse but I'm (mostly) F2P and don't have any sweep anything (skills or weapons). I already have a 5* +ATK Klein for offensive work, but my play style is better suited to enemy phase and baiting than super offensive nuking (basically: I'm timid). I've had a lot of fun levelling her and would like help developing a budget build that takes advantage of her base kit and bow. Any suggestions?
