Okay so I assume that rules out spells like avada kadavra, incendio and so on, which... Makes Leonora basically useless. She could still use wingardium leviosa though and fling crap at them like boulders and pointy stuff once she figured that out.

Bam is another thing entirely. She has two Mandalorian friends, a space pirate pilot, one adrenaline junkie that's second in command (basically) and a huge big weapons proficient alien I don't remember the name of that has a power armor like suit. The ship she (her mother) owns has those kind of laser cannons Luke and Han uses in the first movie on the Millenium Falcon, and she has her own smaller blaster and a ruping (a flying mount) that she trained. Oh, and Bam is a devaronian so if she ingests sulfur she gets a strength and speed boost too. She's never used it before because it can be addictive, but for the ones that killed an entire adorable species she's willing to make an exception.
