Maladi held off Shado Vao with lightning and maybe a bit of saber (she's described as agile, and while she was carrying a saber most of her defense seemed to be holding Shado's saber back with lightning), and hit Cade Skywalker with a memory walk (a strong ability!).
Cade managed to overcome the 'walk and hit her with one of his own, so she force-pushed him and escaped.
Also Nihl seemed to think if the two got involved, they'd likely destroy each other, but that may just be their skills at treachery.
