The most fun I've had with a set of ability + skill EVER.
Her AMP skill does pretty much no damage from the get-go, but you can use Ctrl to use her EM Sonar ability! Her cute sonar will go in search of surrounding enemies, charging up her AMP skill for a bit of time. Lethal in long fights and against many enemies, as you'll charge up her (cheap) AMP skill more and more!
