Cooldown reduction is your best friend with her. Run her with as many cooldown reducers are you can fit into a team. Also, make sure to run her with units that have AoE Slow, Stun, or Immobilize. Slow would be preferable as it last a little longer typically than the others (not always). This is to ensure that you get the benefits for 100% ignore defense on Skill 3.
Adept is hands down the only set option for her. So make sure you have some nice pieces for use. Once you have the correct team she will really shine. In addition her buff strip and Mortal wounds make her a terror in PvP.
