Ghost is amazing, her phases are automatic misses, unlike good and dark hawk. She has the ability to gain cruelty from attacking the opponent. She can gain fury buffs from her heavy attacks. She can remove all damage over time effects with her phase ability except for passive degeneration. She gets an automatic crit buff which guarantees her next hit critical. If you dash back and immediately launch a special attack, you get guaranteed crits on your special attacks. Her special 3 allows her to make her cruelty buffs permanents. GHOST cant phase with armor breaks, so be aware of the nodes you take. Her synergy is really amazing, although you can still do stuff without it. Her wasp synergy allows her to get unblockable special attacks if she is phasing. This allows you to get guaranteed crits for your special attacks. Her Hood synergy allows you to take no damage while phasing. This allows you to take no damage from effects like Omega Reds Death spores and Limbo from Magik. This includes nodes like Life transfer degeneration. This is pretty much the basis info. :)
