Sister of Captain Britain, Betsy Braddock is the psychic X-Man known as Psylocke. Originally just a telepath, Betsy ended up switching bodies with a deadly assassin that allowed her to become the psychic ninja she is today. Psylocke uses her telekinetic powers to manifest a "Psi-Knife" and her trained ninja skills to slip into the shadows and cut enemies down with her martial arts and katana skills.Marvel Source
The rest is mostly single target stuff. I chose as the basic to build up . Single target abilities include for the DOT, for the buff, then for the rest. On long fights, or mobile fights (which may not be the best dps but it's fun to me nonetheless), it's a balancing act between spirit and psi energy. You can use when you have a lot of spirit, when you have little spirit, but a ton of Psi Energy, and to allow both to recharge. Use whenever it's up! Use Magik on passive.
The awesome thing about this build is you have a great escape tactic that still pumps out some damage. When in trouble, away from the boss, then follow it with . Your projection will still hit for a good amount (thought not nearly as much as you doing it yourself), and draw aggro while you all your healing to take hold.
