[stealth] cheapshot ( stuns for 4 seconds) lvl 26 you get it. Sinister strike tille 5 combo points, [/quote]

I seriously doubt that "sinister strike till 5 combo pionts".
you are not able to regain energy even when u use 2 sinisters before stun breaks....  so... kidney after 1st sinister ro 2 sinister strikes and give the enemy chance to make a move.
Just my opinion. 5 cp only with premed.
