Exactly what guy above said.
After first combo i use Chameleon Cloak (invisibility) means enemy cant see me so they cant do anything, they pass. Its my turn again so i attack from stealth, then using Time Warp (Time Warp gives you second tour just after you finish it) that means i got third tour without enemy doing anything. Next i use Playing Death, if you're alone it completely resets the fight (you're going out of combat) so you attack, combat starts and its again your tour.
That means 4 tours of your attacks without Enemy doing any damage to you.
Playing Tactican mode and actually if there are 3 enemies, i can kill them without making them even more. If 4 or more then they actually can attack me.
And about your question, most of the times backlash>all in destroys enemy psychical shield, but to do that you must always look what merchrants selling to get best daggers you actually can.
