What is the best method to grind out this trophy? Can I kill a bunch of guys while under stealth and then restart at a checkpoint to repeat the process - or will I lose my kill count doing that?
Do the kills still count if you die?
EDIT: What move counts as a stealth kill? Just to be sure I'm not wasting my time. From the tutorial you're supposed to hold
L2 to stealth, get close and then hold
SQUARE to attack? But sometimes he just swings and doesn't instant kill them, and the stealth is broken.
