Assassins received training from an early age and as well as the more obvious stealth and combat skills training they were also trained in free-running and tactical thinking such as observing their surroundings and planning ahead. Once again both of these warriors have received extensive training. Both are effective and both the Ninja and Assassin are equally good at stealth. Ninjas on the other hand made more use of disguises to blend in with civilian populations and get close enough to the target to strike. The Assassins preferred style of attack is to blend into the shadows, striking from behind or from above and them disappearing away into the background. As expected both of these groups of warriors are masters of stealth and are specifically trained to kill silently and disappear without a trace.
