While running through the dunes I already improved my reputation with Sand Ninjas- but how does one persuade enough Sand Ninjas attack the same town at the same time? Lazy as they are, you would have to carry them there...
Searching for incapacitated Ninja Jounins, bandaging them and carrying around until every squad member has one on his back would take too much time so I decided to pick up regular Sand Ninjas too. (might have given them better weapons if I knew how much trouble they'd have with shop guard 1v1)
My plan was to carry them to Catan and let them kill everything but Catan was too well guarded! After my poor ninjas got knocked out I bandaged them again picked the survivors up and went looking for A "dead cat" town without police. (you cannot simply quickload to a position where you still carry the ninjas as loading will put them on the ground)
Even Mercenary guarded town proved to be too much for my twenty ninjas so I had to help them a bit by stealing weapons and medkits from the defeated defenders. After healing and picking up my black army three times the city was decimated.(and naked) My guys didnt lift their swordarms once.
Strangely enough at one point all inhabitants started running to a single building where they got slaugthered at one spot (40 bodies+) even if they got knocked midtown they went to the spot after they healed. Too bad nobody can really die in a city except maybe the vendors and ofcourse raiders.
My reputation with both ninjas and dead cat stopped growing at +19 which was a surprise as I read you need +25 to get allied(?). Anyway all Vendors "gave" me their black chainmail, most ninjas left the town but some kept killing the guards who revived.. also even in a dead town it was possible to trade with unmanned trade counters(and sell the looted guard weapons etc.).
This whole ninja exercise also had a pretty positive effect on my strength without really aiming for it.
