i found that the char doesn't resummon the guard like the old days so , i suggest to :
put your Guard Name or monster i.e. SilverGuard etc.. in the Monsters names to kill blank > put 4 in the "plvl around" > put 4 on plvling step ..
this will make the player walk few steps after each summon and don't forget to put the guard icon summon of F9 and sit on F10 ..voila
