Doesn't take long, and you get a good save. Done it many times with up to 4 enemies.
Important: turn on "confirm attack" before you try. That way you can savely bump into them, cancel the attack and immediately save.
4 gargoyle guys or imps right next to you, and you can mass up kills insanely fast.
Oh, and in case you like min/maxing, you try to get the right angle as well
Since I use my right thumb, I make sure that at least one marked enemy is in the lower right corner of my character and bottom and right have a wall and another enemy. That way I have short tipping ways for my thumb and cannot accidentally walk past the mob.
Further min maxing: save in the save slot that is in the same spot as the "load game" option. For my phone it is slot 10.
That way, I only need to open the menu and then click in the same spot 3 times rapidly in a row and voilla, back in combat
(load game, select slot, attack)You cannot kill faster manually
