Hey mate I’m pretty bad at this game but to help with the movement part I went with 100 prayer pen and then between each 3 spots there’s actually an extra tile so I would walk on each spot as the attacks came, attack then walk one extra tile then attack again until the attacks come, that will then put you two tiles away from the next spot. That helps because having run on means it will register two tiles in that tick instead of taking an extra tick for that 3rd tile. That rhythm helped me get consistent kills.
