Ever tried godswording? It might sound crazy, but with slayer mask, karil's top, verac's skirt, and the usual stuff, you can get 20 kills a trip with a tortoise pietying, in around 15 minutes. Be sure to take an antifire pot and antidragon shield to wear when looting or when you are not in range of their melee attack. 1 super set and antifire, drink every 5 minutes, 4 prayer pots to turn piety on/off, and rest food.
