Where to do it

| Ancient Cavern | 16 | Safespot · Quickly accessible with a games necklace to Barbarian Assault Because the waterfiend attack range is only 4 tiles, it is possible to safespot them by attacking across the river using Ranged or Magic or waiting out the aggression timer on the western side of the river and using the stalagmite across the river to the north-west. It is possible to wait out the 10 min aggression timer by following these steps: Running all the way to the safe spot by the pillar (see image below). Running back up the stairs to the platform you land on when you jump into the whirlpool and waiting out the agression timer there. Running back to the safespot. |
