High combat level: Focus on killing players in the important areas (Graveyard and obelisk) and, when you are able to, the opposite team's avatar. If your team begins to lose the lead you should begin collecting soul fragments and weakening the opposing team's avatar. Low combat level, 30+ slayer: Focus on killing the Pyrefiends and Jellies that surround the main part of the map. Collect the soul fragments that they drop and deposit them at the Soul obelisk in the center of the map. (Note: This can only be done if your team has control of the obelisk)
