In the minigame, players try to capture the soul obelisk. Once the obelisk is captured, players may use the Soul fragments on the obelisk in order to lower the enemy avatar's Slayer level. In the quest Nomad's Requiem, it is confirmed that Nomad created the soul obelisk and all soul shards used on it are transferred to his 'throne' which siphons their power into him, causing him to gain tremendous power.
