Go to the oracle is the name given to five missions in Jak II. Jak could visit the oracle in the Water Slums at its hut, after the mission "Find pumping station valve". The oracle sensed a "dark rage" burning within Jak, seemly being aware of his new Dark Jak alter-ego. He offered to help him gain control over his powers, but requested skull gems as a sign of slain metal heads, the enemy of the Precursors. In total, the oracle gave Jak control over four powers, all while talking of cryptic messages related to a young Jak, Metal Kor and the time travel behind the plot of the series.
