Beat pillar ring challenges was a mission in Jak 3. Both Samos Hagai and Keira Hagai have discovered that the Precursor pillars at the Southern Haven Forest are related to the Precursor artifacts Jak found. Jak must travel to the forest to uncover the pillar's secrets.
Another JET-Board mission in the forest area. This time you have to chase a light trail through several rings in a race against time. There are five Precursor statues resembling oracles here that unlock one after the other. Walk up to the first one and smash its nice to begin the first challenge. You have between five to ten seconds to get to the next ring, when you get the last one the statue will explode and you can move to the next one.
