his is one of Jak's first Eco Power that he gets before attacking the uber bot. It is a Green Eco Power that allows Jak to create crystal spikes out of the ground or walls several feet away. If it is used during an enemy's melee attack, it will freeze the enemy in place for a few seconds. Also there are certain places that have patches of green crystals where Jak can use his Construct power to create temporary columns or platforms to help him cross a chasm or other navigational obstacles. Jak has to cross these platforms quickly before they collapse.
