crystal spikes

The crystal spikes were a pair of climbing tools that served as Nuju's Toa tools when he was a Toa Metru.^{1, 2, 3, 4, 5, 6, 7, 8} Nuju used them to channel his elemental power of ice.³ They were lined with spikes and could grab onto sheer surfaces, such as the sides of Knowledge Towers.³ Nuju could use them for climbing towers or swinging from tower to tower.^{1, 2, 7} The crystal spikes could also be attached to Nuju's feet like traction cleats.⁹

Nuju selected these tools from a compartment in the Toa Suva when he first became a Toa.^{10, 11} When Nuju was mutated into a Toa Hordika, the crystal spikes mutated into Hordika teeth. When Keetongu cured him, the crystal spikes returned to their original form.^CN They transformed into Nuju's Ice Pick when he became a Turaga.^{12, 13, 14}
