Traverse the ice field, Bring Moonstones to Mystic, and Trade moonstones for Hypnomatic Part are missions in Going Commando, taking place in the Tundor Wastes on planet Grelbin. When Angela Cross invited Ratchet and Clank to meet her at her home, they decided to explore the ice field near their landing spot. In doing so, they found the Mystic, who claimed to be capable of lifting a rock blocking the way inside the ice cave if he was given nine moonstones, to which Ratchet and Clank obliged.
Walkthrough[]
Traverse the ice field[]
No new weapons are available at the Megacorp vendor, but the enemies fought here are extremely powerful. It is a good idea to purchase the Shield Charger if you have not already, and your weapons of choice should be the Plasma Coil, Bouncer, Hoverbomb Gun, and Minirocket Tube; use this as an opportunity to upgrade any that have not already been upgraded, but keep in mind once upgraded, these weapons will be good choices for farming moonstones nonetheless.
Your main enemies are the Y.E.T.I.s and the arctic leviathans. The Y.E.T.I.s are melee enemies that attack in large numbers, while the arctic leviathans are ranged enemies that are found beneath ice pits and will breathe blasts of ice. They usually guard moonstones. Both enemies are very durable and can easily overwhelm you if being careless.
"Traverse the ice field" is completed upon talking the Mystic, who you can find by taking the slope down to meet him by the rock at the entrance to the cave.
Bring Moonstones to Mystic[]
After a short cutscene, head out into the ice field and obtain moonstones either by breaking them from their blue ice shells, or by defeating arctic leviathans. You can obtain a total of fourteen right now, five from defeating arctic leviathans, and nine from the shells.
Once you have nine (or all fourteen), return to the Mystic to have him clear the path into the caves. He will then offer you a Hypnomatic part in exchange for sixteen moonstones in the mission "Trade moonstones for Hypnomatic Part", though you cannot obtain sixteen until after you complete "Explore the caves".
Trade moonstones for Hypnomatic Part[]
As you can only obtain five more moonstones on the lower portion of the ice field, you need to create a bridge up to the upper portion, which can be done by completing the mission "Explore the caves". After this, you need to obtain a minimum of eleven more moonstones on the upper portion to gain a total of sixteen. Due to the enemies' durability, you will run out of ammo very quickly. It is often faster to simply drop into the ice pools and respawn to get back to the Megacorp vendor and restock on ammo than to use the Charge Boots all the way back.
Once you have obtained enough moonstones, return to the Mystic for the Hypnomatic part. At this stage, you cannot complete the mission "Find Angela" until you obtain the full Hypnomatic from the mission "Bring Hypnomatic parts to Hypnotist" on Damosel. Consider finding more moonstones for 3,000 bolts each, but you do not need to find them all at once; obtaining the Mapper from the mission "Explore the moon" on Damosel will make the process significantly easier.
