Palladium is a rare ore that is only used to exchange at a ratio of 15:1 for extra energy, used in the Galaxy Gate Generator. It can only be found and collected in two of the three Pirate maps 5-1 and 5-3, while only being able to be exchanged in the base of 5-2. Once a player has collected more than 15 Palladium, you are then able to exchange it. It cannot be exchanged for anything other than extra energy. On map 5-1, there is Palladium in the very center of the map. But there is a small quantity, so it is not recommended to collect the Palladium there. In 5-3, there is a large area at the bottom of the map, sutiable for collecting large amounts of Palladium.
15 Palladium = 1 extra energy
Palladium is a highly valuable ore for anyone looking to build a Galaxy Gate; to get it, many players employ a cloaking device and send a P.E.T. 10 with the Auto Resource Collecter gear to retrieve it for them. Entering the Mist in 5-3 will uncloak a ship. It no longer drains your shield by 200. Collection time of Palladium is about the same as collecting Terbium. If you own a PET, I recommend using it to pick it up for you since it is a tedious task.
If you have the P.E.T 10 with level 3 Auto Resource Collector it is advised to sit just on the border of the blue mist and let you pet collect the palladium, meaning you remain cloaked. This is unadvisable if you want a large quantatity of palladium quickly, however is useful when you don't have enough to repair your ship/drones if you die.
Palladium is an official element of the Periodic Table that is non-radioactive. It is element number 46, with an atomic weight of 106.42 and a density of 12.023 (obviously more dense than water.)
