Trouble with items

[Neogame2]

Hi I just started playing GC PSO in europe, I've found a photon drop and an amplifier of Gribarta, can any1 tell me what they done or are for?

photon drops you have to take online and trade with some guy for items, and amplifiers have to go with the barrier of its color like BLUE BARRIER would go with amplifier of gibarta, they make your spells do more damage
