I am glad when I find my catalysators for Lightning's Omega Weapon (or whatever the translation is called) and all the equipment.

Here I warn people who haven't noticed some of my posts:

Do not sell your equipment in case you have just 1 item of it. You can get them later and buy them later but when you sell all your elemental rings (they appear more than just once) and you haven't upgraded them (1 of fire, 1 of bolt, et cetera) it is almost impossible to get the golden equipment trophy. It can even be impossible. This trophy is one of the only trophies I haven't yet. And you need time for it.
