there is one rare in normal that is worth finding. redria, normal vr temple, nar lilly, 87.5% addslot. i used that to find four and use them on my spirit garment (which will eventually become a brightness circle, or aura field)
I though that the only rares in normal were photon drop and addslot. Correct me if i'm wrong.
you can also get a bunch of the bad special weapons, like broniac, and booma's claw. they all have absurd drop rates, though.
In most cases they're not really worth it.
Goos choise but if you wanted more technique power you better use a Fonewearl, the problem of the newmans is the HP, but if you know how to use Restas, mates and to escape from attack it will be much better
On topic, you plums! Orphen, you should be ashamed, hahahah!
