Im currently on an item hunt to obtain every item in the game but there are items that are eluding me like the nil set.Is there an easy way to get them without item modding?

I'm not sure what it is, but none of the items in the game are that hard to get...

Either just do all of the quests because many rare items come from that, or look in other Guild Shops. Almost all of the 'rare' items in the game can be retrieved by simply doing the quest, though...

Im speaking of the nil items such as nil strike, nil theft ect. I want them for an experimental wepon im creating.

I don't know about them. Maybe you should do the quests. I didn't get those from the Chim Quest or the Mecha Grunty Quest. Maybe you get those from the others?

I've never heard of them at all before...

Found 'em:

Nil Strike - Block 56-59 reward FoP (Defeat 7 Enemy Parties)
Nil Theft - Block 61-64 reward FoP (Defeat 7 Enemy Parties)
Nil Madness - Block 66-69 reward FoP (Defeat 7 Enemy Parties)
Nil Defile - Block 71-74 reward FoP (Defeat 8 Enemy Parties)
Nil Ally - Block 76-79 reward FoP (Defeat 8 Enemy Parties)
Nil Charm - Block 81-84 reward FoP (Defeat 8 Enemy Parties)
Nil Encroach - Block 86-89 reward FoP (Defeat 9 Enemy Parties)
Nil Abduct - Block 91-94 reward FoP (Defeat 9 Enemy Parties)
Nil Embrace - Block 96-99 reward FoP (Defeat 9 Enemy Parties)

What do they do?

No idea. I only found out HOW to get them. Not what they do.

Thank you atoli chan.

Your welcome.

The Nil items I believe can be equipped to weapons and add benefits. The difference between these items and others are they tend to take up one or two slots instead of three like certain other material. They're great items, but at that point of the game when you get them, they're not that needed.

But what do they do? I only have Nil Strike, Nil Madness, Nil Charm, and Nil Embrace. But... I forgot what I did with them.

The same thing as weapon materials or armor materials, they just take up less room Slot wise.

Well, I'm currently doing a FoP run again, to get all the items I missed and I'm up to 70 now. (And Athrun, Yata knows Lapu Do which is better than Ap Do.)

Nil Strike - Critical Increases By 25%
Nil Theft - ???? (I need to look at it again.)
Nil Madness - Adds Confusion to Attacks

Those I got so far.

Are they all 1 slot required?

And I already mentioned Yata's awesomeness... Total Buffer and Healer at the same time.

So far, yes.
