Reforge it for the stats.

Short answer: reforge

Long answer: (the bold part is probably what you are missing)
character -->
ninja tool page -->
click on a tool (that you wish to "put" the stat of the essence on) -->
click "ninja tools" *on on the left side (the one next to five natures, where you usually use to upgrade tool level)
click "reforge ninja tools" sub-tab on the top (it's right under "character" actually)
slot essence to the right side of two box
Select the stat you wish to replace on the left (include empty stats) and the right(only one)
fill the bottom as much as you can to increase success
click reforge


do note that reforge might not be unlocked at the level the rest of the ninja tool system is, so the *on might not be there. I'm not sure since I was high enough level when it was released.

K what i thought just wanted to be sure befor i wasted them

I really wish Nin Tools still drop gold stats

they still do, just that the chance to get them are very very low (as they are in akatsuki, for example).

Unfortunately even they do, the stats are *. (This is based on TI Brothers Hard) Those Rare essence almost gives better stats at the moment now.

Given how rare red gourd is, this isn't strictly true.
I've been collecting the highest crit/atk/nin since 2.0 came out, and I only ever had 4 of them above 75, 2 of which I gave up so I c*e the atk/nin on it instead(I really dont like how you can only pick one...) So if nothing else, the 75 crit essence(which have a bug....) is fairly good.
I do have 10 >=60 nin, but I am also a bit short on atk, only 7 of those.

So while it IS below the maximal stat you can get on gold tools and more so compared to red gourd, they aren't *, sub-optimal but not *.

The * was referring to the current Red Gourds since last Thurs, it wasn't referring to the newly released Rare essence.

And I think you agree about the current Red Gourd being pretty bad based on your post here.

Ah yes, the current tool stat are indeed *, I've yet to see an attack value over 50... I plan to compile some data to disprove some notions too.... this will be "fun"

Even the "gold" stats on these new Red Gourds are so bad. :funk:
