Done Tinker construct Flux tool Problem

Hello
I want make cobalt pickaxe with flux modifier on but i can not place any thing to add flux modifier on. i try lead capacitor, hardened capacitor, lead energy cell, hardened energy cell and nothing work, i try in solo and the hardened flux capacitor work so my question the flux modifier is its banned on server ? (i'm on node 3 infinity)

 

do you got a spare modifier to give your tool flux?

 

They made it where the amount of durability is the teir/level of flux capacitor. Maybe add more durability?

 

The durability of the tool has to be 0,1% of the capaciptors max charge.
400 for Hardened Capacitor
2,000 for Redstone Capacitor
10,000 for Resonant Capacitor

And, of cause, 1 free modifier

 

ok thx and yes i have 5 free slot of modifier i will try and add diamand and after capacitor thx guys
