Tinker's weapons/tools still taking durability with flux capacitors?

[Tyrindor]

Never experienced this before, is it some expert config on FTB Infinity??

It seems like ~5% or so of the damage goes to the weapon and the rest goes to the flux capacitor. I just had to repair my enderium tools, which was pretty costly. They never lost their charge.

When you die, the tools take durability damage (If i recall).

Well that would explain it. I'm dying a lot of expert mode because I can't just rush to OP armor. I'm also playing on hard difficulty.
