The durability of Tinkerers Tools has to be a certain percentage of the stored RF in the flux capacitor. The formula is Maximum stored RF/1000= minimum tool durability.To use a Redstone Flux capacitor, you need a sword( or any other tool) to have a base durability of 2000+.Why can not I add "redstone flux capacitor" at my broadward? I've 4 modifier slot but i can't add :s
Sorry for bad english
Redstone Flux Capacitor=2,000,000 RF/1000 =2000 Minimum durability on tool
Hardened Flux Capacitor=400,000/1000 = 400 Minimum durability
