Shields shouldn't be able to have those enchantments, and I doubt they even work. I've seen the same issue with Electric Treetap, and it probably affects other tools too.

I'm using IC2Classic-1.12-1.5.8.jar and 1.12.2-forge-14.23.5.2859.jar.

@dwentz89 just checked it.
This is only possible while you are in creative mode.
Where minecraft disables all "Validity checks".

This is not an IC2C bug.

Ok, so it doesn't happen with the Anvil. I posted bad reproduction steps, and I'm sorry about that.

This does happen with the Electric Enchanter though, even in Survival mode, so there is still an IC2C bug.

@dwentz89 yeah ok that is a good example.
Good that i didn't finish the update yesterday.
I will patch it today and depending how long i wait on responses on other issues it will either release tonight or tomorrow.

Ty.
