What it does: You can repair damaged Dalek casings and get in them by right clicking them with dalekanium. This allows you to operate the casing, fly / glide and fire the gun. This also makes you undetectable to other Daleks.
How it benefits: This gives a use for dalekanium outside of armour and weapons. It also makes a nice decoration item.
Why it would be cool: You can A: prank your mates. B: have some decoration for Dalek-based builds.
