An item (or would it be considered a set of items?) Skyfire would like to get his tool box (plus tools) back. He can live without the stuff that was nerfed, but he'll really want his tools when he eventually gets hurt. They're in a rough carved wooden box and there are about 20 of them in total.

They don't really have powers, it just took him a long time to make them and it's very hard for him to do anything with fine precision without them. Like repairs, writing, tinkering...
