Caches: Carrying on the attributes from map to map

I can't seem to find any tutorials or anything about moving items and hero levels from map to map in a campaign. Anybody know anything?

Game Caches are what you're looking for.

The first thing you need to do is create your game cache, using the triggered action 'Game Cache - Create Game Cache'. Pick an original name for the file, one not likely to be repeated.

Now it's simply a matter of storing the information you need. Store Unit is the command you're looking for--you'll want to store your hero at the end of the level, as well as Saving the cache. Then it's simply a matter of restoring said unit in your next map. Note that custom heroes and items do NOT work with game caches. If you wish to have a hero while maintaining the original ones of that hero's race (IE, you want to make a Mountain King hero while keeping the Mountain King himself free), you'll have to modify one of the Special heroes. The same goes for items--fortunately, there are plenty of unused items in the game, so it's not such a big deal.

Remember though, this won't work in multiplayer games.
