Walkthroughs for custom maps.

In the second-to-last mission, you need to be careful so that the last one doesn't turn into a months-long ordeal with accumulating dozens of skeletons.

And in what way should caution be exercised? In the last mission, before the keymasters' tents, there's an antimagic barrier guarded by 7,000 gold dragons (a thousand in each stack). Troops from the previous mission don't carry over, and I don't see any way to obtain flight or a portal in this or previous missions. This guard doesn't use any tricks; that is, it will have to be broken through with brute force, specifically with tens of thousands of skeletons, yes. Or with a vampire archer. What other option is possible?
