Walkthroughs for custom maps.

Sounds plausible. We hide behind the Castle, summoning a boat for it beforehand, and wait for it to sail away. Then we take the Castle, buy 7 heroes, and block the landing with burrows or heroes. Then, when it reveals the entire map, we put 1 hero in the boat and make sure the AI kills it by getting as close as possible to the shore. Then we use a hit-and-run tactic with an explosion :)

I looked at this option right away, but the condition was 1-2 days, so I discarded it. Instead of heroes, you can dig pits, taking advantage of the excavation bug. There was also the option of letting it learn Teleportation so it could fly to the Rampart)))

I tried buying Jemma myself, but for some reason, she arrives without a tent, and the ballista specialists arrive without a ballista :confused:

This is an isolated case. The tent is like a second level of troops: the hero may come with it, or may not. When purchasing, all heroes "sort of" arrive with three stacks, even if it's just one - this can be seen by the number of starting moves. It takes several attempts.
