I think this map is best played in legacy, but I'm not sure.

You start with 5 gems faces, but they are guarded by two lvl 5 fairies. Thanfully, a neutral surprise waits right next to them so it's not an issue. After that, it's a standard level with the OP rooms except scavenger (and graveyard, but this one can be captured in a neutral area).

Soon after the beginning of the map, a hero party spawned but targeted blue as he was far stronger than me. That party couldn't find its way to the blue Keeper because tunnellers have brain necrosis, so the party went on a journey and freed a lot of heroes in the main fortress. I have no idea what happened next, but Green got killed by either the heroes or Yellow, and Blue soon followed with just Yellow left alive with his 22 creatures to my 19.

Except I could abuse the OP rooms. When the party finally went around and attacked me, a big army of heroes including many Samurais and even an Avatar followed. That was the hard part of the map, after that it got stupid pretty quickly. The main hero fortress contains many Samurais and Avatars, so my army got stupidly strong. And if that's not enough, you can find a multiply creatures special behind the fortress with two more Avatars guarding it.

I ended up with 200+ creatures and 12 Avatars because it's funny. However, I decided to reload to give Yellow a chance and attacked him with an Electric Church Squad of 6 Knights and 20 Monks. Yellow had no chance at all.

2/5, it's a broken mess but it's funny. However, there are way too many specials and, more importantly, a batshit number of traps placed randomly. So many I decided to ignore the rest of the fortress and rush the Heart to get rid of them all. Except no, because some white traps are placed on dirt tiles. Also many, many gems. 2/5 difficulty just for the big hero fight.

EDIT: I looked at the map in the editor. It has no party spawn, in fact it doesn't use action points or triggers except basic settings. The tunneller is here right from the start. Also, no wonder Green got destroyed.

A map like all the others. To win destroy the hero heart and what is left of 3 rival keepers(they kill each other). You have loads of gems and can research temple, prison and torture room from the start. There are a lot of high level heroes on the map, including several avatars, but if you just keep imprisonment on, no matter what you do you'll win. You do need to keep making imps though, there are so many traps. Tiny issue with some of the traps on the east side destroying the heroes instead of your imps, but I can live with that.
