3 levels with restricted units, then 7 levels of werewolf rushing. When I say "lord werewolf" the intention is to make werewolf building 3 at very end of level and choose the level 1 as the Lord.

New Subjects of the king

Goblin regeneration spell for tanking, rats for damage. Spearmen flee in terror less often.

Sliver of immortality

Timer mission. Destroy 5 portals north of base early. Expect groups of 9 heros attacking day 30 - they can go on either your base or direct on lich guild. You have better army quality but poor AI. Let them walk in, then attack flag them closest to furthest for consistent result.

Power of minotaurs

1 goblin for Regen spell 1 ratman for explore, then get 2 lich guilds. To destroy ancient guard towers make sure to use inn to group into 2 parties first.

Chosen by the plague

Get 2 werewolves and go. Ignore humans.

Dwarven gratitude

First boss. 2 werewolves + lord werewolf+ 2 koatl.

Elves and dragons

1 werewolf can kill elf village. I like 2 werwolf + 2 koatl for temple of Helia.

Gift of lunord

2 werewolves+ 2 lord werewolf. Lich guild to spell kill repair peasant.

Mystic tavern

Semi timed. Killing tavern early needs testing (minimum strength to survive level 40 heroes uncertain)

Ritual of death

This level crashes a lot for me so it's difficult to plan. Mix wizard tower cheese with werewolves.

For crown and honor

Building temples is forced. Temple archers have highest damage. Get 2 temple healers and 6 temple archers(highest damage) remember monster temple heroes need to learn skills at guilds unlike humans
