Affably Evil Walkthrough
This is a walkthrough for Affably Evil, by Dugi. It was created using BfW 1.14.15, AE 1.0.0h and Legend of the Invincibles (LotI) 3.2.7. This walkthrough was created by White Haired Uncle (WHU). I am assuming the reader is familiar with LotI's unique characteristics, if not it is highly recommended to at least play the tutorial at the beginning of LotI Part I. Note that AE varies slightly from LotI in that only certain units can pick up items (even gems) and there are no recalls other than the special units that are automatically recalled.
Incarcerate
[WHU] This one is quite hard. There also seems to be a lot of luck involved in the gear you are provided with initially. The enemy has a lot more income than you do, leading to a steady stream of attackers with really no time to heal. And your leaders pretty much suck. The idea here is to incarcerate as many of the enemy as possible. When an enemy unit, anywhere on the map, has 4 or less HP, you can right click on it and incarcerate it, eliminating the enemy unit and giving you 10 gold. I'm sure the idea is that this will make up for your disadvantages, but in practice it really doesn't. You'll see a lot of enemies with 5, 6, or 7 HP, but not a lot that you can actually incarcerate. Still, you should try to incarcerate, which often means choosing to attack an enemy with a unit/attack that won't quite kill if it gets N hits. And always scan the battlefield completely.
[WHU] The only way I've found to win this scenario is to give the swordsman (Judas, the only really worthwhile unit at this point) all the gear I can, then send him after the southern leader along with the white mage (Antipater) and some support/fodder. Meanwhile, Krux recruits a steady stream of units to protect the allied leader (not an objective, but you need him for his income to recruit). Killing the southern leader, who has a high income, will remove much of the pressure in the center of the map from his constant recruiting, turning the tide just enough. At this point, Judas and Antipater probably need to make a hasty retreat from the enemies coming in from the west. Assault the central leader, probably using his castle to recruit another wave of bodies (remember, the leader in the west is still recruiting too), and then charge west. The river seems useful, but you don't have the turns to spend much time there, better to charge right past his advancing army and go for the kill.
Libreborough
[WHU] You will be offered an ally. Take it, of course, allies are the only units that really count in this campaign. Check out the obelisk and learn how it works. Gear up your units as best you can. If/when you can, I like at lease one Wretched Defiler melee weapon to score some fodder that the AI seems obsessed with. Head northease, encounter a few bandits, and proceed to Menacing Hills.
Menacing Hills
[WHU] Slowly work your way to the northeast corner. As you progress, you'll trigger small packs of bandits, so keep your army together. There's no turn limit, so there's no reason to use all of your movement points in a turn, save some in case you want to retreat/regroup.
Strych
[WHU] Visit the traders and buy some items if you like. Enter the building to trigger a talk with the parents. Choose your legacy. Exit the map to the south.
Southern Estates
[WHU] Go south to make contact with the waypoint (always contact the waypoint the first time you visit a map). Move west, triggering some enemies. Retreat to the villages and defeat the enemies. Follow the path through the swamp. At night, walking dead will appear, so watch the clock and make sure you keep a good formation on advantageous terrain.
Marilyn
[WHU] Kinda tricky, as it's easy to get lured into the obvious fight at the river initially. Send a couple cavalrymen, one clockwise, one counterclockwise, around the map, collecting villages. Defend against the first wave. When the cavalryman in the east crosses the river, it will trigger a talk with Marilyn. Pull all your units back north until Krux has an idea.
[WHU] Marilyn has a lot of income, and can pretty easily overwhelm you. Send a handful of cavalrymen counterclockwise to steal his villages, assist the undead, and just generally distract him. This will also give you more visibility to use incarcerate. Fight off the second wave, recruit heavily, and head down to the (new) castle at the river. A fair fight here is a losing one, so send those cavalrymen in on a suicide mission, taking the villages near his castle so his forces will be distracted and you can make it across the river. Once you get across the river, you may need to go around his forces instead of through.
