YES! I finally did it even if it drove me nearly crazy doing it. I realised that against Baal you have to attack and quickly. So I put away the Inquisitors and went for a team of Paladins, Knights, Horsemen, Inquisitors and Guardsmen. I had the Knight set (20% more leadership), Flaming Eyes and the Inquisitor sword, which meant I had something like 334 Paladins. I needed every one of them though.
The strategy was to allow Gilbert to cast Mass Haste and then use Stone Skin myself every turn. I made sure to have a line of two troops in front of Baal at the end of each turn to encourage him to hit me. That flying sword is a killer so you want to avoid it if you can. I took him down in about 12 turns by just repeatedly whacking him with the Knights, Paladins and Guardsmen. Mostly the Horsemen were for mopping up spawned enemies. If Baal takes a certain percentage of his damage, he will do the attack that destroys part of the ledge, but no matter.
The trick I was trying to pull off (and it took about four tries to get it right) was to almost kill him and then allow him to spawn some stuff before finishing him off. I used Blind at first to try to complete my resurrections, but I kept running out of time and mana, and it was a pain. Then I realised that if I left a stack of Scoffer Imps, I'd be able to do it as Scoffers have 3 rounds of special attacks (2 x Fireball and 1 x Enrage) and THEN they have no retaliation. Perfect. So I used Calm Rage to get more Mana and kept pumping out the Phantomed Paladins every turn. Probably took about six turns of this until I was back up to full stacks.
Then, after all of this, the sweetest of victories!
