Finally, I got my hands on the demo, and I immediately jumped into a duel. I played two battles as the Dungeon faction, the first against the Academy and the second against the Haven.
I won both, and I can share my tactical formations. So:
Against the Academy, we combine everyone we have, resulting in 4 stacks: 15 Matriarchs (placed in a corner), 26 Witches (in another corner), 220 Furies (in the center, in the second row), and 62 Raiders (placed away from the Witches, in case Jora casts a spell before the Raiders' turn).
The Furies' first turn: attack the Djinns (20 remaining, reduced to 2).
Next, my Raiders move (after the Djinns are defeated, having taken out 4 Furies): they attack the Rakshasa (out of 10, 5 are defeated; they have tough skin).
Then, my Matriarchs are hit by Chain Lightning (3 are defeated, along with 9 Furies).
It's the Matriarchs' turn: Confusion is cast on the mages.
Eruina casts Meteor in the corner where the Archmages, Golems, and Goblins are located (340 damage to the ranged units, 150 to the Golems). The 26 Witches simultaneously eliminate another 11 Archmages.
The Witches fire at the Archmages (another 12 are defeated, leaving 26 out of 60).
The Archmages fire at my Raiders, and Confusion only defeats three of them.
My agile Furies move ahead in the turn order and attack the Rakshasa (they are next to my Raiders; I use Lizard Byte): another 4 are defeated.
His Golems, Gargoyles, and Goblins damage my Raiders, leaving 19, but the Golems move away from the ranged units, allowing me to attack the Archmages with the Raiders (15 are defeated) and block the Goblins.
From here, it's just a cleanup, as Gargoyles and Golems are not effective against Furies. The Raiders hold out for 2 more turns against the Golems and Goblins, using Defense. The Furies eliminate 160 Gargoyles in that time. The Witches and Matriarchs shoot down the Goblins. Two more "cannon fodder" units are lost, resulting in 19 Furies and 6 Matriarchs lost. However, the Meteors finish off the mages and Goblins.
In the end, my Ladies happily finish off the Golems.
In the end, there are 26 Witches, 6 Matriarchs, and 189 Furies remaining.
Against the Haven, we combine the Furies, Raiders, and Witches, and split the Matriarchs into 4 stacks (4+4+4+3).
The Furies attack the Griffons (out of 40, 33 are defeated), after which he has the opportunity to use the remaining 7 for Battle Dive.
The Raiders attack the Paladins from the flank (out of 20, 15 are defeated; Lizard Charge is just great; it completely negates his huge knightly defense).
One of my Matriarchs manages to move before the Archangels and casts Confusion on the Marksmen.
6 Archangels attack my Raiders (by the way, I don't understand if the Paladins have an ability that allows them to attack simultaneously; my Raiders killed 15, but they took damage as if from 20, resulting in 28 casualties). Another 11 Raiders are lost, but next, my wonderful Eruina steps in and casts Meteor on the Archangels, Paladins, and Swordsmen, defeating 2 Archangels (almost defeating another), 4 Paladins, and 14 Swordsmen.
The Furies eliminate 3 Archangels in their second turn.
7 Griffons from Battle Dive land on my Witches, but they don't take down a single one.
The remaining 3 stacks of Matriarchs defeat the Griffons and cast Confusion on the Inquisitors.
His hero runs across the field and defeats one Matriarch.
My Witches fire at the Marksmen, dealing 50 damage.
His Swordsmen run forward towards my Furies, and the Inquisitors and Marksmen almost finish off the Raiders (3 remaining).
Eruina casts a second Meteor on the Marksmen and Inquisitors.
The Furies attack the advancing Swordsmen and defeat more than half of the stack.
His last Archangel revives 10 Marksmen, and the Paladin is defeated by the Furies.
My Matriarchs (all 4 stacks) "nullify" the Inquisitors' defense, after which the 26 Witches defeat 8 of the remaining 11.
Eruina finishes off the Inquisitors and Marksmen with Meteor.
The Swordsmen finish off the last 3 Raiders, and his hero defeats another Matriarch.
The Furies finish off the last Swordsmen, and the Matriarchs and Witches defeat the last Archangel.
In the end, 13 Matriarchs, 26 Witches, and 175 Furies survive.
I had a lot of fun with the graphics and my favorite faction. Thank you, dear developers
