King's Bounty: Armored Princess

I'm playing as Paladin on Hard difficulty.
I had very bad luck with random encounters. Basically, the coolest unit before Verona was 3 units of Core Thornlings. I was using archers, imps, Core Serpents (plus Serpent Boots!), and Inquisitors. Then, using a Scroll of Raise Dead, I raised 49 vampires (I think it was on Crimson Wind).
Verona was the 5th island in order. At the entrance, you could buy Demonologists.
This annoyed me, so I sailed to the Elves, stole the Scroll of the Isle of the Nameless from under their noses, sailed there... bought vampires and 4 Black Dragons there...(I didn't touch anyone on either island). I returned to Verona... and the fun began. I cleared everything except the capital, where Demonion had entrenched himself. I went to Montero, where I defeated everyone except the Driller. At the entrance to Montero, if you sail through the air on a wooden square made of planks... you can reach the Dragon Cave... you have to defeat them - it was a fun battle - a level 29 hero, took meat and 4 Black Dragons against 18 Black Dragons, 22 Red Dragons, 40 Green Dragons, and 800 Lake Dragons... after the battle, only 4 of my Black Dragons remained (plus one squad was resurrected 100%). But then I could hire all 3 types of dragons, which I did. And that's how I've been playing ever since - Black Dragons, Red Dragons, Emerald Dragons, Inquisitors, and Vampires.
Somewhere on the Orc island, from a chest that a little dragon created on the battlefield, I found a Scroll of Sacrifice... so I started breeding vampires and Inquisitors every time I increased my leadership.
I defeated the Spider on level 32, and not quickly, and the Toad on level 37 (both without losses).
I defeated Cthahu on the 7th at 8:00 PM (level 46)... before the battle, you need to dig up a dagger that gives +20% damage to Cthahu and 15% to all lizards :)

I got wings for the hero on level 30.

I just sailed to the Isle of the Nameless - it's the 8th day, 1:00 AM.
I also have 210 battles without losses!

P.S. - I keep Inquisitors - to increase rage. I periodically cast Phantom on the Inquisitors, 2-3 squads massively increase rage. Plus - if they kill several dragons (Red or Green), I heal a dragon to almost 60-90% health, and then the Inquisitor phantoms resurrect them :)

I agree that your Core Griffins and Pladins are super units!!!

Did you build your army for Cthahu specifically, or do you always use this kind of army?

I initially took 5 squads, but I see that Cthahu is systematically killing them... I thought, is it worth it to have so many losses? That's why I only took 2 squads. I gave Stone Skin to the Vampires, and also Stone Skin and Armor of God to the Emerald Dragon, and sometimes I healed him too. The Vampire stood in the center - distracting everyone, and the dragon attacked in melee every round on the injured side, then he doesn't retaliate!
