How did you defeat the mages? Did you buy a Town Portal? Did you build an Arsenal? How do you have so much money? :)

Did you level up at the Tree of Knowledge for 2500? I did.

I know what's there. Who did you use to defeat it? Just one Vampire? Or did someone else help?

Same here - only I don't have ghosts, I took about 30 Imps and two Vampires. I also got into two boats, but on the 7th day. So, how do you plan to deal with the Harpies, or where will you sail? Does your hero have any potions? Do you have a Town Portal? How much? You seem to have enough mana. I wouldn't have been able to do it without Vampires, so I want to hear the details of the battle :)
I still don't understand how and with whom you defeated the mages. And what about magic resistance?

So, how do you do it without any problems? They poison you, after all. I just didn't take a hero into the battle.

to the opposite side. In short, it's easy. But what will you do about the Harpies without Slow? Even if you age them?

I'm answering your questions, Iron.:D

I didn't build an Arsenal, and I don't have any potions of immortality. I leveled up at the Tree of Knowledge for 2500.
I got Necromancy 3 there, and in the tower, by the beginning of the fifth day, I have 2000 gold, a Sword of Vitality, Slow, and Cure.

Now, how I defeated everyone.
I defeated the tower with one Vampire and one Ghost. The Ghost aged the Archers.
The Vampire then bit the fastest unit and passed the potions from the Vampire to Solmyr.
And then, in a chain, to Sandor.

Sandor fought in only a few battles, more precisely, four.
He simply lured the Gnomes and used them to raise the first seven Ghosts. Then...
He attacked the Tigers with two Ghosts. One gave Aura, aging the Tigers, and the second simply aged the Leprechauns. Then he poisoned them all and ran around until they all died (when attacking, I positioned the Ghosts so that the Tigers and Leprechauns wouldn't split into three groups).
Minotaurs and Medusas: he also attacked with one Ghost. The Ghost aged the Minotaurs.
He cast Haste on Sandor and poisoned the Medusas with a counterattack, after which they simply followed him along with the Minotaurs until they died. The same thing happened with the Minotaurs.

Finally, the most difficult battle against the Mages and Halflings. Sandor attacked them.
He takes six Imps with him. The Imps are positioned so that they go first. The Mages split into two groups, and the Halflings into one. In the first turn, the Imps drain 12 mana from one group of Mages out of 16, leaving 4 mana in the group. Sandor casts Mana Drain on the second group. Then the Mages attack. The un-drained group poisons Sandor, and the rest simply attack the Imps. In the second turn, the remaining Imps drain the remaining mana from the Mages. Sandor is, of course, poisoned, but not yet dead. In general, when the Imps have completely drained the mana from the Mages, Sandor drinks a Potion of Healing and is cured of the poison. Then he poisons them all, casts Haste on himself, and simply stands on guard until the Mages die and the Halflings run out of arrows. Then he runs around and wins! After the battle, Sandor has 5 hit points and 30 mana, and 17 movement points left, but he naturally gets into a boat.:cool:

Now, about the Harpies, I haven't reached them yet, but I have a Potion of Slow, and I'll probably still build a Forge. I need acid, and a Potion of Strength with Slow would also be useful.
I haven't reached the Gargoyles yet either. I'll check it out today and write to you later.
Okay, I'm going to play.:)
