Walkthroughs for custom maps.

I completed Paragon 2.0 in seven game days.

1) After defeating Olvin and gaining access to the red portal, we can free Wael. He has the best skill tree of all available heroes and has expert-level fire magic. Erionna also has it, but Wael has defense and attack instead of air and intelligence like Erionna.
2) We lead Wael to Invincible, get stats of 90 and 99 Azure Dragons. We increase the stats to 99, defeat Invincible, get another 200 dragons and the Orb of Vulnerability.
3) Behind Invincible is a portal leading to several dangerous places. First, we free Ghashru and get 1000 Hydras with her. If we're unlucky, we'll have to defeat Hydross first, as he may block the way.
4) We buy at least one Magic Dragon in Targron's domain. We defeat Heliar in the Nameless, obtaining the Cursed Armor. We go to the portal, pick up the Pandora box with 9000 Sorcerers, which was intended for the Incinerator. The battle with Heliar was still not easy; with his rage, his 8000 Sorcerers kill all the Azure Dragons at once, plus he has antimagic and sacrifice, a necklace of blindness, and all stats are also 99. In the battle with him, I had to use the infinite resurrection bug with Archangels when a Fairy Dragon is in the army for the first time; the bug is described in the Physigma version 2.7 on page 120 in the section about neutral creature abilities. Otherwise, there wasn't enough mana for a regular resurrection, and there weren't enough Archangels to use Clone. Perhaps, in the order of completing the game, this step and the next one should be swapped.

Good afternoon.
But what is the purpose of doing all this? If all the outposts have been taken, you can simply come and take the orb behind the blue gates from Peplocry. Just to increase the score?

hence the question: was it worth it? (+10 attack, minus all money). If I remember correctly, + - attack, is the map still passable? It's more difficult without money, as you can't buy strength. Or are these +10 so important for completing the game?

Good afternoon. Of course, it wasn't worth it, as these +10 attack points are no longer needed towards the end of the game. It was just "self-entertainment."
The goal was to test the strength of a situation that is impossible in the storyline, and I succeeded, almost in a fair fight (without bugs like infinite resurrection, etc.).

Experienced players, I need your advice; I'm trying to defeat Metathax.

Background: on day 212, I barely managed to take Solmyr's castle, defeat the Rust Dragons, and grab the Pandora's Box from the Elven castle (on this turn, two heroes appear: a Boss from the Elven castle with 600 Dragons and another guy with a smaller army). The question is, what are the timing points on this map that you absolutely must complete? I can open the "Sunken City" before 2.2.1 for 100,000 gold, and I'll take the tower city on the island on the same week (in the end, there will be 3 tower cities: my home city with the Grail, Solmyr's castle, and this one). On the internet (in Russian), I only found streams from Dandy, but he rushes through it as if he's on fire and replays weeks 2-3 an unreal number of times. I don't want that kind of gameplay, and what's the point of copying someone? (besides, I wouldn't be able to; my A Friend doesn't get defense on level 3, and to get the Admiral's Hat on the first week, I have to defeat the Fairy Dragons, i.e., lose 1 day...). In general, I managed to complete A Friend's quest just in time on day 126, while Dandy did it on day 124. The second question: does the map necessarily require a fast run, or can you take it easy and "ride horses around the map" at some point?
