Yesterday, I managed to defeat the Red player, reaching 336 points. I cleared out all the Gnolls in the first garrison, so after that, I was mostly fighting Wyverns :( I lost about 15 of them, if not more, to lightning attacks. The battles with Chuassec were quite challenging, with three very tense encounters. And with Chipheska, there was only one almost bloodless battle (she repeatedly tried to cast Expert Slow), but the real problem with her was catching her when she fled to the Barbarian respawn point and was left without castles. She had the key ring for the scenario with her (Tazar constantly ran past it with his snakes but never picked it up), and a useful shield as well.

The Red player built not just Hydras, but Chaos Hydras :)

I think we can leave the Hydras and Horrors for the secondary hero, who will sit in ambush with the Imps. Ideally, after the first defeat, the Inferno player will be hesitant to leave their castles and will constantly buy them out if someone is stationed there.

I'm still feeling guilty about sacrificing the Captain's Hat at the altar. It gives 60 Wyverns. But I doubt that without those 6k experience points, I can have a good start on this map.
