Stage 10, named after John Van Caningham.

Heh, logistics are really tough. Without it, I definitely wouldn't have reached level 35, because I ran the last five trees in the last four days, starting from day 24.
For the third time in a row, I'm right up there with Wolf in the final standings. Although we had completely different builds. It's almost mystical. :)

Here's my Walkthrough.

As always, at the beginning, the question of character development arose. So, Sinistar. Naturally, I really want to get the Logistics and Education skills, and at the start, there's Chaos available – leaving two free skill slots. It would be nice to get a summoning skill (in the Guild, you can learn Phoenix Summoning, and in Sanctuary – Regeneration, and then you'll also get Wall of Swords) and Machines, but unfortunately, there's no convenient way to get those skills with this setup. There are also such useful skills as Sorcery (Wisdom and skills that partially eliminate mana deficiency), Attack (Fire Arrows, Tactics), and Luck (Magic Luck).
I decided to focus on developing Ballista skills.

In the first four days, we destroy Gremlins, Goblins near the Witch's Hut, Goblins in the east, Halberdiers, Goblins near the Sawmill, Dancers, Dwarves near the Warehouse, and Demons. On the fifth day, we stay overnight in the castle. On the 6th day, we build a level 3 Guild, defeat Unicorns and Erls. On the 7th day, we buy a Ballista, defeat Seraphs, and run to the Garrison. On the eighth day, we pass through the Garrison and get into a Galley.

From day 11 to 16, we follow this route: Garrison, Mage Treasury, Monks, Harpooners, Dwarf Treasury, Druids, Griffins, Assassins, Bears, Nymphs, Seraphs, Unicorns, and Rune Lords with Elementals.

On the 17th day, we defeat the Demon Garrison and destroy all the Devils. On the 18th day, we visit the Well and clear two Elemental Treasuries. On the 19th day, we visit the Garrison with Undead, then the Garrison south of it, and Mummies. There's nothing else to find; Chaos against 150 Erls is not effective, so we run back.

From days 20-21, we defeat Phoenixes near the Spell Merchant, buy Rain and Implosion, destroy Archdevils, and run to the Emerald Dragons. On the 22nd day, we kill the Emerald Dragons, then the Red Dragons, and dive into the portal. On the 24th day, we fight 16 Barbs, visit the Well, fight the Barbs again, and visit 3 trees. On the 25th day, we kill 30 Phoenixes and visit the Oak. That's it; we spend the remaining days traveling to the Oak, where the Red Dragons were, and at the end of the 28th day, we reach level 35.

P.S. I'm looking forward to seeing a detailed description of Virus's Walkthrough, just like everyone else.
