Round table

I'm not writing about Inferno; having a crypt with 111 creatures there is a utopia.

Why? Kalh, with built-up Gogs and 1 native hero, can deploy 25-32 upgraded Gogs on Inferno's land with a speed of 8 in the crypt + a garrison.
With a Gogs boost and a Demons boost, I took the Preserve on day 3 with a stack of 39 Gogs and 4 Demons, plus approximately 6 Hellhounds, 15 Imps, and some single units, although it's quite simple to use 4 Demons and 5 Hellhounds (or bring in another 4 Demons from the castle) + single Imps as a cover for 2 rounds.
The hero was level 3, with Advanced Archery and some basic Earth skill, but without a spellbook... I lost a couple of Gogs (from the Royal Guard's first attack) and almost the entire garrison, but I gained +1 Angel.
P.S. Dirty Player can confirm this about Inferno.
