Tactics for Dungeon.

No eyes are needed at all, 200%. Take a Shaman and let him break everything and everyone with his troglodytes.

I disagree with you, Kolya.
Troglodytes are good, but extra mana never hurts.
You can use troglodytes to defend enough to build and get cats.
(max out the gnome pits and small naga banks on the first day). I think this should also be used for building.
