I was constantly short on cash, so on the first week I only managed to get the unicorns in the Citadel; thankfully I found 2 crypts, but they gave minimal payouts ((. On day 122 I capture a secondary Castle and find a dwelling of horses nearby. On the second week I build up the Castle in my hometown and in the secondary town with horses. On day 132 I failed to notice that the enemy had broken through the ГО and was transporting an extra army with a scout hero right under his nose — luckily he didn't touch them. On the third week I found a lot of gold in 3 max crypts, 1 dwarf cottage (15 each with upgrade), and 1 nagabank attack, so I bought up for the final battle as follows: 53 Grand Elves, 60 Pikemen (raised from a Pandora's Box), 38 Centaurs, 12 Pegasi, 13 War Unicorns, and 11 Champions, with Kyrre at level 12 (Archery, Logistics, Attack, Defense maxed out) but no spell book.
Thanks for the game!
