From the start I got 16 archers. There is a stable next to the castle. A Griffin Conservatory level 4 and an external dwelling of unicorns on the respawn.
As a result, by week 1 day 1 I have cavalry at the castle + external dwelling.
On week 2 day 2 I take the Griffin Conservatory and decide to go into the underground. For some reason I thought it was a treasure zone =)
There I take out Nila with a Medusa, having previously taken the Dragon Fly Hive.
gg. Thanks for the game!
