A THREAD FOR NEWCOMERS!

With what troops and hero characteristics (is this even possible?) when playing as Fortress, can you capture a Green Dragon lair in week 1?

I decided to try it out for a change. 21 Elves + 70 Kentaur (built in the city + one lair each + come with heroes - I estimated), ranger heroes without artifacts or magic, but visited 2 stone circles (level 3) and 2 upgrade shrines (+1 attack, +1 defense). I cleared it without any problems, but I didn't try to reduce the number of heroes or minimize the army and losses.
