In the first run, I completely cleared the two treasure rooms! And I got the brown companion, Falx. In the end, all the gnolls were used up on the 117th level, which was the second-to-last strongest army. It was very tight financially, so I postponed building the Vivarium until level 117, until I found a market! Hooray! Vivarium in the Citadel. One of the treasure rooms had 2 hives and 3 nests of firebirds.
In the second week, I gathered 2 hives, what kind? 4 each, and that's enough; I lost more trying to break through the guards. The firebirds gave me hope. But near the last one was Pandora, guarded by 50+ simple djinns - I attacked with 80 units with a group. I only managed to defeat 60. Tazar leveled up poorly; the result was a failure.
Thanks for your time.
