Single black dragon - how far can you get?

[DGDobrev]

Well done

The info thread is correct (I had him skip a turn), however, chances of doing that are very low, like from 1/30 upwards for each round (so it's not guaranteed that he'll skip a turn even once in 30 rounds), because the chances of him casting his mass attack when there's nothing he can hit or there's nowhere to place a tower are so high.
