@dustin4888:
Thanks a lot for the hint, Dustin. Unfortunately it didn't work.
Her archwizards have only a power of 10, so I increased their power by 4 and added her some extra lives. But 20 lives and a power of 14 still weren't enough. The archwizards still dashed against wave 2, the second poison wave. :-(
How do I have to play the storyline quest "The Great Hydra"? Which units and items do I have to use? I mean, there are only four pitches...
Can anybody here tell me the answer?
