Stage 5 of the John Van Caneghem Tournament

TO wolf64 - you've explained it beautifully, but I'd like to see a replay of the battle with the elementals. I'm very interested in the tactics of fighting 4 stacks of 2 goblins against 4 stacks of 50 elementals. The ballista is certainly powerful, but without Luck and other advantages, at best, you can destroy a stack of 50 elementals in 3 turns. This means that to destroy all the elementals, you need to use the ballista at least 12 times, or even 10. The question is, what were the elementals doing all that time? Perhaps the secret lies in the Town Portal skill. In general, I'm very, very interested in seeing a replay of this particular battle; I'm waiting!
