Who says ball of lightning isn't the best dragon ability?

Absolutely It was just a tool to up the damage - and to check out some of the game mechanics I was wondering about. In essence it was a simple test - I wasn't aware that the damage will jump that high, although I admit I was in total awe when it did.

However, even if the troop is left with more hp, it's also left with 30% less damage. That is serious as well.
