Ranger - "Higher Vampire" [5th Campaign, 5th Mission]

I remember the first time, out of ignorance, I defeated Nicholas just for the experience, and he would constantly just run away. But if, before acquiring phoenixes, he disappeared from someone else's army, then in my case, he was probably very offended and, reappearing, immediately attacked me, without hesitation. I encountered him when he already had 5000+ dragons, and I probably would have wiped out his entire army, but Nicholas constantly created a phantom of 5000+. He destroyed all my elves.
