Sacred Haven of Debauchery

Did you buy them? But why? The battle is quite easy with him.

Well, how do I put it... I'm one of those who likes challenges. That's why I'm playing "Hero on the Arena". So I have to buy them...
And in the original game, it's more profitable to buy them and search half of Endoria... Then it will be easy not only at the end but also at the beginning...

Regarding the reserve, I just don't quite understand why you would change units. About rage, yes, it is lost, but mana is restored. And in case of extreme need, there is beer and rage potions.

The best option is when you have plenty of mana and rage. x) And you need to change units for "battle optimization"...
