I have built the special buildings -the Adularia Chamber, the Palans Engine, and the Blasting whatever- in my capital and built Barnaxis. The question I have is "do i have to maintain control of the mana for the building effect to work?" I had only two mana sources (i play crowded maps) and i used one for metamagic. I made the nessesary mana for the building and then dispeled the node and built the next one. I waited 50+ turns to Build Barnaxis, waiting for sorsory and a mage, but now lo and behold he has no powers... Is that how its supposed to work?
