The player have one Shrine. It can create invisible units with limited lifespan. They are called as sacrifices. The invisible units autogather favor.
There are more types of these invisible units, they have different stats. These stats can be modified by techs.
The Shrine build limit and the long training time of invisible units protect against favor overproduction.
I would like to hear more ideas.
Which techs should I research first? Which maps are favourable for Fu Xi? There are a few maps without any herdable, berry bush, chicken or duck, for example Erebus. I guess Fu Xi has a big disadvatage on these maps.
