In the Worlds of Crowfall you can find imposing God Outpost that are shown on the map as big statues with the name of the God they are bound to worship. Make sure to drop by at these outposts whenever you can, as they provide powerful buffs that last for one hour. For each Faction there can can only be one buff active at the time. So one buff of the Sun Gods, one of Earth and one of Moon. Conclusively you can run a total of 3 god buffs in Crowfall. If you pick up a new buff of the same faction the old one will disappear.
Check out my other article on the fort buildings as well. There are some buildings that give you a buff as well.
The following Info-graphic gives you an overview which god gives you what type of buff. Down below I listed all the buffs categorized by their faction and a description of the effects.
