Experience.
Essentially, it shouldn't be called experience anymore, but rather the power source needed by gods.
But calling it experience isn't entirely wrong, so Kana kept it.
Faith-/Gift+/Comprehension+
These are the three power sources for gods.
Any legitimate god can absorb these three powers, just with different focuses.
The plus and minus signs reflect which of the three powers is most suitable for the current god.
The minus sign indicates that this power source will be discounted; it can still be absorbed but serves only as icing on the cake.
The plus sign indicates that this source of power will receive an additional bonus and is the type of power the current god needs most, making it easier for them to grow.
[Faith: The beliefs and concentrated will of non-divine mortal beings toward this god, will be converted into power for absorption.]
