hi,
here is a short list of the curses and blessings I encountered. No doubt they have been listed before, but searches on 'curse', 'blessing', and their names did not reveal much.
Ceres:
a) destroys crops
b) sends locusts (difference with previous: lands remain barren for several months)
c) boosts fertility of crops
Mars:
a) Curses a fort
b) Sends a spirit to watch over city. Spirit kills about half a legion of attackers or was it 40%?
Mercury:
a) Spirits away some goods from your granaries / warehouses
b) rains fire and hail destroying granaries / warehouses
c) Fills granaries
Neptune:
a) sends a storm sinking all ships
b) doubles all pay (both land and sea trade, even natives) and garnts smooth passage
Venus:
a) makes people feel sad
b) spreads disease
c) make speople feel happy (and a baby boom)
Most of them seem to have two curses and one blessing.
I find some curses are worse than others. Many depend on the scenario. For instance, I found I could safely ingnore Mars on the first peaceful career scenarios - not on all.
If Ceres takes away your crops, your crops tend to come in in bunches years after. I prefer the to come in gradually.
The locusts are even worse. The land must first heal of this disaster, often taking months. And as we all know, you cannot live from food imports.
Somehow I no longer throw an early party at mars, most scenarios grant you some time before the first crosses appear on the empire map.
Neptune now is the main source of my parties. I can always use an extra 10K or so of money. You can probably safely ignore him if you do not need extra money, have no sea trade routes and no fishing.
I can not ignore Venus, as continued neglectance causes her to spread diseases in the town against which doctors are of no avail.
No doubt some of you can point out that Mars & Neptune also have two curses, just like the others.
