[Arralen]

I'm very shure you don't benefit from your neigbours luck scale, but you suffer from his turmoil if it encroaches upon your provinces.

Wrong temperature scale hurts your economy and the fighting skills of you troops. Keep in mind, though, that there are seasons in the game, which adjust the temp scale as well. Generally, though, the chance for ideal temp is much better with higher dominion.

Dominion gives you -poor- scrying ability.

Every 5 temples your maximum dominions strenght gets +1. That does not only make it harder for the enemy to repell it, it makes dominion-depending effects stronger (spells etc.) and it lets you recruit more holy troops per turn and province (up to the max dom number)

So always remember:
Dominion is a pretenders best friend !
