I had an AI that i befriended in a game. i loaded up on the envoys, did lots of diplomatic research. formed several pacts with him.... dumb AI didnt acquire more than 4 planets. my intention was to see what effect my "ultimate pact" had on my combat abilities as advent.

now as i understand it, there is a cap of +1.5 to relations per planet. so him having 4 planets, if i understand this correctly, the maximum relations would be 16? (which i dont think is enough). is there anything else that can be done to boost relations at that point? or does the AI have to expand?

i also get confused as to what i can and cannot do if, say, my relations with them are 14, but their relations with me are 7? is there anything i can do to improve their relations with me?
