Prastagus

Does anyone have any idea how to activate this mercenary ability?

Well that explains it. Thanks. Time to expand those planetary defenses and farms for bigger planets.

invasion 2.5 pop + 20% soldering+conventional tactic=3.7 invasion value vs defending 22.5 pop + 80% resistance= 17.4 defending value Defender still lost. Does that even make sense?

In my game, invader with 20% soldiering bonus and 2.5 troops that totaled 3.7 invasion power. My planet has over 22.2 population, 80% resistance, with 17.4 defending power. Somehow invader won and I lost? Invader was using conventional tactic Is that a bug?

once again, the AI cheats on higher difficulty level in Galciv3. It seems to regress to Galciv 1 type of AI instead of Galciv 2. They know all the habitable planets on the map on start without exploration for example. I won my games on Beta higher difficulty when it was too easy. Now it is too artificially hard on Tough.
