I've been creating custom factions for a while now and I finally got around to using the new and improved Deathworshiping (+10% HP) and bravery (+5 HP). So I started a game and I noticed that my sovereign was getting the benefits of these techs. I did some testing and this is what I discovered.
Brave (+5% Hp)
Effects Sovereign, Champions and Units
Death Worshiping (+10% Hp)
Effects Sovereign, Champions and Units.
Great Warriors (+1 Combat Speed)
Effects Sovereign, Champions and Units.
Master Scouts (+1 Sight)
Effects Sovereign, and Units.
Some reason all of the abilities (except master scouts) effects recruited champions.
Anyway, I'm glad to see that most of these abilities effect champions too:)
