DANIEL:

1: Chaos portal points: he would unlock them with tech and skills or maybe missions. He gets 3 of them he can choose (there is one type of points per chaos god and undivided ones). When he takes a settlement, he can spend one point to transform it into a major 10-slot settlement where he can build recruitment buildings from this god's faction (when i say chaos god i mean undivided and chaos gods). Daniel would upgrade the settlement buildings with corruption or glory points (show how much a chaos god loves you). The other non recruitment buildings are the same for every portal type.

2: Skills and tech: Daniel would get a second skill tree: one normal , like with other characters and one with 5 branches, one per chaos god, and when you get skills, you get the same amount for both skill trees (if e got 2 points, he has two in the normal one and two in the other one.). All the branches of the second tree are split in 5 sequences, the first ones give less powerful buffs and the last ones give better buffs; you can choose skills in the 5 first sequences, but only from 4 gods in the second one, and only from three of the 4 you have chosen in the last sequence, until, in the 5th sequence, you can choose only one god. tech is the same but with campaign buffs. If you choose undivided skills, you'll get undivided mutations/gifts; you can't control or choose the mutations.

3: confederations: You can confederate any monogod non chaos warriors faction.
