Saju gives you four pillars. Each stem and branch belongs to one of the Five Elements. Your Day Master is the heart of the chart.

Stats: Charm comes from Fire/Water and the Peach Blossom star. Wealth is what your Day Master controls. Intellect is what it creates plus what feeds it. Grit is your own element. Influence is what controls you. Sun, Moon and Rising signs add a little extra.

When one Day Master controls the other (Water douses Fire), the attacker gets +6% power. Pillars follow the exact solar terms (the Sun's real position), the hour pillar uses local mean solar time when you pick a city, and planet signs are computed astronomically (Moon within a fraction of a degree). Entertainment, not prophecy.
