What it does well
Genuinely open-minded and hard to discourage. Says the thing nobody else will.
Fire · Mutable · ruled by Jupiter
♇ Pluto in Sagittarius ♐
Pluto governs power and transformation — a generational placement. In Sagittarius, that function takes on expansion, honesty and appetite for the unfamiliar — a Mutable Fire expression ruled by Jupiter.
Where it strains
Says it without checking whether it needed saying, and leaves before the consequences land.
Reading a placement properly
Pluto in Sagittarius describes a function in a style. It says nothing yet about where that plays out — for that you need the house, and the house needs a birth time. A placement read without its house is half a sentence.
