How strong is Mercury here?

Cadent houses (3rd, 6th, 9th and 12th) come before the angular houses and are about learning, adjusting and preparing. Traditional astrology treats these as the least prominent houses, and planets here are read as working more quietly and adaptively than those in angular houses.

The 12th house corresponds to Pisces, ruled by Neptune (traditionally Jupiter). Mercury doesn't rule Pisces, so it is read as bringing its own style of thinking, learning and communication to the house's themes.

House systems differ slightly, and the sign on the cusp of your 12th house adds detail. Your full natal chart shows the exact picture.
