Thread of Certainty

I said 'the wallet of the richest man in this town', and it knew.
I said 'the head of the one who blinded my right eye', and it knew.
I said 'the heart of the one who loves me most'... it knew.

— Last recorded words of Orven Nailwright, hedge wizard of Varn's Hollow.

You speak a detailed instruction describing a specific point in space. A metal needle, tethered by a silvery thread, animates and travels toward the described location. The needle always arrives exactly three seconds after the spell is cast, regardless of distance.

If the location exists and is accessible, the needle strikes with sudden force. If the target is part of a creature, the creature takes 1d6 damage. Should the location be especially small or vital, increase the damage by another 1d6. The thread extends only as far as needed, and becomes perfectly taut when the needle lands.

If the described location no longer exists, but remains physically accessible (e.g., an empty space where something once stood), the needle stops at the original point in space. If the location never existed or is entirely inaccessible, such as a bad description or a location not on the same plane of existence as the caster, the needle drops harmlessly to the ground.

Precise spatial relationships may be used in place of named locations (e.g., "the distance between my fingertip and the center of the keyhole"), allowing for pinpoint targeting. The more specific and accurate the description, the more accurate the targeting.

Tension Recall. Once the needle has landed, the caster may choose to pull the thread, either to retrieve the needle, drag the struck creature or object along the needle's original path, or to pull the caster toward the object or creature. Creatures struck by the needle must succeed on a Strength saving throw (DC equivalent to your spell save DC), or be pull toward the caster. Immovable objects may instead pull the caster toward them.

At higher levels. When you cast this spell using a spell slot of 3rd or higher, you may describe one additional target location per slot above level 2nd. Each needle travels independently.
