Tulrun's Tracer

4th-level divination

Casting Time: 1 action
Range: Self (10-foot radius)
Components: V, S, M (a pinch of phosphorus or a glowing life form like a glowworm or bioluminescent fungus)
Duration: Concentration, up to 1 minute per level


This spell creates a continuous, luminous pathway that reveals the most recent route of a creature specified by the caster. The caster must verbally describe the creature in detail during the casting. If the described creature has not passed within 10 feet of the caster's location within the past 24 hours per caster level, the spell fails.


Effect:

  • The tracer manifests as a glowing line within 10 feet of the caster, tracking the path the described creature last traveled.
  • The line moves at a rate of 60 feet per round, tracing the route taken by the creature, provided the creature was in contact with the ground or a living mount.
  • The tracer is intangible and cannot be physically interacted with, disturbed, or destroyed by mundane means.

Special Conditions:

  • Creature Contact: The spell cannot track creatures traveling entirely through the air or other mediums without touching the ground. It can track through water and will cross physical barriers and gaps of up to 15 feet.
  • Resilience: The tracer is unaffected by pass without trace or other spells of 4th level or lower that would obscure the path. It can be disrupted by spells like dispel magic or areas of magical darkness.
  • Teleportation and Plane Shift: If the creature teleported or plane-shifted, the tracer ends at the point of departure, and the caster receives a mental image of the destination. If the creature boarded a conveyance (e.g., a ship, cart, or flying carpet), the tracer ends there, and the caster receives a mental image of the act but not the final destination.

Spell Termination:
The tracer fades when the duration ends, the path reaches the target creature, or it encounters a condition it cannot follow (e.g., teleportation or planar travel).


Identical Creatures:
If multiple creatures match the description, the tracer attempts to follow all paths simultaneously. The caster must focus on a single path within 1 round; otherwise, the spell follows all paths, splitting its remaining duration proportionally among them.


At Higher Levels. When cast using a spell slot of 5th level or higher, the tracer’s tracking speed increases by 10 feet per slot level above 4th, up to a maximum of 90 feet per round.
