Detection
Detection effects allow you to detect the presence of certain types of creatures, effects, devices, energies, materials, organizations, phenomena, or substances.
Selection Upon learning this spell, select one type of creature, effect, device, energy, material, organization, phenomena, or substance. This spell detects this selected subject. You must get this selection approved by the GM and ensure it makes sense for the setting. The school of magic is also determined by the subject. For example, if you selected "blood" it would be biomancy but if you selected "bones" it could be biomancy or necromancy and if you selected "gold" it would be transmutation. Divination would work for nearly anything as well.
For the duration you can sense the selected subject automatically if you are touching it or otherwise sharing a space with it. When using the Search or Study action, you automatically detect it if it's within Close range. You also gain a magic bonus to all Perception checks to detect the subject equal to the double the tier of this ability.
Heightened (3rd) You learn the rank or level of the most powerful magical effect the spell detects, as determined by the GM.
Heightened (4th) As 3rd rank, but you also pinpoint the source of the highest-rank magic. Like for an imprecise sense, you don't learn the exact location, but can narrow down the source to within a 5-foot cube (or the nearest if larger than that).
Heightened: Each additional tier increases the bonus to Perception checks. Every odd tier increases the automatic detection range: Medium at 3rd --> Long at 5th --> 1 mile at 7th --> 10 miles at 9th, etc.
Additional Selection (+1): Add another selection to the list the spell can affect.
Details (+1): The spell allows you to garner additional information about a subject within the automatic detection range so long as you're observing it. Each time you use the Study action to study it while observing it, you gain the benefits of 3 rounds of study instead of just 1. The second time this upgrade is applied it increases to 1 minute and it increases to 3 minutes the third time and 10 minutes the fourth time and 30 minutes the fifth time and 2 hours the sixth time, etc.
Sympathetic (+1): This spell gains the sympathetic type.
