PFS StandardDarkness  [three-actions] Spell 2

Concentrate Darkness Manipulate 
Source Player Core pg. 322
Range 120 feet; Area 20-foot burst
Duration 1 minute
You create a shroud of darkness that prevents light from penetrating or emanating within the area. Light does not enter the area and any non-magical light sources, such as a torch or lantern, do not emanate any light while inside the area, even if their light radius would extend beyond the darkness. This also suppresses magical light of your darkness spell's rank or lower. Light can't pass through, so creatures in the area can't see outside. From outside, it appears as a globe of pure darkness.
Heightened (4th) Even creatures with darkvision (but not greater darkvision) can barely see through the darkness. They treat targets seen through the darkness as concealed.

PFS StandardDetect Magic  [two-actions] Cantrip 1

Cantrip Concentrate Detection Manipulate 
Source Player Core pg. 323
Area 30-foot emanation
You send out a pulse that registers the presence of magic. You receive no information beyond the presence or absence of magic. You can choose to ignore magic you're fully aware of, such as the magic items and ongoing spells of you and your allies.

You detect illusion magic only if that magic's effect has a lower rank than the rank of your detect magic spell. However, items that have an illusion aura but aren't deceptive in appearance (such as an invisibility potion) typically are detected normally.
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).
