Investigate

Source GM Core pg. 41
As with Searching or Detecting Magic, the initial result of Investigating is usually enough to give the investigator a clue that leads into a more thorough examination, but it rarely gives all possible information. For instance, a character might note that the walls of a dungeon are covered with Chthonian writing, but they would need to stop to read the text or even determine that it’s written in blood.

Monitoring Spell Durations

Spell durations are approximate values that codify the vagaries and eccentricities of magic into a convenient number. However, that doesn't mean you can set your watch by a spell with a 1-hour duration. This is one of the reasons the passage of time outside of encounters is in your hands and isn't as precise as encounter rounds. If a question arises about whether a spell has expired, you make the call. You shouldn't be punitive, but you also shouldn't treat characters like they move with clockwork precision and perfect efficiency between encounters.

There are two times these durations matter most: when players try to fit multiple encounters within the duration of a spell, and when they want to use a spell before a fight and keep it in effect during the encounter.

Multiple Encounters

A 1-minute spell should last for multiple encounters only if the encounters happen in very close proximity (usually in two adjoining rooms) and if the PCs go directly from one fight to the next without leaving encounter mode. If they want to stop and heal, or if the party debates whether to go on, the process takes enough time that the spell runs out.

Be more generous with spells lasting 10 minutes or more. A 10-minute spell easily lasts for one encounter and could continue for another if the locations are close. A 1-hour spell usually lasts for several encounters.

Before A Fight

Casting advantageous spells before a fight (sometimes called “pre-buffing”) gives the characters a big advantage, since they can spend more combat rounds on offensive actions instead of preparatory ones. If the players have the drop on their foes, you usually can let each character cast one spell or prepare in some similar way, then roll initiative.

Casting preparatory spells before combat becomes a problem when it feels rote and the players assume it will always work—that sort of planning can't hold up in every situation! In many cases, the act of casting spells gives away the party's presence. In cases where the PCs' preparations could give them away, you might roll for initiative before everyone can complete their preparations.
