I've started a game in Pathfinder, as a Druid.
Like any other spell caster, Druids need to rest in order to replenish their spell uses. However, Druids "know" all the spells in the Druid spell list —they are just required to prepare a limited amount per day.
In the game, we came across a scenario where my PC was being chased, and was therefore preoccupied, as the sun rose. Obviously, he couldn't really stop and prepare anything at that given time, and so we said that I was “stuck” with my current list of spells, until next time.
So, as a Druid, what do I need in terms of “when”, and “how long”, to prepare my spells for the day?
