=== Priests (including Druids) ===
The spells that priests, rangers, druids, and paladins will have access to will depend heavily on the diety they worship.  The DM will provide a list of allowed/disallowed spells to the player as part of the character generation process.

When users of divine magic cast a spell, they invoke a prayer to their patron entity or power; usually the lower the spell level, the lower level of minion or servant of the higher power that will be granting the request. Users of divine magic do not need to spend time studying spell books, as users of arcane magic do, but they do need to spend some time in daily prayer to keep their relations with the higher powers on a sound footing. In game terms, this equates to about an hour per day. Failure to do so for a period of days will eventually manifest itself in the form of spells not being granted – the caster will perform the motions and invoke the words or gestures of power, but no effect will manifest itself, and the “slot” will be used. There are no percentages or rules associated with this effect – it is dependent on deity and situation, and is essentially a DM’s ruling.
