The Reign Of Winter
Spells: A druid casts divine spells which are drawn from the druid spell list presented in Spell Lists. Her alignment may restrict her from casting certain spells opposed to her moral or ethical beliefs; see Chaotic, Evil, Good, and Lawful Spells. A druid must choose and prepare her spells in advance.
To prepare or cast a spell, the druid must have a Wisdom score equal to at least 10 + the spell level. The Difficulty Class for a saving throw against a druid’s spell is 10 + the spell level + the druid’s Wisdom modifier.
Like other spellcasters, a druid can cast only a certain number of spells of each spell level per day. Her base daily spell allotment is given on Table: Druid. In addition, she receives bonus spells per day if she has a high Wisdom score (see Table: Ability Modifiers and Bonus Spells).
A druid must spend 1 hour each day in a trance-like meditation on the mysteries of nature to regain her daily allotment of spells. A druid may prepare and cast any spell on the druid spell list, provided that she can cast spells of that level, but she must choose which spells to prepare during her daily meditation.
