Like other types of nature priests, druids know the spells of their divinity, though they can select other druid ones to be ongoingly substituted instead. Druids can also prepare a bonus druid spell of their choice for every spell level they have. In addition, they can access other spells thanks to their druid mysteries, detailed in Part II.
For example, a druid of the Dagda would usually have Enlarge on his spell list, but could opt to replace it with Entangle from now on. In any case, he can prepare an additional druid spell for each level on his list, which could also be Entangle or other ones.
