The magic granted by the forest is precious to rangers, and some seek to harness that magical power to greater effect and earlier in their adventuring careers. They know their limited magic can never compare to the large number and variety of spells nature grants its druids, but they still vie for any improvement to their spellcasting.
Beginning at 3rd level, rangers can prepare a number of orisons, or 0-level spells, each day, chosen from the druid spell list. This ability functions like the druid orisons ability, except that the ranger’s effective druid level is equal to her ranger level. These spells are cast like any other spell, but they are not expended when cast and may be used again.
This ability replaces favored terrain.
