As a full-round action a druid may choose to expend one of his daily uses of wild shape to undergo rapid regeneration, channeling the metamorphosis magic to repair his body instead of change its form. Rapid Recovery allows you to reroll any fortitude saving throws against poisons or diseases (including magical diseases, but you do so with a -4 penalty) that may be affecting you, success means that effect immediately ends. You receive 1/2 of your druid level in points of healing to go towards repairing your physical ability scores, so a 9th level druid may recover 4 points of damage across his strength, dexterity, or constitution scores. In addition you heal a number of hitpoints equal to constitution modifier times your druid level for 3 rounds.
Special If you have 5 or more ranks in knowledge (nature) you may use this ability as a swift action instead of a full-round action
