O druida pode permanecer em forma animal o quanto quiser, conforme citado em The Complete Druid's Handbook ,
.
Shifting shape takes one round, during which the druid cannot take other actions. The druid can remain in the new shape indefinitely-the duration of a form ends only when the druid turns back to the original shape or assumes another one. A druid can shift from one shape to another without returning to human form first.
