Very Surprising: Surprise Elementals cannot be surprised. No matter how prepared anyone is for the appearance of the elemental they are not actually ready for it. Surprise elementals automatically receive a surprise round during which no one else may act, except other surprise elementals. This occurs even if the elemental joins combat already in process, they receive an immediate surprise round then combat is resumed as normal. During this surprise round all other combatants are flat footed.
