The Element of Surprise

Random, silly thought which I have decided to transform into gamable material: A surprise elemental. A being of pure, raw unexpectedness which hails from the elemental plane of Surprisingness (few have been there, but they report that it certainly was not what they expected).

The stats here are for a "large" Surprise Elemental, bigger and smaller versions exist.

Special Abilities:

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.

Shocking Slam: The surprise elemental's fists are very shocking, so obviously they inflict bonus electrical damage.
