Improved Elemental Wild Shape

(Dungeon Master's Guide v.3.5, page 209, DnD 3.5)

[Epic, Wild]

You can take the form of a larger variety of elementals than normal.

Prerequisite

WIS 25, ability to wild shape into an elemental

Benefit

Your ability to wild shape into an elemental is expanded to include all elemental creatures (not just air, earth, fire, and water elementals) of any size that you can take when wild shaping into an animal. For instance, if you are normally capable of taking the shape of an animal of Huge size, you can now wild shape into a Huge elemental creature. You gain all extraordinary and supernatural abilities of the elemental whose form you take.

Normal

Without this feat, you may only take the shape of a Small, Medium, or Large air, earth, fire, or water elemental.
