Source: Eberron Campaign Setting
You can use your wild shape ability to assume vermin forms instead of animal forms.
Prerequisite: Druid level 5th, non-good alignment, Child of Winter.
Benefit: You can turn yourself into a Small or Medium vermin. You gain the ability to take the shape of a Large vermin when your druid level reaches 8th, a Tiny vermin at 11th level, and a Huge vermin at 15th level. In no case can the vermin form's Hit Dice exceed your druid level.
Special: You can't use wild shape to turn yourself into an animal if you have this feat.
