Armor of Elemental Earth - Elemental Armor

A suit of armor made of dirt and rocks springs into being around a creature you touch, adding a +10 bonus to armor class and only allowing the wearer's DEX MOD to be added if it is 2 or less. The armor falls apart and the spell ends if it is doffed. A creature wearing the armor of elemental earth has tremorsense within a radius equal to its walking speed and a burrowing speed equal to twice its walking speed.

Armor of Elemental Air, Armor of Elemental Fire, Armor of Elemental Earth, Armor of Elemental Water, and Armor of Elemental Ice are one spell for the purpose of preparing, called Elemental Armor.  I apologize for not making them a single spell from the beginning.
