Eggshell

Eggshell [minor] by Iczer

'Armor? Oh no my friend..you are very much mistaken'

The character can create a temporary cocoon of calcium strands that shield him from harm. While on the inside, he performs a temporary mutation.
The shell: Forming the shell requires 2 actions. Once formed, the character has an AR of 10 (natural). 20% of his remaining SDC goes toward making this shell.
Duration: The shell lasts for 1D4 melee rounds, unless shattered earlier.
Transformation: At the end of the duration, the shell cracks and the character steps out. His new form enjoys a +6 bonus to two attributes and gains BIO-E equal to the shell's remaining SDC. This monstrous state lasts 1 minute per level before the character returns to normal (Sans the spent SDC)
