Glacial Bastion

You encase yourself in a Glacial Wall that fills your space until the start of your next turn, making you untargetable for attacks during the duration. This Glacial Wall has HP equal to 20 + Focus, any remaining damage is transferred to you (mitigated by your armor).  While encased, you can cast White Thunder on your encased Ice for 1 RP which removes Glacial Bastion. Other than White Thunder, you cannot take any other actions while under the effect of Glacial Bastion.   

This Spell does not provoke attacks of opportunity.
