3ft radius so 6ft diameter at it's widest. I<em>think</em>I can add something like 1 foot to the radius by dropping 1 die from my pool to cast it;<del>but that may have been an upgrade that I don't have. </del><br/><br/>Yep +1ft to the radius for -1 die. Although a thought occurs. I'm rolling 7 die for my bubble shield. 3 Stamina 3 Craft 1 Specialty in Shields; Shield has 3 x successes HP. What happens if I don't roll any successes? Does the shield appear with 0 HP or just not appear at all?
