The shuuders don't have to be made of real sturdy stuff since the spell immediately detontates upon impact of ANYTHING. Heck, they could be made of balsa wood for all I care.

If the fireball destroys the interposing barrier, it continues on through the opening, if large enough. I don't think an arrow slit is large enough to allow this, but its something you should consider.
dkilgo said:So, then use highly tempered shutters to displace any unwanted fireballs coming in to your guard room through the arrow slit.
dkilgo said:I agree with the shudder idea, but kreynolds what do you think of the ring?
