For example: Fangthorn the troll has a
Threshold of 4, a suit of armor worth 10, and a
Shield spell and a Bless spell active, giving him
20 points of protection before damage will be
given to his body. He is attacked by Terin, who
is calling “three normal.” The first few hits from
Terin will remove Fangthorn’s Shield spell, the
next few will breach Fangthorn’s armor, and
the next will remove his Bless spell. After those
20 points are lost, Fangthorn will begin saying
“no effect” to the rest of Terin’s blows since
they are now affecting only his body.
