[Flying Toaster]

I try to describe the enemy in such a way that gives players a good idea.
e.g. if someone fails a Knockdown and stun roll after being smacked in the chest (major wound) with an axe, I might say 'he is knocked back a yard and tumbles to the ground. He remains there, feebly holding his shield up, his head rocking back and forwards in a confused manner.'

If a mage is casting a spell, perhaps they feel the target resisting, and then either feel the resistance push them back, or crumble?
