Painful...

Cleric fills up his cheeks with air and exhales 'electrocution'
Magical rifts open above Cleric and hideous rays of POWER combine his spell.
An electrocution hits you.
Cleric sees right through your puny mirror images.
That really HURT!
You lose your muscle control as electricity JOLTS through you!
You are no longer stunned.
You fall unconscious from the pain.

You die.
