Bluff

Bluffing your opponent stops the battle until the victim realizes you
tricked them.  You can use your opponent's confusion to your own advantage
for as long as it lasts!

A good use of this skill would be to bluff and then immediately stun your opponent. Here's an example alias:
alias X bluff %&stun %
Usage:
X <enemy>
