Fei Zhao

Fei Zhao nods his head at the plan.
"You know, when you said you had need of my skills, I was really hoping you needed some women seduced..."

If available, Fei Zhao will collect some masterwork arrows from the weapons collection. If there are none, he will take some regular arrows, to avoid wasting the ones he spent his own gold on.
Once everyone else is ready, Fei will cast command on Lu Bu, Will Save vs DC 13 to drop his shield.
After that, he will fire arrows at Lu Bu at 1d20+8 (or 1d20+9, if he found some masterwork arrows), unless one of his companions comes up with a better strategy.
