The most Deadly Assassin

The Healer was walking around and saw a guy get mugged. "We will see how that guy likes getting beat up!" She muttered.
The Healer then stalked the guy till he went into an ally. "Well well well. What do we have here? A mugger. Let's teach you a small lesson." The Healer said.
The guy looked smug. "And how are you going to do that?"
"Oh, I don't know, these maybe?" The Healer said, pulling out her sword from her back. The guy looked scared and started running. The Healers eyes turned glowing blue, and an invisible shield came up in front of him. "So either come with me and give that man his money back, or you will be very hurt."
The man nodded. The Healers eyes went back to their normal brown and the sheild came down as she put her swords away.
