Chocolate Covered Arrows

A set amount of random units will be defeated and removed from the camp. Roughly half as strong as Rain of Arrows. Can only be used once per enemy camp. Covered in thick, tasty chocolate, the arrows inside are well hidden. It's not clear if your foes desert due to being grateful for the sweet gift, or if they try to catch the arrows directly with their mouths. Anyhow, it weakens the enemy camp.
