Radiation Dart

Use it on someone you expect to run. The dart itself barely scratches, but every hit adds radiation, and that keeps hurting after they duck behind a rock.

Picture a fresh spawn chasing you through the jungle with a spear. Two or three of these from a blow pipe and he is now fighting his own health bar as well as you. That is the job: softening up lightly dressed players before you commit.

Against a geared player it is a weaker deal. The hit itself is light, and anyone carrying anti-rad pills can clear a good part of the radiation as soon as the fight pauses. Keep it for nakeds and early roamers.

A good habit is to open with radiation darts and finish with plain wood darts, which are cheaper because they need no metal. The metal fragments in each one aren't much, but they add up when you empty a whole stack into someone who was never going to die from it.
