A note about health, healing. yadda yadda:
When we started up The Artifact there was a bit of confusion as to what the First-Aid & Medical Kits did for you exactly, so here are both descriptions:
First Aid Kit
Available at most drugstores and camping supply stores, this kit contains enough supplies (and simple instructions for their use) to treat an injury before transporting the injured person to a medical professional. A first aid kit can be used to help a dazed, unconscious, or stunned character by making a Treat Injury check (DC 15). A first aid kit can be used only once. Skill checks made without a first aid kit incur a -4 penalty.
First aid kits don't actually heal any hit point loss though. They are a one time use item.
Medical Kit
About the size of a large tackle box, this is the sort of kit commonly carried by military medics and civilian EMTs. It contains a wide variety of medical supplies and equipment. A medical kit can be used to treat a dazed, unconscious, or stunned character, to provide long-term care, to restore hit points, to treat a diseased or poisoned character, or to stabilize a dying character (see the Treat Injury skill). Skill checks made without a medical kit incur a -4 penalty.
Treats Hit point loss, and a ton of other things. This has enough supplies for multiple uses.
