Trauma kit
What is a trauma kit?
Trauma kits are a basic healing item. They come in the form of Single-use (one use, duh), Medium (five uses), and Large Trauma Kit (ten uses). When used, bandages will be applied that cause small, but steady healing. The effectiveness of the healing can be increased by sitting down directly after application. You can't use a trauma kit unless the target is wounded.
For a larger, but not sustained, burst of healing, use a nanite healer.
One strategy for "stacking" healing during combat is to use trauma kit on yourself as soon as you are injured during combat, and using nanite healers as needed in case of critical hits. That way you have a constant stream of healing to offset the damage accrued in combat.
Where are they?
Medium trauma kits can be found, among other places, in Meds 4 Less in Freedom City, shown as "ML" on your map. A little careful poking around will turn up several varieties in the Crack Mansion.
