You have arrived at the right place if you’re planning to run the best Medic build as Obi in Killing Floor 3. The Medic role requires smart usage of your heals, as there’s a hard cap per round and each one costs resources, so you have to make them count.
The Medic’s job is to keep everyone alive. Using weapons that come with built-in healing, such as SMGs that fire syringe darts, will come in handy, and your gadgets can also throw up protective fields.
You can still take down weaker Zeds while dropping biological grenades to hurt enemies and patch up teammates at the same time. With that said, here’s the best Medic build with the right weapons, tools, skills, and bonus abilities.
