Nanomachines is a defensive Equipment item that helps you with healing. This upgrade's Defensive Upgrade version is Repair Bots.
Effect[]
When injured, Nanomachines give you ability to heal 3x faster than normally. This works when the user character is below half of his HP (50%).
The effect is not as fast as Rapid Regen and after picking up medical packs, but it can help you very much if you hide in the cover.
Tips[]
This equipment is especially effective when combined with a hero with the Healthy upgrade, as he will heal constantly AND heal 3x faster after 3 seconds of not taking damage.
